cult to conceive how the feed can be propel- 
led thro’ a tube fo {mall, fo much convoluted, 
and of fuch a length as the fingle one, which, 
according to De Graaf, forms the epidydimis «. 
on thefe accounts, I think, there is reafon to 
doubt this ftru@ture which he afferts, till we 
have more fatisfying proof of it than has hi- 
Such the following 
appears to be. Jf, in attempting to make 
preparations like to thofe above defcribed, an 
extravafation happens in any part of the epi- 
adydimis, or if any of its convolutions are tied, 
not a drop of the injection can be pufhed 
farther towards the tefticle than this extrava- 
fation or ligature: and, if the epidydimis is 
cut acrofs, while quickfilver is poured into 
the tube fixed in the vas deferens, it {quirts 
out only at one orifice in this cut part; which 
is the plaineft and moft convincing, demcn- 
- ftration of the body of the epidydimis, being 
_intirely compofed of a fingle tube convoluted
