are supposed to rejuvenatc jaded and tired professors, and London did not
disappoint. It is at once a vibrant, impressive, and culture-laden center,
offering rich rewards to the casual visitor, but much more so to the long-time
dweller. Many of the old stereotypes have to be discarded. For example, the
classical London fog is now a rarity, practically a myth, since smokeless
fuels have been made mandatory. We had a gorgeous, sunny spring, and even
the rainier July hasn't been unpleasant. Comfortable, centrally heated flats
are readily available, at least for visiting Americans with distortedly (for
the U.K.) large incomes. And food, not usually cited as a strong attraction
for the visitor, is excellent, again mainly for those who can pay a premium
price. This change is at least partly due to a large influx of foreigners;
Greek, Chinese, Italian, Indian, and Pakistani restaurants abound, and French,
Turkish, and even Kosher restaurants can be found.
an American, the most impressive thing about Lon-don is its cleanliness and
orderliness compared with, for example, New York City. The parks are incredibly
well kept, despite very great public use. Not only is the grass well cut and
the trees well pruned, but there are excellent floral displays which are changed
frequently. Vandalism seems to be minimal. Rubbish is collected promptly,
and in most parts of the city, it is rare to see papers blowing around the
street. This is due partly to better anti-litter campaigns and practices,
but mostly to efficient and abundant sanitation help. Traffic and noise are
serious problems; the former is combatted in part by an efficient underground
system and probably made somewhat worse by the numerous double-decker buses
which are such an integral part of the London scene. We found the noise problem
most serious when low-flying aircraft approached or took off from Heathrow
Airport during hours when most people like to sleep.
The London theatre lived up to its reputation. The world's best English language
productions can be easily (except for the Old Vic) obtained at truly nominal
prices. In addition, opera, ballet, art galleries, and fine music are available
virtually every day and night. Needless to say, cinemas are abundant and have
a great variety of offerings. We found the jazz fare a little on the slender
side, but what we found was of high quality. We are no experts on discotheques,
but the two which we had the occasion to visit seemed as noisy and psychedelic
as their American counterparts. The miniskirts seemed provocatively short to
my middle-aged eyes, and the girls extra-ordinarily attractive, well-scrubbed,
and carefully groomed. We lived in a very cosmopolitan neighborhood just north
of Kensington Gardens, and I have never seen, in so small a space, such a variety
of types living harmoniously. Interracial couples were very common, and elicited
no unusual comments or reactions.
aspects of life in Britain deserve special mention to Americans. The first
is the radio and television system, which carries no advertising and is supported
by taxation and the sale of licenses to hearers and viewers. While acknowledging
that there may be greater diversity of offer-inns in the U.S., I found the
entertainment value much greater in Britain. What a joy to be able to hear
15 minutes of uninterrupted news, sans sales pitches for cigarettes, aspirin,
or automobiles! What a joy to see plays lasting several hours, or to hear
uninterrupted concerts! I am convinced that we Americans are underprivileged
in our listening and viewing.
newspapers arc also noteworthy. We read the Times and the Guardian daily and
the Observer on Sunday. The news and features seemed of very high quality
to us .. . no better than the very best U.S. papers, but equally good, and
somewhat more succinct. The Times carries a daily science column of very high
quality, and the occasional longer articles seemed to me of higher quality
than what we usually see. Of course, none of these papers carries a daily
horoscope, which may alienate some potential American readers. A convenient
feature of the Times is that front page stories are not carried over to pages
further back. A great convenience! Also, there is much less advertising copy,
so that the papers are less bulky than our own, but not at the sacrifice of
news reportage. There is much less attention to crime and criminals, especially
before trials, and a dispassionate attitude seems to be maintained. For example,
the man the U.S. claims is James Earl Ray, the alleged assasin of Dr. Martin
Luther King, is referred to in the British press only as Ramon George Sneyd.
a word about the National Health Scheme. I talked with several doctors and
people from many walks of life about it. Almost everyone, while admitting
to certain inefficiencies and shortcomings, says the system is an outstanding
success, and will never be scrapped. Everyone now has access to medical attention,
irrespective of ability to pay, and without having to submit to the indignities
of paupers' oaths or their equivalent. This is a great accom-
and one which I personally would like us to emulate.
