of the human prostate Gland. 
This appearance of a bridle is more or less met with in all 
the cases, in which the nipple-formed process occurs, but in 
so much smaller a degree, and not continued beyond the caput 
gallinaginis, that it never before led me to pay attention to it. 
To satisfy myself how this tumour was formed, it became 
necessary to examine the prostate gland in its natural state ; 
and ascertain whether there is any part sufficiently detached 
to move independent of the rest of the gland, and explain the 
appearances which had been met with in this particular case. 
My professional avocations not affording time to make the 
dissections requisite for this purpose, Mr. Brodie, Demon- 
strator of Anatomy to Mr. Wilson, Teacher of Anatomy, in 
Windmill-street, whose knowledge of the subject fitted him 
for the task, and whose zeal for the improvement of his pro- 
fession made him willingly undertake it, gave me his assist- 
ance, and took the whole of that labour on himself. 
While dissecting the parts for this purpose, the urinary 
bladder was distended with water, and the surfaces of the 
prostate gland, vesiculas seminales, and vasa deferentia, were 
fairly exposed. This being done, the vasa deferentia, and ve- 
siculae seminales were carefully dissected off from the bladder, 
without removing any other part. These were turned down 
upon the body of the prostate gland. An accurate dissection 
was then made of the circumference of the two posterior por- 
tions of the prostate gland, and the space between them was 
particularly examined. In doing this a small rounded sub- 
stance was discovered, so much detached that it seemed a 
distinct gland, and so nearly resembling Cowper’s glands in 
size and shape, as they appeared in the same subject, in which 
they were unusually large, that it appeared to be a gland of
