dion of the Sphinder Mufcle of the Bladder is (ufficr 
cient to expel any remains of Urine from that pafTage. 
The Ufe of the Glands (\ have now Deicribed) is 
twofold ; firfl: on the Eredion of the Penis there is fo 
much of their Liquor difcharged into the Urethra as 
fuffices to drive out any remains of Urine, and prevent 
its mixing with the Semen; and at other times the conti- 
nual difcharge of fome part of their Liquor into the 
Urethra, defends that paflage from the Salts in the 
Urine : the hke continual exfudation cannot happen ei- 
ther from the excretory Duds of the Proftates or thofe 
of the VefuuU Seminales, becaufe the nearnefs of the 
Sphinder Mufcle fo corrugates the inner Membrane of 
the Urethra, as prevents an eafie paflage of the Liquor 
by the OftkU of the former : nor can the Semen run out 
of the latter, fince the Caruncula or Capit^Gallinaginis is 
ctmtriv'd on purpoie to prevent it i wherefore the 
fhragme. Abdominal Mufcles, and Levatores Ani are 
employed in compreffing thofe parts to difcharge their 
Contents. 
' It is not improbable that the Matter which fliows at 
the latter end of the Cure of Venereal Difeafes, and 
is called a Gleet, proceeds from thefe Glands, and not 
from the Projlata or FeficuU Seminales, as is common- 
ly fuppofed ; which may afford us no mean Argument 
for the Ufe of Injedions in fuch Cafes ; inflead of 
which fbme Praditioners perfecute their Patients with 
violent Purges, and cram them with vafl quantities of 
Aftringent Medicines. We may eafily conceive how 
fuch Gleets become fometimes very Obflinate, if not 
Incurable, by fuppofing the Ulcer in that Contad t© 
happen upon the OftioU of thefe Secretory Duds.
