well defcrlbed by authors, as exceeding fine, tender, 
and tranfparent veffds, frequently joining into one 
another, and interfeded by a number of very delicate 
membranous pouches or valves; fo that, having an 
injedlion thrown into them, they give the appearance 
of being full of little knots. 
The lymphatics are apparent enough, when they 
unite and grow large; but from their exility, want of 
colour, and tranfparency, are very difficult to be dif- 
covered before. 
Owing to thefecircumftances it is, that their origins 
have never before been feen ; and that in many parts 
of the body, where they are neverthelefs fuppofed to 
cxifl, they flill lie unnoticed. Haller, after fpeaking 
of thefe veffels in many other parts of the body, goes 
on thus: Quee a pene veniunt mihi minus nota

flrudlure of the human body, knows nothing of thefe 
lymphatics of the bladder, or membranous portion of 
the urethra. 
The lymphatics of the urinary human bladder and 
urethra^ firft Ihevv themfelves on each lide the veru-

In their natural flatc, they appear like fo many fine 
threads lying dole together, but diverging afterwards,
