The study of the molds which grow on coffee beans and also 
upon commercial coffee essences was continued. Further work

was conducted regarding the formation and content of the coffee 
leaf glands. During the summer months of 1935 an experimental 
study was made of the effect of the coffee (Coffea arabica 1...) seed 
alkaloid, caffeine; and, of the tobacco (Nicotiana tabacum L..) leaf 
alkaloid, nicotine, upon the action of the smooth muscle of the 
intestine. This research was begun at the Marine Biological 
Laboratory, Woods Hole, Massachusetts.

PPORI OF THE CURATOR Or PUBLIC 
INSTRUCTION FOR 1935 
GARDEN ATTENDANCE 
We take, naturally, a great deal of satisfaction in reviewing the 
large increase in attendance during the past year. This has been 
manifested not only in the much larger number of people visiting 

the grounds and conservatories, but in the increased attendance in 
the classes of instruction, both for children and for adults. 
Grounds.—The total attendance on the grounds, as recorded by 
the turnstiles at the five entrance gates, was 1,624,865, a new vearly 
record. The 1934 attendance, also the largest on record up to 
that time, was 1,352,407. The 1935 figure exceeded this by 272,- 
458, an increase of slightly over 20 per cent. The attendance 
during seven particular months much exceeded all previous records 
for the same months, as follows:
