are affected, at others one more than the other, and then again 
they are both clear and the body of the ligament is swollen. 
These lesions belong surely to the parasitism ; they always 
are connected with the presence of the filaria, accompanied with 
the new formations it gives rise to. 
In the case of recent invasion, the transverse section of the 
ligament shows nothing abnormal, or, at the very most, one 
may see in the interfasicular connective tissue one or two holes, 
resembling arterioles without coats. In pressing on the sec¬ 
tion, one will see oozing through these holes a whitish trans- 
lucid thread, visible to the naked eye ; it is the body of a 
nematode. 
If the lesions are older and more numerous, the section is 
of dirty yellow or greyish color, with marbled lines of cicatricial 
tissue. The canalicular pores are numerous, and sometimes 
quite large, as having mingled several together. By pressure 
the worms are squeezed out, isolated in fragment or in bun¬ 
dles. 
The connective tissue surrounding has changed its white 
nacreous aspect and become of a dirty yellow tint; it is thickened. 
On a longitudinal section of a dried piece one may, by trans¬ 
lucidity, observe the spires and sinuosities formed by the nema¬ 
tode. Quite frequently the ligaments present on their surface 
irregular nodosities, more or less projecting, forming sometimes 
quite large nodules. These, one or two in number, seldom 
more, are observed once in every five or six cases of diseased 
ligaments. These swellings are formed by the worm, which 
has come out of the fibrous fasciculi of the ligament to come 
and curl itself in the peripheric connective threads.

PATHOLOGICAL CONSEQUENCES OF FILARIOSIS OF THE SUSPEN¬ 
SORY LIGAMENT. 
The pathological importance of filariosis of the suspensory 
ligament of the fetlock of the horse depends evidently on its 
frequency and its severity. 
Frequency of the Affection .—It is very common. In a series
