There is no danger of transmission here in the garden 
because the ova must pass through a particular secondary 
host before attaining a stage in its Ufe cycle where it 
can again infest the cat or man; and it is extremely 
unlikely that such a secondary host is living in any 
proximity to the carnivora house. 
Tumors. 
We mention the following tumors: — 
Common Opossum (No. 4692). A small adenoma at 
the pyloric ring of the stomach which is perhaps analogous 
to polyposis gastrica of human beings. 
Richardson's Kangaroo Rat (No. 4693). A large 
sarcoma springing from the base of the urinary bladder. 
Crested Pigeon (No. 4738). Multiple chondromata of 
breast bone and pelvis. These were not, as commonly 
seen before, at the articular margins and are therefore 
more likely bona fide neoplasms than the former. 
Common Opossum (No. 4763). Adeno carcinoma of 
mammary gland. This almost filled the marsupium at 
autopsy and yet only two months before it had in addi- 
tion accommodated four or five well-developed young, 
i, e,, well enough developed to emerge and make excursions 
from the mother. 
Common Raccoon (No. 4817). Fetal adenoma of 
thyroid. This was as large as a bantam's egg. 
Binturong (No. 4844). Primary carcinoma of lung. 
Grossly it occurred as several nodules, the largest the 
size of a cherry. Sections showed adeno-carcinoma. Its 
origin therefore is most likely from the bronchi. 
Gray Parrot (No. 4846). Lymphosarcoma of liver 
about the size of a pea. 
Himalayan Thar (No. 4856). Osteoma of rib. 
Gambel's Quail (No. 4870). Papilloma of pro ventricle. 
A picturesque spherical polyp the size of a sago grain. 
Towhee (No. 4962). Lipoma of anterior abdominal 
wall the size of a small marble. 
Red Kangaroo (No. 4973). Carcinoma of lung.
