as they pafs over the proftate gland and neck of the 
bladder, and inofculating or communicating very fre- 
quently, they form a kind of network or embroidery. 
From hence they are continued through the cellular 
membrane behind the internal coat of the bladder, 
and feem to join w^ith the lymphatics of the 'uejiculce 
feminales, to be continued with them to the neigh- 
boLiring glands, and fo on to the thoracic dudt. 
I have not been able to find lymphatics in any other 
part of the urethra ; indeed, this canal feems to be 
perfedlly void of them till we come to its membranous 
portion, where we meet with thefe I have been de- 
fcribing ; and it may be remarked, that here they are 
placed in that part of the urethra where the greatefl 
quantity of moiflure is fupplied. Very probably the 
fealing up the mouths of thefe delicate veilels, by fre- 
quent inflammation and induration, may give rife to 
that obflinate Jiillicidium which is feldom or ever - 
cured ; owing to an accumulation of thin fluids, with 
a faulty abforption. 
Thefe lymphatics of the urethra and bladder alfo 
point out the road, by which any fubtle virus may pafs, 
with the lymph, diredtly into the mafs of blood, and 
contaminate the whole habit, without giving the leafl 
appearance of any local diforder. 
To have a clearer idea of the vefTels I have been 
treating of, I muff beg leave to refer to the drawing 
annexed, in which thefe lymphatics of the urinary 
bladder and urethra^ in the human body, are care- 
fully and very accurately delineated.