worked at the Department of Biophysics at King's College, which is part of
the University of London. The lab, formerly a seed warehouse, is located on
Drury Lane (this always elicits some chortles from limerick afficionados)
near Covent Garden market. I can testify that it is a very lively and picturesque
neighborhood, where Billings-gate and very proper English are encountered
with approximately equal frequency. The lab was founded and organized by Sir
John Randall, a physicist who turned to biology, and who now investigates
the nature and growth of flagella in Chlamydomonas. The Wellcome Foundation
furnished some of the money for converting the old ware-house into a handsome
and well-equipped lab, and the rest of the operation is supported by the Medical
Research Council. Among the other groups at the lab are those under Maurice
F. H. Wilkins (co-Nobel Laureate with Watson and Crick for DNA investigations,
currently interested in the structure of membranes), S. R. Pelc (well known
for autoradiographic techniques), several groups working on muscle structure,
and a cell biology group under H. G. Davies.
research activities have centered about an attempt to localize various biochemical
activities in plant cells. Mostly, I have been working with the Zeiss Universal
Microspectrophotometer to localize phytochrome in cells of Avena coleoptile
tips, etiolated pea epicotyls, and other favorite objects of phytochrome investigations.
Using a 1 in diameter microbeam, I scan the various cell organelles under
high power to attempt to find regions with high absorbancy in the 660 m1.
region. When I find one, I irradiate with high intensity 660mµ light
from the mono- chromator, then quickly scan this region again for spectral
shifts. If I find a decline at 660mµ and an increase near 730 mlt, I
suspect the presence of phytochrome; if subsequent irradiation with 730 reverses
the spectral changes induced by 660, this supposition is strengthened. I think
I've had some good luck, and this is agreed to by well-known experts in the
field of phytochrome. Since this is no place to report scientific data, I'll
say no more. Watch your favorite publications for more news, as the saying

have also been learning the stripping-film radioautographic technique, as
it applies to the localization of soluble compounds in the cell. This involves
cryostat microtomy without fixation (which would move around soluble compounds),
application of the section to the film under minimal safelight conditions,
and development after weeks or months of storage of the section and film in
the deep-freeze. I tried to use the technique to localize IAA in the cell,
but all I got was uniform distribution of the label. I have some ideas about
how to improve this technique (which is terribly exacting), but no interesting
found myself giving many, many seminars at frequent intervals. First of all,
as the first botanist ever to have worked in this lab, I spoke four times
on "some botanical problems of possible interest to biophysicists." At least
one young physicist seems to have been seduced into botany as a result. Other
London talks included Bedford College, Imperial College, Queen Mary and Queen
Elizabeth Colleges. I also visited University College, the Chelsea Physic
Garden and, of course, Kew Gardens at rhododendron time. Seminar talks outside
of London included Cambridge, Oxford, Wye College, E. Mailing, Liverpool,
Glasgow, Exeter, E. Anglia, Reading, Sussex, Aberystwyth, and Bangor. I think
I got a very good cross-section view of British plant physiology, and found
myself frequently introducing British botanists to one another. They seem
not to get around as much as we do!
attended three meetings. One, the decennial anniversary of the phyrochemical
group, met at Cambridge April 1-3, 1968 to review changes in our understanding
of plant chemistry over the last ten years. A book will result, under the
editorship of J. B. Harborne. The Royal Society had a one-day symposium in
London on cytoplasmic organelles, including outstanding talks by J. Bracher,
C. de Duve, D. H. Northcote, and J. Gurdon. The Tate and Lyle Co., Britain's
largest sugar producers, sponsored a two-day conference on "Photosynthesis
in Sugar Cane," organized by A. J. Vlitos, an American who is research director
of their laboratories. The conference featured talks by many Americans, including
M. Gibbs, J. A. Bassham, R. C. Fuller, and W. M. Laetsch. All three meetings
were entertaining and rewarding.
the trauma of having imminently to face a return to the life of a working
man, including committee meetings, telephone interruptions, and the other
nondesiderata of university life, I feel this change of pace has been tremendously
rewarding. Most of all, it has restored to me the feeling that working hard
at uninterrupted scientific research is one of the most enjoyable of all human
activities. This, after all, is what brought most of us into the field.
to, General Botany
is the science of plants, and a general botany course should acquaint a student
with them. That live plants are quite often absent in such teaching is implied
by Reed and Ihrig (1968) in, "Botanists have been remiss in exploiting the
classroom possibilities of living plants." Apparently many kinds of substitutes
have invaded the class-room in lieu of live material. What is the best procedure
to follow, and why was the living plant neglected?
