rendered possible an impossible action of the tendon, and again 
on account of the position of the wound, near a centre of 
motion ; of the complications likely to occur, etc. The treat¬ 
ment, however, was simple and the results most satisfactory. 
Use of the slings at intervals as the mare, of a nervous nature, 
would permit. Cold irrigations, antiseptic dressings, iodoform 
applications, lotions of bichloride of mercury solution. The in¬ 
jured tendons in course of time sloughed and the division was 
complete. A piece of necrosed bone from the principal meta¬ 
tarsal exfoliated after some time, and in forty-seven days the 
cicatrix was complete. The animal was free from lameness, 
whether in walking or trotting, but there w^as a little irregularity 
of action, characterized by more flexion at the hock than nor¬ 
mally. This was due to the fact that the upper end of the 
divided tendons was attached to the thick cicatricial tissue 
which remained there, and thus was adding as an annex to the 
flexor metatarsi. The lower end of the divided tendons was 
also adherent to the firm and hard cicatrix, and this fibrous 
band in front of the fetlock and phalanges rcvsisted the possible 
excessive actions of the flexor muscles. All of which formed 
an advantageous condition, which explained the regularity of 
action of the animal .—{Revue Veteri?i.) 
Contribution to the Study of Capped Hock \_By 
M. G. Pichoii \.—A three-year-old mare had a large hygroma 
of the left hock. The accnmulation of the serosity was so large 
that it lamed the animal, whose hock was quite painful. 
Thrown on account of the very nervous condition of the ani¬ 
mal, it was found on manipulating the tumor that on its inside 
a small hard, elongated body could be felt, floating in the 
serosity, fixed by one of its extremities on the snpero-external 
wall of the hygroma, but free by the other. The hairs were 
cut over the tumor, the skin sterilized with cresyled water, the 
cyst was freely opened on its posterior wall, the sac emptied, 
the little hard body extirpated. The cavity of the cyst w^as 
cleaned with weak solution of tincture of iodine, and the edges 
of the wound sewed up with sutures, injections of cresyled water 
being made through a drainage tube placed at the lower end of 
the incision. The wound healed rapidly and left but little 
cicatrix. The foreign body was formed of a very hard fibrous 
substance, covered here and there with large vesicles, filled with 
serosity. It measured 4 centimeters in length.— {Rec. de Med.
