AB O U T a quarter of an inch below the ^roftat^e or prof. 
tate glands, f^ig. i. Plate XII. Mr. Comper found two other 
fmall glands GG, placed on each fide the Urethra F, a 
jitde above the bulb of its cavernous body 1 5 thefe glands 
are of a depreft oval figure, about the fize of a fmall French 
bean : After that thele parts of the Alufculus accelerator 
L L are removed, which pafs over thele glands, you may 
feel them placed like two hard bodies on each fide the 
Urethra J they incline to a yellowifh colour, like that of the 
^Projiat^ ; their excretory du^s appear on their internal furface 
Fig. 2. A /?, next the inner membrane of the Urethra C, 
whence they defcend about half an inch in lengdi, before 
they grow lefs, and pierce that membrane obliquely at their 
opening into the Urethra D, in which they diicharge their 
fepararcd liquor: After opening the upper part of the 
Urethra towards the 'Dorfum 'FeuiSy and expanding its inner 
membrane, if you comprefs thefe glands, you may fee a liquor 
iflue from two diftindl orifices, which is very tranfparent and 
tenacious 3 thefe two orifices open into the Urethra^ jult below 
its bending under the OJfa Fubis in the Ferinaian: The me- 
chanifm of nature is very extraordinary in thus placing thefe 
glands and their excretory dufls, fince upon the erection of 
the 'PeniSy and the diftenfion of the bulb of the cavernous body 
of the Unt bra, they %YQ thereby neceflarily comprels'd, and 
the liquor contained in their excretory dufls, forced thro' their 
two orifices, into the cavity of the Urethra -^ bcfides this, that 
part of the Ahf cuius accelerator mentioned above, which paf- 
fesover thefe glands, contributes to this compreffion : It feems 
requifite fuch agents ihould confpire in comprcfTing thefe or- 
gans, firce the liquor they feparate is {^o very'tenacious, which 
confidence is ablolutely necefiary for theule.s it is employed in: 
The main defign of nature in framing thefe glands, feems to 
refpecl the grand work of generation, which will be more evi- 
dent, if we examine the analogous organs in other animals 5 
in rats thefe glands are remarkably large, and are fo fituated 
that, upon the ere£lion of the Penis, they are comprefTed by 
its turgency and the appofirion of the OffaPubis-^ the like may 
be obferved in other animals, particularly in hedge-hogs; boars 
have thefe glands very large, and the matter they feparate is 
more