many years of experimentation along the lines of procedure and materials,
I have found that the most meaningful course was the one in which live, fresh
material was abundant. Not only does this apply to college fresh-men, but
it applies even more so to teachers. It is surprising how vaguely people understand
plants. For the past several summers I have had N.S.F. students who have had
several or more years of high or junior high teaching experience. They had
their college degrees with majors in mathematics, physics, chemistry, zoology,
biology, agriculture, horticulture, or some other closely related field and
were teaching one or several courses in high school science. They admittedly
had had very little, or no, formal botanical training and needed such work
to enrich their teaching. Many of them were quite well read and could converse
in a "bookish" way about the ultrastructures and energy changes of living
cells and the theories of the origin of life and evolution. It all sounded
plausible; and yet if they were pushed, one became aware their information
was often dangling and with little, or no, foundation. So for them, it was
necessary to supply a foundation course.
for us, the plants were usually not far away. A trip to the garden, greenhouse,
forest, park, road, rail-road rights-of-way, and especially the weed patches
along streams supplied some desired material. Many kinds and stages of plant
material could be grown in the greenhouse, where experiments could be started
or performed also.
one entered the classroom armed with good, live material. Observations of
structures or interpretations of experiments would be asked of the students.
Razor or knife cuts would be suggested to reveal inner parts or to make microscopic
mounts. The student was asked what he saw or how he explains it; seldom was
he told. It is not surprising when students have the material in their hands,
or if they have made a micrscopic mount, that their answers are quite accurate.
They soon learned to compare specimens or micrscopic mounts. A surprising
amount of helpfulness develops, and the students criticize each other's material.
They see and tell each other what to see. With their observation not of one
microscope, nor of one specimen, but of those of the class, the material covered
proceeds at a fast pace. No one need sit at his own micro-scope hunting and
hunting for some good material that is not there. By admitting that his material,
this time, was not good and by observing the better mount and sketching it,
if necessary, much time was saved. Most of the time someone else at the table
or in the room has the best material, and we all use it. Conversely, at some
time every student has the best material; and he could be proud or even boastful
of it. This mutual helpful rivalry carries the class right along.
course, it was necessary to introduce the most recently published observations
or theories. After the students have examined the gross characteristics and
structures of live cells by their microscopes, the pictures and explanations
from the electron microscope were used to bring them up to date. Because the
student prepared his own microscopic mounts, he has acquired a feeling of
position and location. By superimposing the electron microscope pictures on
his own, they are not detached but become part of his experience. After observing
the dry weight loss, the giving off of carbon dioxide, the use of oxygen,
the heat energy released, plus the difference between alive and dead cells,
the student acquires some feeling for respiration. At least various everyday
problems can be explained at these levels. Just how far one should carry the
ultimate explanations in chemical terms as published in current literature
depends upon the time and maturity of the students.
by oral directions, observations, interpretation, discussions, and explanations,
the student explores facts about plants in a research atmosphere. And he has
a challenging, good time doing it with his classmates. This type of teaching
is quite easy if one has very good material and the experiments are in their
prime. Such teaching requires the constant checking of materials and the watering
of plants even on Saturdays or Sundays. Teaching general botany becomes a
way of life, for one is constantly looking for fresh plants and new ideas.
contrast to the preceding, there are available to the instructor in general
botany many items or materials pre-pared by commercial concerns. Textbooks
have been writ-ten and rewritten, and many of them are well illustrated. A
good text, or texts, is a must for most of us, at least as a reference. Furniture,
microscopes, and laboratory manuals are recognized necessities. However, serious
doubts can be raised about some laboratory manuals or their use. If the directions
for the observations or experiments have all the answers written into the
text, then why bother to do the exercise? The exercise turns out to be a re-run,
and it is little fun to do something with all the results already before you.
Laboratories almost run alone by giving the student so many directions in
a manual; the student has little time for anything else. The ultimate in laboratory
guides was a class observed in a large university where the students read
the study questions and the instructor dictated the answers.
aids written and drawn by competent persons are available for such teaching.
All kinds of reprints, charts, models, prepared slides, lantern slides, transparencies,
and films have been produced. As a matter of fact, the commercial concerns
have almost monopolized some botany courses. There are sufficient "help" materials
to allow one to give a year's course this way. These materials can completely
replace fresh material. My, how these materials save the instructor's time!
But are we doing good teaching by saving the instructor's time? Maybe our
teaching methods are reflected in the students' attitude of hating science?
We in botany, in general, have not done a good job in teaching our subject.
