352 DR. J. MURIE ON THE [May 26. 
remark regarding the organs in question in Ruminantia, when he 
says :—‘“‘It is far from improbable that they are both the one and 
the other—prostate and vesicule at orice.” 
The terminal enlargement of the vasa deferentia in the Prongbuck 
may correspond to what Leuckart figures as the Weberian organ, or 
uterus masculinus, in the Deer; and I ought further to observe that 
I did not detect that differentiation of the said organ from the vasa 
differentia which obtains in some he-Goats. 
The membranous portion of the urethra, 23 inches long, tapers at 
either end, but throughout is broadish, flattened, and possesses a 
deep longitudinal furrow below. The compressor urethra muscle 
(cu) is of great thickness, and its transverse fibres constitute a 
continuous arch, tucked into the under groove, from the neck of the 
bladder to the urethral bulb.

Cowper’s glands appear to be absent ; at least I could find no such 
enlarged prominent bodies as are found in the Chamois, Goat, and 
some other ruminants. The Prongbuck thus agrees with the Deer, 
where these glands are wanting. The place of these Cowperian 
bodies may, however, be supplied by a bilinear, long patch of minute
