ticed at the Philadelphia Zoological Gardens. This paper 
will appear in the Proceedings of the Congress. The article 
is accompanied by illustrative charts. 
Neoplasms were observed during the year in four of the 
cases following : 
1369. Rabhit-eared Bandicoot. 
Primary carcinoma of the lung. A squamous cell carcinoma present in the 
lang tissue near a bronchus and probably originating from its wall. The 
masses are in regulär acinus arrangement, suggesting an origin from the glands 
or from the epithelium of the alveoli. Thej'- enclose in them masses of necrotic 
nuclei and atypical mitotic figures. I am inclined to believe that this arises 
from the epithelium of a bronchus because it is confined to this neighborhood, 
and I think it can be seen spreading from the wall. 
1504 . Red Fox. 
Cystic adenoma of the bile ducts. A compound cystic adenoma of the bile 
ducts with moderate fibrous changes in the septa. The cysts are lined with 
a single layer of columnar epithelium. 
1338. Süver Pheasant. 
Fibro adenoma of intestinal rnucosa. The picture is that of an overgrowth 
of the glands of the duodenal rnucosa surrounded by a more or less clearly de- 
fined fibrous capsule and dhdded by a wide septum into two unequal parts. 
There is great tortuosity in the overgrowth of the gland acini, but at no point 
does there seem to be loss of relation between the epithelium and the basement 
membrane. The fibrous tissue is decidedly cellular, some of the cells being 
of a very early type. 
The following animals deserve some special mention. The Indian elephant 
“ Bolivar” contained a focus of tuberculosis in the upper half of the right supe- 
rior pulmonary lobe. This is interesting for the reason that he has been in 
the Gardens twenty-five years, in the same place. As a favorite with visitors 
he has been fed everything he would take, among which peanuts, broken by 
the teeth and pieces of bitten cake and pretzel were probably most numerous. 
He has thus been exposed to many chances of infection from human tubercu- 
losis. Efforts to isolate the tubercle bacilli from the lesions'were unsuccessful. 
The other cases are of scientific intere.st. Number 1416 is of value in re- 
cording another case of interstitial change in the liver apparently due to the 
toxines of tuberculosis emanating from the alimentary tract. 
1473 Caracal. 
Osteochondroma of nose. 
I 46 I. Indian Elephant. 
The noteworthy features about this animal are the presence of fibro-caseous 
tuberculosis, a moderate degree of myocarditis with brown atrophy, and 
parenchymatous nephritis, but no involvement of the aorta or otlier large 
vessels. The first mentioned process contained living tubercle bacilli, as shown 
by inoculation. There was evidence of long standing polyarthritis manifested 
by fluid accumulations in the joint cartilages, erosion of the cartilage and 
superficial layers of bone. There were, howevcr, no calcareous deposits. 
1484- Common Opossum. — Lymphatic Icukemia. 
The case here placed on record is one of lymphatic leukemia involving all 
the viscera. The predominating type of cell is large, with a narrow rim of
