Several small groups of birds and mammals died within 
a few weeks of arrival and this doubtless swelled our 
death list to some extent. There have been no epizootic 
outbreaks nor any large groups whose loss was due to 
any one discoverable factor like poor food. A number 
of finches were subjected to postmortem and found to 
have whole white millet seeds in their intestines, this 
being the only discoverable cause of death. Investigation 
revealed that mice ate the canary seed in the pans during 
the night, leaving only the millet which the hungry birds 
consumed whole. Small birds can take a few millet and 
crack them when eating leasurely but apparently not 
when hungry. When the millet was removed at night 
the trouble ceased. 
Dispite the high mortality few important animals were 
lost, only the following demanding special comment. A 
very fine Chacma Baboon was ill when received; an 
existing nephritis was whipped into an acute exacerba- 
tion by the injection of tuberculin; this is the only case 
of this sort since our test dosage passed the experimental 
stage. A fine young Brazilian ocelot died from the 
anemia of uncinariasis. The Hyacinthine Macaw, which 
has been in the garden 26 years, died early in 1920 from 
intestinal inflammation. It is noteworthy in connection 
with the well known age to which these birds survive, 
that no marked evidences of senility were observed. 
There were mild chronic lesions of the liver and kidney 
but arteriosclerotic lesions were conspicuous by their 
absence. 
A Mongolian wild horse was born here in April 1919 
but lived only a few days, dying from intestinal obstruc- 
tion due to volvulus. This is unfortunate because these 
beasts are becoming scarce and rarely breed in captivity. 
A fine specimen of the rare woolly monkey was acci- 
dentally exposed to some spider monkeys with amebic 
dysentery and succumbed to this infection. A Ceylon 
entellus monkey, a species not exhibited in the garden 
for many years, died of peritonitis following perforation