Just investigate the state of general botany in many schools.
teachers prefer to, or of necessity must, teach by
lecture .method; and some of the prepared materials are very helpful. Just
how a lecture comes "alive" depends on the ingenuity of the instructor and
his use of fresh and prepared materials. Some lecturers do an excellent job
of presentation, and the system should not be condemned be-cause of a poor
performer. However, the lecture should not be used as an escape. As a colleague
remarked, If you have time, you prepare the materials; if not, you lecture."
Sometimes showing a film is in the same category.
condemnation of these teaching aids is not the intent of this paper. They
make an excellent supplement to the live material, but they are not the live
material. Too many of us are prone to teach the aid and not the plant. After
having an N.S.F. class see "exploding" fern sporangia, fern spores, various
ages of live prothalli, the rupturing antheridia with their swimming sperms,
various sizes of developing embryos attached to the prothalli and mature fern
plants, a student remarked, "I have taught the life history of ferns for ten
years, and this is the first time I have ever seen any of it. Now I understand
what is happening." Apparently that teacher was teaching only aids.
thing that is most disturbing to me is the intended or suggested follow-up
reaction of students who say, "This is the best course I ever had in college."
They had lived through a course with much plant material and many live experiments.
They enjoyed observing, comparing, dissecting, smelling, and even tasting
plants. They had been prodded to explain how, why, when, and where, and had
been delighted in the experience. So they asked, "Why don't you write a book?"
or "I have enough notes in my notebook to write a book." Do they realize what
they are saying? They want to fix by publishing, or having published, the
interesting observations or data they enjoyed collecting. Instead of having
their students struggle through the how, why, when, and where, they want to
tell them. Maybe it is the same motive many of us have in taking pictures.
It was a pleasing experience or scene, and we want to take it with us. A picture
is a way to remember. And so- their students are going to be told about their
experience and be denied having the experience. One can be sure of his classroom
procedure if he uses pictures, models, charts, and printed pages. The variables
associated with live material can be eliminated if such helps are used. Besides,
a laboratory can become quite cluttered if one uses fresh material. So botany
be-comes a course in classroom helps and movies. Is that what has happened
to many general botany courses?

,FROM THE EDITOR
I take this opportunity to thank Dr. Bill Stern for the superb job he did
as "Temporary Editor." One might assume that this was very easy for Bill to
do since he him-self had been Editor for several years preceding my cur-rent
term. But it must be remembered that all of the machinery of the editor's
office had been moved across the continent, and in consequence Bill had to
carry out what to me are routine local communications through the indirect
procedures of mail correspondence. Among other problems was his need to "scrounge"
for appropriate copy to fill our usual eight pages at quarterly intervals.
This continues to be my problem, yet surely the botanists of America are engaged
in many activities that deserve to be brought to the attention of our readers.
May I suggest that each department chairman appoint one member of his faculty
(or himself) to see that information about important and significant advances
in botanical thought and education as well as notes concerning personnel changes
in his department are sent in at regular intervals for publication in the

sudden and unexpected death of Professor Robert M. Page on May 17, 1968, came
as a profound shock to his many friends and to the national botanical community.
His nimble wit, his geniality, and his ready willingness to give of his time
and effort to anyone in need or to any good scientific, social, or political
cause will be sorely missed.
a native of Pasadena, California, entered Harvard College in 1937 on a National
Scholarship and graduated Magna Cunt Laude with his class in 1941. As an under-graduate,
Page, a tall, lanky ectomorph, was a member of the Yacht Club, did some intramural
rowing, and was a moving spirit of the Biological Club (Secretary in his third
year). The academic year following his graduation he spent as a graduate student
with JRR at Indiana University, from whence he was inducted into the United
States Army. His tour of duty in the armed forces was mostly spent at Camp
Dietrick, Maryland, in the Chemical Warfare Service. In 1944 he married Dr.
Virginia Michaud, a former fellow graduate student at Indiana University.
Upon his discharge from the army in 1945, he resumed his graduate work as
a predoctoral National Institutes of Health Fellow at Harvard under the sponsorship
of Prof. Wm. H. Weston. The Ph.D. was earned in 1948 with the doctoral dissertation
entitled, "Studies on the Metabolism and Conservation of the Dermatophytes,"
a work largely concerned with the degradation of keratin by pathogenic fungi.
