The following neoplasms have been observed during the 
year and the chief pathological features are given below. 
Undulated Grass Parrakeet. 
Glioma of brain with metastases in the liver. 
Green Winged Amazon. 
Tumor of kidney. This is a mass including the whole of the lowest 
lobe of the left kidney, about the size of the last phalanx of an adult male 
thumb. It is very firm and contains on section some minute white dots. 
On microscopical examination the kidney structure has largely dis- 
appeared, its place being taken by fibrous connective tissue. The whitish 
dots seen by the naked eye consist of irregularly round calcareous bodies 
somewhat concentrically zoned. These may be parasitic, but the pos- 
sibility of a fibrous tumor with concrements is the reason for the in- 
clusion of this tumor in this list. 
All-Green Parrakeet. 
Carcinoma Sarcomatoides of the pectoral muscle, left side. Four dif- 
ferent diagnoses have been given by competent men upon this tumor, 
as follows : Spindle-celled sarcoma ; carcinoma ; endothelioma ; and 
mixed carcinoma and sarcoma. The last is probably correct. The pre- 
dominating cell is large and pale, with a vesicular nucleus and prominent 
nucleolus. These run in bundles, but nests of the same cells can be dis- 
covered in which there is no probability of a transverse section. Again, 
distinct nests and acini can be found. The two arrangements just de- 
scribed predominate in different portions of the field and may possibly 
not be of the same type. The cells of the strictly carcinoma-like areas 
approach the typical epithelial form. 
Woolless Sheep. 
Carcinoma of the lung. (See separate description.) 
Wild Turkey. 
Papillary adeno-carcinoma of ovary. This is a papillary overgrowth 
in acinous arrangement. In some places the maUgnant type predom- 
inated, in others the adenomatous arrangement. Where the papillary 
type is prominent, some compression of the cells has occurred as if pearl 
formation were about to take place. 
Civet. 
Carcinoma of the lung. (See separate description.) 
Wood Ibis. 
Fibrous tumor formation on plantar surface of foot. (Suggestive of 
botryomycosis.) This consists of a fibrous stroma containing many 
eosinophiles, and proliferated connective tissue elements and some epi- 
thehal or endothelial nests, the latter probably from the lymph channels.
