COM PTE KENDU OF THE 
parts, it is observed that the cellular body adjacent to the dartos 
is the seat of a slight yellowish serous infiltration. The serous 
vaginal membrane is injected, reddish, and has contracted 
adherences in several parts of its extent. The epididymis is 
considerably tumefied. The cellular substance which contains 
the circumvolutions of the canals is reddish, and covered with a 
pseudo-membranous pellicle. In cutting the substance of the 
organ, a considerable quantity of a very thick purulent liquid 
escapes on pressure of the orifices of the canals. These canals, 
very much dilated, constitute isolated collections. At the point 
of the prepuce the testicular cord is infiltered, and sometimes 
purulent. 
The substance of the testicle is somewhat discoloured, and 
seems to have experienced a commencement of atrophy. 
In cases where the scrotal tumour outwardly presents the 
first characters that we have assigned to it, if we dissect it we 
observe, 1st, A serous state of infiltration of the cellular sub- 
dartesian tissue, with injection of this tissue. 2d, The cha- 
racter of an acute inflammation of the vaginal sheath, with 
formation of false membranes, and the presence of purulent 
collections multiplied in the vessels that are constituted by 
these false membranes. 3d, The purulent state of the epidi- 
dymis, which we have already described ; and, 4th, and finally, 
A considerable and prolonged engorgement at the top of the 
testicular cord, with purulent collections in the cellular tissue 
entering into its composition. The testicular substance is some- 
times sound ; but at other times it encloses little yellowish dis- 
seminated points. Usually it is discoloured. 
Finally, in its third form, the sarcomatous engorgement is essen- 
tially constituted by an alteration of the testicle itself. The sub- 
stance of the organ has submitted in its totality, or in several of 
its parts, to a transformation which renders it like liver boiled and 
softened. When the cortical envelope is cut, a very thick pus 
escapes, which has a sickly and faint smell. This alteration is 
usually connected with a purulent state of infiltration of the va- 
ginal sheath ; also with purulent secretion in the canals of the 
epididymis, and considerable engorgement of the testicular cord, 
which is often as large as a man’s arm. 
The disease, of which we have just described the symptoms 
and studied the alterations, recognises, like glanders, as its pre- 
disposing cause, the excess of labour to which the animals have 
been compelled to submit It is, in fact, almost exclusively the 
lot of post or diligence horses, or those that are employed in 
heavy carts of stones or in cabriolets, and which, to the present 
day, continue to be so badly constructed. 
Why is this place chosen for purulent collections in the epidi-
