lege of Pharmacy, class of 1932. This lecture dealt with the 
methods by which pharmacists recognize drugs macroscopically 
and microscopically, the preparation of drugs, tinctures, fluidex- 
tracts, etc., and the biological and chemical methods of standardiza- 
tion of important drugs. 
It would be a feature of distinct advantage, not only to these 
classes but also to the general public, if at some time in the near 
future a small area such as the triangular plot just west of the 
Rose Garden could be devoted exclusively to medicinal plants. 
Such collections are an important and integral part of many Euro- 
pean botanic gardens. 
The total number of persons registered in the adult courses for 
1933 was 823, as against 908 last year. The figures for the last 
few years are as follows: *

FLower Days 
The flower days were continued as usual this year. These are 
informal occasions at which the members of the Garden and their 
friends are afforded an opportunity to see, under guidance, those 
collections which are of outstanding interest, and to view them 
when they are at the height of their flowering period. Several 
days in succession were devoted to the Japanese Iris, under the 
guidance of Dr. Reed. This was a departure from the usual cus- 
tom, and has the advantage that it offers additional opportunity to 
those who might not be able to attend if only a single day is se- 
lected. The exercises were well attended, averaging about 150 
for each occasion. The social arrangements were in charge oi 
the Woman’s Auxiliary, assisted by the young women of the Gar- 
den personnel. We would like to avail ourselves of this oppor- 
tunity to acknowledge our indebtedness to both of these groups 
* These figures differ from those of previous reports because registration 
in the full-year courses is here counted according to the calendar year rather 
than the school year as formerly.
