House was enclosed with a glass front and fitted with heating 
and ventilating appliances for their reception. The natural 
delicacy of constitution, common to all of the monkey tribe, pre- 
disposing them to pulmonary diseases and disorders of the ali- 
mentary system, is strongly marked in the higher members of 
the order, and renders it extremely difficult to keep them alive 
in the close confinement necessary under our rigorous climate. 
It was not anticipated, therefore, that these animals would long 
remain inmates of the Garden, and this expectation was realized 
by the death of the female, in December, of gastritis, resulting, 
without doubt, from a severe cold, and the loss of the remaining 
one from a similar disease about six weeks later. They proved 
to be exceedingly interesting, and Avere usually surrounded by 
large numbers of visitors. 
Two lizards, from the south-western borders of the United 
States (Holbrookia maculata and Crotaphytus coUaris), presented 
by Professor E. T>. Cope ; a specimen of the Ring-necked Snake 
{JDiadophis punctatus), found in the eastern portion of the United 
States ; a Scarlet Ibis [Ihis rubra), from the Amazon river, and 
a pair of Wild Boars {Sus scrofa), from northern Africa, pre- 
sented by Felix A. Mathews, Esq., United States Consul- 
General at Tangier, all of which were new to the collection, 
were also received during the month. 
June. 
Several collections of snakes were received from friends of the 
Society in Ohio and Indiana in the month of June. These be- 
longed mostly to the genera Heterodon, Ophibolus, Coluber, 
Tropidonotus, JEutcenia, Bascanion, and Cemophora, and con- 
tained a number of species which had not previously been ex- 
hibited. A buck of the white variety of the European Fallow 
Deer (Dama vulgaris) was bred in the Garden, as well as a fawn 
of the Mule Deer [Cervus macrotis), from the western United 
States — this species never before having bred in the menagerie. 
July. 
These births were shortly followed in July by another fawn 
of the latter species, with several young Virginia Deer ( Cervus 
virginianus), a Capromys ( Capromys pilorides), and four Beaver 
{Castor fiber canadensis). 
Two Tortoises {Testudo tabulata), from Surinam, were also 
received from Dr. Constantine Hering.
