FILARIOSIS OF THE SUSPENSORY LIGAMENT.

extremities of equities, at least in horses and mules (our observ¬ 
ations on donkeys are not sufficiently numerous to justify ap¬ 
proximation) it is on the suspensory ligament of the fetlock that 
it has its preferred lodging, preference which seems explained 
by the structure of that cord. 
Like others, we have found it sometimes in the connective 
tissue, 8 or io times out of 60. It is then generally in the im¬ 
mediate neighborhood of the suspensory ligament. Once, how¬ 
ever, we found a double parasitic nucleus, resting on the per¬ 
forate tendons, but without being involved with it. 
In the cases where the worm has been found in the middle 
of the connective tissue, without communication with the sus¬ 
pensory ligament, it was always curled on itself or through the 
meshes of the connective tissue, forming a nodule resembling a 
large dried bean in color and in size. To avoid repetition, we 
shall speak of these as parasitic nodules. They are formed by 
the body of the worm, rolled, curled in an inextricable manner 
with the connective fibres by an adenoid tissue and adipose cells. 
A more or less thick coat of fibres surrounds the whole. 
THE PARASITE. 
How to Obtain It .—All means that have been used to obtain 
a complete worm have failed. Dissection under the magnify¬ 
ing glass or the microscope, of pieces of invaded ligament, 
maceration in various liquids and principally of solution of baryte 
of soda, have given us only pieces, more or less long, but im¬ 
possible to assemble. 
The simplest method has given us the best results. It con¬ 
sists in dividing the suspensory in pieces two or three centi¬ 
metres long, and squeezing them between fine cloth. Pieces 
of worms, divided by the knife, are seen bulging out. With a 
fine forceps they are taken hold of and pulled out carefully 
until they break. In this way pieces of various lengths can be 
obtained, varying between one and several centimetres. By 
ment and promote statosis Once dead they undergo calcification with the connective 
tissue surrounding, in such a way as to form irregular masses, sometimes sufficiently 
numerous to invade the entire cord of the ligament.
