The death of the Hainan Gibbon resulted from a curious 
accident. This animal always wore a loose belt, an 
appliance necessary in holding him, and apparently 
without the slightest irritation or discomfort of any 
kind. Early in the morning of January 2d he was noticed 
to be bleeding from the region of the waist and his belt 
was removed, whereupon blood spurted from an abraded 
area in the right loin; death occurred (in a short time) 
apparently from the hemorrhage since no other sufficient 
cause was found elsewhere in the body. 
The white-crowned monkey, the very rare specimen 
we have had for four years, died frohi a toxemia in all 
probability dependent upon a chronic gastritis. The 
loss of the Phillipine spotted deer was due to tuberculosis 
of the lungs with cavatition, a rather unusual finding 
in deer. 
The Stanley crane died as a result of a toxemia seem- 
ingly due to some occult intestinal poisoning. It un- 
fortunately could not be fastened upon any article of 
diet; no other bird from this same enclosure died near the 
same time so that it did not look like food poisoning. 
A lioness was killed because of its failing condition, a 
sacrifice warranted by finding a chronic gastro-enteritis 
of a character from which no recovery was at all likely. 
Four bears have died — grizzlj^, sloth, polar, and Tibetan 
blue. The first was a very old specimen, in the collection 
twenty-six years and becoming so infirm that his end 
was hastened. He showed a gastro-enteritis and the 
fibrosis of age. The sloth bear died from an enteritis 
and hemorrhages in the stomach from recent erosions; 
he also had a recent naso-pharyngitis. The polar 
bear died from a complication of conditions, among 
which multiple tumors arising from the adrenal bodies 
and trichinae in the diaphragm were the most important. 
These worms will receive some comment by Dr. Weidman. 
The important Tibetan blue bear died of a choleriform 
enteritis and a hemorrhage in the thyroid gland. 
There was described in the 1916 report an apparently 
infectious or toxic epizootic among the waterfowl on the
