to look at, if he still uses the microscope. And if you happen to know some young man or woman, preferably with some knowledge of botany, who would like to make some extra money, I should be glad to pay $50.00 (U.S.) for say 25 collections of desmid material from good habitats similar to Las Toscas. I used to subscribe to Mikrokosmos, but apparently they suspended publication during the war, and I have not received it since about 1941 or 42. Is it still published by Franckh'sche Verlagshandlung in Stuttgart? With many thanks, I am, Yours sincerely,

RUTGERS UNIVERSITY NEW BRUNSWICK, NEW JERSEY DEPARTMENT OF BOTANY May 6 1935 Professor John M. Fogg,Jr. Department of Botany University of Pennsylvania Philadelphia, Pennsylvania Dear Doctor Fogg: In connection with a piece of morphological work which constitutes the problem which I have set one of our graduate students, we are in need of material for the study of the floral axis of as many species of Magnolia as possible. Around here we can of course get virginiana, stellata, and Japanese forms such as kobus, but so far we have not secured grandiflora, umbrella and others of our southern species. Remembering you …

meters 0.5 m., 0.1 m., etc. This is to reinforce the other information, and is quite helpful when examining the herbarium specimen. This may be eliminated if you are willing to record height, and branching pattern in detail as part of your field notes. I have found the photograph very useful, however, and invariably make an exposure to accompany any and all specimens of my own. Enclosed is a photo of one of my earlier photo-backboards. I modified this later, but don't have a spare photo to send you. The herbarium specimen is also the document I used to keep information together concerning whatever analyses are ma …

La Biblioteca de la SMM recibió esta magnífica obra sobre los hongos de la Península Ibérica. En ella se ilustran y describen 800 especies de macromicetos. Las fotografías de excelente calidad y la información relativa a la fenología, co mestibilidad, descripción macroscópica y de las esporas se conjuntan para formar un tratado enciclopédico de alto valor para el estudioso de la Micología. Sin duda, una obra que puede ser de gran utilidad para el conocimiento y comprensión de la micoflora mexicana ya que muchas de las especies ilustradas en ella son abundantes en los bosques de nuestro país. Deacon, J.W., 1987. I …

January 15, 1964 Copy Dr B. Lowy Department of Botany Louisiana State University BATON ROUGE, Louis. U.S.A. Dear Dr Lowy: I have taken the liberty of sending you a box of 25 selected microscopic slides of fungi which you may perhaps be able to use in your courses. In return I shall greatly appreciate having coloured transparencies (35 mm) of some mycological and plant pathological specimens of your region. If such an exchange proves useful, we can perhaps extend it further in the future. Thanking you for whatever consideration you may be able to give to this request: Yours sincerely P. Maheshwari Professor of Bot …

… ans. They cost me considerably more than I could have bought full-size photoprints from some of the large libraries, like that of the Dept. of Agriculture in Washington, which has an enormous collection of botanical works of all kinds. However, I recently stumped them with a request from Ruzicka for copies of the plates in Gutowski's 'Flora glonow okolicz Tarnopol', which they did not possess. I am getting it from the Farlow Library of Harvard University. These photoprints cost only 10 cents per page, far less than the New Orleans shops charge for enlarging a microfilm, or for making direct photostats. I have acq …

… much richer, and more diversified. Our previous wrong outlook was simply due to the fact that warmer regions had been neglected, as I think you have amply proved. To give you an idea of what phase-contrast microscopy can do for some marine diatoms with hyaline setae, I am enclosing three photographs of Chaetoceros, plus two of Coscinodiscus (one of which was taken with the oil-immersion objective) and one of Micrasterias. Recently I have had 8 x 10 enlargements made of these pictures and several others (taken with a Contax on 35 mm. film), and I presently have an exhibition of them in one of the University halls. …

I plan to examine one or two sporangia per specimen with the Scanning Electron Microscope in order to determine the nature of the spore wall ornamentation in the pink- and white-spored forms of this taxon.

of these varied microorganisms are grouped together in the Palynology Section. I would also recommend inclusion of morphologic studies of extant spores and pollen which provide taxonomic and/or phylogenetic information. This would include descriptions based on both transmission electron microscopy and the newer scanning electron microscopy, as well as the more conventional light microscope investigations.

Rogers Department of Botany, University of Colorado, Boulder, Colorado. Dear Dr. Rogers; I am very much interested in your excellent works using a computer in taxonomy and I was also very much impressed by your speeches at Missouri Botanical Garden annual Symposium and at the herbarium. I was working on cytotaxonomy of Salix with Dr. Argus while I was in Canada and I would like to study more about your works and your methodology. I would appreciate it very much if you could send …

Two other people who might be able to help you are: Dr. Rogers McVaugh, University of Michigan, Ann Arbor, Michigan, who is interested in the history of botanical exploration in Mexico; and Mrs. Ida Langman, Academy of Natural Sciences, Philadelphia, Pennsylvania, who has been making bibliographic studies relating to Mexican botany. I do not know if their studies have dealt with San Luis Potosi, however. I will turn your letter over to Dr. Sohns, in case he has any of the information you are seeking. Thank you for your interest in Nissolia. I will be glad to se …

Wie können Sie dabei Vorsicht fassen, als Material in die Neuen Arten Reprographie zu verwenden bei dem Umstand, dass es sich um das Leben und die Entwicklung der Pflanzen handelt? Ich glaube, es ist besser für die Abhandlung, wenn man sich auf die Beschreibung der Pflanzen beschränkt, die man selbst beobachtet hat.

Part II 118 copies THE ANATOMY AND PHYSIOLOGY OF SEED PLANTS Up to date Last spring our studies dealt wholly with macroscopic features of the seed plants. Now we begin to go into details carrying our investigation of living plants as far as modern instruments will permit. After learning how the plant organs are put together (Anatomy, Histology and Cytology) we shall then logically take up their various activities (Physiology). The course will end with a very brief resume of the various kinds of plants. The Microscopic Anatomy of the Plant (Histology and Cytology) You have seen that plants and plant parts differ m …
