monkeys. Eleven rhesus macaques and one pigtail 
macaque were together in a large cage. In individual 
cages there were two Barbary apes, a Grivet monkey, 
a yellow baboon, a Lion-tailed macaque, and a Hainan 
Gibbon — the two latter having also been out all of the 
previous year. In each cage there was a shelter box 
filled with hay, in which the monkey could retire. Two 
Cape hyraces were also kept out all winter; one died 
the end of February, showing enteritis and congestion 
of the lungs. We consider it doubtful whether the cold 
caused this condition, which is not uncommon in Zoologi- 
cal Garden animals. The other hyrax is perfectly well. 
Two Cervinus kangaroos stayed out, with access to 
an unheated building. These kangaroos were pur- 
chased last fall in Hamburg, where they had been kept 
out during the two preceding winters. Johanna, the 
Chimpanzee, was taken outside for one or two hours 
every day during the winter, except when it rained or 
snowed. The temperatures of the buildings were allowed 
to fall to a lower degree than on any previous winter. 
An example of the temperatures may be taken from an 
observation on February 12th. The lowest tempera- 
ture during the night had been 1° above zero; at 2 
P. M. it was 13° above zero; at that time the tem- 
perature of the Carnivora house was 25°, of the Elephant 
house, in which were elephants, rhinoceros and hippo- 
potamuses, 38°, of the Giraffe house 39°, of the Monkey 
house 42°. The only warm houses were the Bird, 
Snake and small Mammal houses. 
All the monkeys in the Monkey house had free access 
to the open air through swinging doors, and often went 
out voluntarily during the coldest days. Except for 
slight frost-bite of the end of the tail of two monkeys, 
none of the animals have appeared to suffer in any way 
from the cold, and all that were exposed are now 
apparently in good health, and in remarkably good coat. 
Last spring an effort was made to obtain new mem- 
bers and, in response to a circular letter, eighty persons 
expressed their desire to be elected, of these, twenty-