Assistant Professor of Biology at Stanford University in 1948, he was promoted
to Associate Professor in 1954 and to Professor in 1963. He remained in residence
at Stanford throughout this period except for a year's leave at Harvard in
a sophomore at Harvard, Page took Weston's course in Cryptogamic Botany and
was thereafter never quite the same. At this time early in his career, he
developed an infectious affection for lower plants in general and for the
dung-inhabiting phycomycetous fungi in particular that dictated the course
of his own later work and was transmitted to several generations of Stanford
students. His own enthusiasm for the subject material of biology, his ability
for concise organization of information, his whimsical wit, and his natural
love of people—particularly young people—contributed critically
to his unusual effectiveness as a teacher. For many years, he taught the elementary
botany course, and a large number of Stanford students learned, often to their
surprise, that plants are interesting; that the interest was genuine was reflected
in continuing heavy enrollments in the advanced botanical courses.
research subsequent to his doctoral work primarily concerned various aspects
of the physiology and over-all biology of two members of the Mucorales, Phycomyces
and Pilobolus, with particular attention focused on photobiological phenomena.
With more than a little touch of the puritan, Page wanted to be beholden neither
to man nor to benevolent agencies: applications for research grants and fellowships
were accordingly rare and exceedingly modest. His research was thus often
done with equipment and
that ranged from obsolete to primitive. He was a wizard in the fabrication
from scavenged bits and pieces of jury-rigged devices for specific purposes,
and it was truly remarkable how well they ultimately worked. A case in point:
the first picture of the "lift-off" of a sporangium of Pilobolus on its jet
of liquid was taken with a set-up containing electronic elements scrounged
from waste barrels along the streets near the laboratory. He did, however,
properly appreciate and upon occasion made use of the elegant equipment of
his colleagues: the measurement of the muzzle-velocity of a Pilobolus-sporangium
was made in collaboration with a very well-instrumented neurophysiologist-colleague.
publications were not voluminous, but his contributions were very significant.
He had the happy facility of recognizing the central feature of a problem
and of designing elegant but simple experiments to clarify specific points
and to elucidate basic principles. His research papers, though relatively
few, presented the results of meticulously careful work in models of clear,
concise exposition, and his several reviews reflected an authoritative understanding
of the conceptual and factual development and status of the subjects.
achievements as a scientist, however, were no more critical in earning him
the wide affection and respect that he enjoyed than was his warm personality.
High good wit and humor, unstinting work devoted to worthy causes—local
and national committees and panels—and an extra-ordinarily acute awareness
of the sensibilities and needs of others combined to make of Bob a rare, precious
person who has enriched the lives of so many students, colleagues, and friends.
As one of us remarked upon hearing of his death, "I would feel far better
about my own life if I thought someone feels about me the way I feel about

primary aim of this paperback monograph is to describe and discuss the American
species of linden. The study is based principally upon morphology, taxonomy,
and ecology, that is, upon the study of the structure of pre-served specimens
in the herbarium, and observation and collection of specimens from living
trees in the field. Although there are only four species of Tilia in America
as contrasted with the relatively complex Tilia flora of east-ern Asia, the
latter has been more clearly defined than its simpler counterpart in eastern
North America. Author Jones covers the voluminous literature and extensive
lists of synonyms in scholarly fashion; specimen citations from all portions
of North America attest to the painstaking scrutiny applied to problems. A
true, synthetic mono-graph, the author covers all pertinent aspects of his
study including sections on morphology, chromosomes, hybrids, properties and
uses, propagation, age and size, geographical distribution, fossil lindens,
origin and evolution, and,
course, keys to species and descriptions of taxa. With the name linden so
closely associated with the name of Linnaeus, the introductory section on
names makes fascinating reading for those so inclined.

4th edition of Dr. Smith's book represents a contribution to Methuen's series
of Monographs on Biological Subjects. The text of this 4th edition has been
completely rewritten and attempts to present the reader with an over-all synopsis
of the field of plant virology. Need-less to say, this is difficult in view
of the amount of in-formation available but the author does present a very
interesting, concise, readable review of the subject matter. This book will
be very useful for teachers of plant virology at the introductory level and
for scientists in allied fields who wish to have a brief exposure to plant
author briefly exposes the reader to the classical as well as the modern approaches
to plant virology. After a short introduction, the symptoms and physiology
of virus-infected plants are discussed followed by chapters on the isolation,
purification, morphology, structure, and chemical nature of the virus particle.
