THE MALE GENITALIA 315 
pale gray-pink and rather firm. Histologically it is about 
equally glandular and fibrous. In this case the cellular 
activity is undoubted, and one must consider it adenom- 
atous. The cause of death was enteritis, being perhaps 
more serious in the presence of the urethral obstruction. 
The seminal vesicles are distended to 7 x 2 cm. with a thick boiled- 
starch-like material. Wall and mucosa are negative. Prostate large, 
tense and injected. Its cut surface is pale purple, homogeneous; 
character of fluid is normal although excessive. Urethra is occupied 
by a cast of rather tenacious starch-like matter which begins at neck of 
bladder and runs almost to meatus. Openings of excretory ducts are 
prominent. Mucosa and submucosa of urethra are deep purple and the 
former seems to be slightly opaque as if covered with desquamated 
epithelium. Testes and epididymes seem normal. Vasa deferentia are 
slightly distended with excess of normally turbid fluid. Microscopical 
section shows hyperplastic epithelial condition with accumulation of 
droplets of hyaline matter but there is no amyloid deposit. In places 
it is possible to see a hyperplastic and loosened epithelium with nuclei 
becoming vacuolated, and the whole being cast off. Less granular free 
globules suggest that this is the method of origin of the hyaline globules 
free in the acini. The picture is one of papillary adenoma. In some 
places there is surely reduplication of the lining cells. Connective 
tissue is deeply staining, compact and with adult nuclei. Growth is not 
very vascular. There are no corpora amylacea. 
A case of tuberculous prostatitis and seminal vesic- 
ulitis was seen in a Japanese Macaque {Macaciis fusca- 
tus). Judging by the advanced stage of these lesions and 
their more recent character in other viscera, the disease 
was suspected as pelvic in origin, possibly due to infection 
by a thermometer. Whether or not such be the case cannot 
be established, but at all events, separate thermometers 
kept in carbolated vaseline were employed after this 
death. The females caged with this animal did not de- 
velop tuberculosis of the pelvic organs.
