Pasteur-Mendel Celebration 
In recognition of the hundredth anniversary of the births of 
Pasteur and Mendel, informal exercises were held at the Labora- 
tory Building on April 19. Dr. O. E. White, Curator of Plant 
Breeding, spoke on the life and work of Mendel; and Dr. G. M. 
Reed, Curator of Plant Pathology, reviewed Pasteur’s career. 
In connection with the celebration, exhibits of apparatus, plant 
material, photographs, and original publications and books illus- 
trating the lives and discoveries of these pioneers in science were 
installed in the Library and in the central rotunda of the Labora- 
tory Building. The exercises were well attended, mainly by high 
school pupils and biology teachers. 
Study Material for High Schools 
This field of service has grown by leaps and bounds. During 1921 
there were only 27 requests from the various high schools for 
materials, such as agar for the study of bacteria and molds, for 
Spirogyra, Elodea, fern prothallia, etc. In 1922, there were 48 
requests; in 1923, IIO. 
Already, in 1922, the demands on my time were so great that I 
could no longer properly carry on this branch of the work single 
handed, and until a full-time assistant could be appointed Mrs. 
Hill acted as part-time assistant. We were fortunate in securing 
the services of Miss Charlotte S. Young, for many years con- 
nected with the Biology Department of Erasmus Hall High School, 
to assist in the preparation of this study material and also in 
other activities of the department. Since the date of Miss Young’s 
appointment, September 1, 1923, we have received 76 requests for 
material—or an average of nearly one a day—and for this period 
more than in all the two years of 1921 and 1922. For the whole 
year of 1923 the requests have been more than double the number 
(48) of the previous year. Six hundred sixty-four petri dishes 
(as against 358 last year) and 12 flasks of agar were filled for 
the schools. We have supplied every high school in the Borough 
of Brooklyn as well as some in Queens and Manhattan with 
study material of some sort.
