The parts are magnified 35 diameters, or 1225 superficies. 
The outline of the section of the body of the testicle on 
which the coagulum lies, and to which it is attached, is dis- 
tinctly marked, and the exhalant arteries from the cover-

small, and in no proportion to any part of the tubes 
in the coagulum with which they have opened a commu- 
nication. 
The canals in this coagulum have acquired a regular shape, 
having undergone considerable changes since their first for- 
mation, which gives them a much nearer approach in appear- 
ance to the ramifications of arteries. They have acquired 
regular coats distinct from the parts by which they are sur- 
rounded.