The biological aspects of plant virology are included in chapters on infection,
replication, transmission, assay, serology, tissue and cell culture, method
of testing, and, finally, a chapter on nomenclature, classification, and control.
some chapters, especially those dealing with the chemistry and replication
of viruses, the author might have considered deleting certain chapters thus
allowing for a more detailed coverage of the recent modern aspects of plant

a Symposium on Insect Viruses held in conjunction with the 67th Annual Meeting
of the American Society for Microbiology in New York, N.Y. on 30 April-4 May
1967. The papers are well prepared and present a concise survey of the viruses
that affect insects. Gordon R. Stairs' paper presents the "Inclusion-Type
Insect Viruses" and C. Vago covers the "Non-Inclusion Virus Diseases." Roy
W. Chamberlain prepared the chapter on the "Arboviruses, the Arthropod-Borne
Animal Viruses," and Robert Seecof discusses "The Sigma Virus Infection of
Drosophila melanogaster." The "Plant Pathogenic Viruses in Insects" is presented
by Karl Maramorosch. James C. Vaughn gives " A Review of the Use of Insect

of the three segments of this volume represents a textbook, complete with
illustrations, on the subjects of paleobotany, genetics, and physiology. The
segment on genetics was authored by Kenneth Lewis. The contents for each volume
arc collected in three separate lists at the beginning of the volume; the
indices are collected in three lists at the end of the book.
paleobotanical section has a very brief introduction and it is apparent that
the reader is expected to know considerable about the means of fossilization,
the geologic processes, techniques of study, and the geological column. A
logical division into geological eras and their subunits provides a framework
for the discussion of the fossil plants extant during these time periods.
Each major time period is introduced with a description of major features
and events. Within each time period, plants are considered taxonomically,
i.e., from the lower taxa to the higher taxa. Although there are continuous
references to the literature, no bibliographic material is included, an unfortunate
circumstance which somewhat limits the usefulness of this section to beginning
Lewis' section on genetics is not aimed at the neophyte; rather, he presupposes
some basic knowledge of genetics on the part of his readers. The elements
of nuclear division are treated succinctly and the experiments of Mendel are
set forth clearly. Independent assortment is outlined and contrasted with
linkage. Meiosis is described in some detail including chiasmata and crossing
over. A considerable section is devoted to the statistical analyses of genetic
ratios and chromosome mapping. Sex chromosomes and sex linkage, bases of variation,
ploidy, mutations and natural selection, breeding systems, speciation, and
gene action complete the "physical" aspects of genetics. The final pages are
directed to "chemical" genetics including a discussion of the nucleic acids
and their role in replication and transfer of genetic information. A brief
list of books for further reading concludes this section.
is discussed under headings of water supply, metabolism, and growth and reactivity.
In contradistinction to the sections on paleobotany and genetics, physiology
seems to begin at a more rudimentary level, and the simple processes of electron
pairing and hydrogen bonding are explained at the outset as are the phenomena
of solution and ionization. Interestingly, a more detailed discussion of the
nucleic acids occurs in this section than in the section on genetics. The
author apologizes in the preface for his not being a "professed physiologist";
nevertheless, he has carried off this difficult task of summary writing with
clarity and simplicity. Here again, though, there are no literature citations
for further reading.
seems that these "textbooks" are not designed for the novice; rather, they
serve well to reacquaint the professional botanist with long-forgotten subject
material. The graduate student seeking a concise introduction into a new field
will find these selections excellent reading. The researcher, alas, will be
left wondering, "Where do I go now?"

who would even attempt a chronology of a science which had its beginnings
almost 4,000 years ago is highly deserving of accolades. Professor H. H. Whetzel
was the last to accomplish this when he published his "Outline of the History
of Phytopathology" in 1918. Professor Parris has attempted to update the work
of Whetzel by reviewing chronologically the important developments in plant
pathology that have occurred beginning 2,000 BC when reference was first made
to the use of a fungicide to control field and storage pests up to the release
of Bawden's revised edition of Plant Viruses and Virus Diseases in 1964. In
places, the information is sketchy; however, this is to be expected and where
additional information is desired, the reader can refer to the textbooks and
review articles that Parris used as his source of information.
author also includes an index of author and subject matter with the year of
occurrence. Easy to read, and reasonably priced, this book can be recommended
both to beginners and to advanced workers in the field interested in the events
in the evolution of plant pathology as a science.

is an elementary text dealing primarily with nematodes parasitic on plants.
Four chapters on biology, structure, and host-parasite relations of nematodes
are followed by 16 brief chapters covering individual genera of plant-parasitic
nematodes. The book concludes with a chapter on "nonparasitic soil nematodes"
and three chapters on nematode control. This book would be suitable for use
in an introductory undergraduate course in plant nematology.
