personal interest in my studies, and assistance which has 
been constructive and stimulating. Whether or not this 
present work prove useful to the extent that is hoped, the 
results from the Laboratory are such as to make the 
scientific world debtor to this gentleman. 
It is a duty, and a pleasant one, to record, though 
unfortunately in memoriam, my association with Arthur 
Erwin Brown, A.M., Sc.D., Ph.D., C.M.L.Z.S., for many 
years the Secretary of the Society and Executive Officer 
of the Garden. Doctor Brown as teacher was ever ready 
to help in the broad subject of biology, and I am proud to 
recall that he guided me also as a friend. 
The first director of the Laboratory was Courtland Y. 
"White, A.M., M.D., who served from 1901 to 1906, retiring 
then to accept a position in the City Laboratory. The 
foundation of the recording system is still in use essen- 
tially unchanged from his plan, and is a credit to his fore- 
sight. Our clerk and technician. Miss Harriet M. Phelps, 
has served the Garden faithfully and well since 1906. The 
condition of the museum is very much due to her interest 
and watchfulness. Thanks and appreciation for her work 
are felt by every one, the author most of all. Dr. F. D. 
Weidman has been our first assistant since 1911, and his 
work on parasitology has been of the greatest value, 
practically and scientifically. It is to be hoped that we 
shall be able to retain him indefinitely. Dr. E. P. Corson- 
White has in recent years taken an assistant position 
with us, armed for the work with a thorough knowledge of 
applied organic chemistry and immunology, and has 
already obtained useful results.
