samples are needed. The scanning electron microscope will be used primarily for illustration of selected samples. A high quality dissecting microscope is needed for the study of specimens and photomicrography of salient characters. BIOGRAPHICAL SKETCH OF THE PRINCIPAL INVESTIGATOR Gary J.

Scientific Plant Photography. by Theodor Philipp Haas, Ph.D., Botanist. I am a botanist, and especially a plant morphologist, interested mainly in the shape of plants and in the enormous multiplicity (Mannigfaltigkeit) which we can observe in the plant kingdom. I am studying this in roots, shoots and flowers, and I am teaching it in a college. I want to photograph in color what I see with the naked eye and by the use of a dissecting microscope, which reproduces subjects in three dimensions. For my work magnifications up to 150 x are sufficient. I must emphasize, I am by no means a professional photographer, but a …

Research I would be glad to train your research man in the current cytological techniques necessary for preparing genetic material for examination under the microscope. I could bring with me microscope preparations from my research collection for demonstration of basic cytogenetic phenomena and to give training in interpreting them under the microscope. In addition I could consult on your current genetic projects. For your information I am also enclosing a resume of my past services and contacts in South America since 1935. If you desired it would be possible for me to bring a variety of seeds and living plants t …

However, a first class research microscope for the genetic studies does not exist on the campus of Allegheny College. The highest powers available are the 900x of the student oil immersion lenses. Personnel: At present, the only investigator involved is the principal, Rogers.

In the case of annual plants, seeds will be collected for cultivation in the botanical garden at Ljubljana, and such seeds will also be collected from selected annual and perennial material for further biosystematic investigations in Boulder. In addition to the cytological investigations, critical species will also be compared in great detail during the winter, by aid of ordinary

… njoy the same world-wide recogni- tion which he himself had earlier achieved. Professor Bailey never regarded himself as an administrator but when he was asked during the years of World War II to study the botanical situation at Harvard, which was then in a chaotic state, and to make recommendations for its im- provement he gave up two years of his research to this formi- dable task. Because of his intimate knowledge of the history of Harvard's several botanical institutions and because of the confidence that all Harvard botanists had in him, he was able to persuade ten independent, virtually autonomous, botanica …

Would it be possible to obtain a good photographic print of this figure for use in my mycology lectures? Would it be in library books or would I be able to purchase a copy from someone? I would be most appreciative if you could help me. I am sending along some of my prints that may be of use to you. Sincerely, Stanley L. …

A Curator of Botanical Portraits is in charge of a program to develop this nucleus into a major repository of photographs of botanists. Photograph collections at other institutions, here and abroad, are being copied and added to this archive. Private collections, both of black and white prints and of color transparencies, are borrowed and photocopied. Biographical data on each botanist represented are compiled and added to …

und ich habe das Institut nicht mehr betreten dürfen. Nur den Garten und die Gewächshäuser standen mir bis ich weg zur Verfügung und auch photographieren konnte ich noch nach Belieben. Ich habe mehr als 600 Bilder von Pflanzen mitgebracht! Ich möchte Ihnen mit diesem Briefe meinen "Lebenslauf" senden. Ich wäre Ihnen sehr dankbar, falls Sie die Liebeswürdigkeit hätten, mir zu sagen, ob ich's Ihrer Meinung nach recht mache. Das, was ich eigentlich tun möchte, d.h., ein botanisches Museum, eine botanische Schausammlung, aufbauen das geht in Kriegszeiten nicht. Ich habe einen langen Artikel darüber geschrieben, habe …

… f information on the taxonomic categories combined with gross distribution data would make the compilation of checklists simple, the Center would soon make available a critical checklist of the North American flora, a very much needed project which, however, ought perhaps to be kept separate, although supported by the Center. Conclusions Such a Center would stimulate good floristic and monographic research by making available one central source whereby literature searches would be facilitated, duplication of effort reduced to a minimum and service to the field and its interrelated disciplines raised immeasurably.

… bit curious, so I wrote to Krieger about it. (But I cannot find his answer among his very many letters!) "Scottia mira Scott & Grönblad" - I don't know if it looks very nice? I shall ask my prof- essional botanical friends. (You could do the same). Of course I am most willing to cooperate with you as regards the Brazilian Algae. Try to forgive me that I do not always answer to your questions. I know there are more of them, but I have also made a list of questions which I am to answer. I would like to have something ready for print and I hope to have some "New and Interesting Desmids" ready for you - soon, I hope …

… olved. So I preferred to write popular-scientific articles which were paid and which were considered as very good. Now I think it is the time to turn to pure scientific problems. Dr. Pennell thinks that my botanical questions are very interesting, but I have also to bring the proof that I am able to handle them. When I can this than I will also get a grant of the Philosophical Society. Now, I will do my best! I think to start with the work and will continue my research during summer with my own means and then I will see how far I shall come under the present circumstances. I would appreciate it very much if you c …
