be stopped. After a month electricity was taken up again, 
alternately with cold douches, massage, and walking exercise. 
Four months and a few days after, the lameness was scarcely 
perceptible in walking, but was yet marked in trotting. It is, 
however, hoped that it will soon disappear altogether, as the 
atrophy is gradually passing off. Indeed, after 137 days of lay¬ 
ing up altogether, the animal resumed his work as good as 
ever. 
Observation II .—A nine-year-old horse, used for double 
purposes, had a deep punctured wound of the left fore foot. He 
was very lame and was carried in an ambulance to the hospital 
at Hyon. One month ago, he became suddenly and severely 
lame on the left fore leg. The foot was examined, and a nail, 
implanted in the frog, was extracted. The animal was treated, 
improved, and was returned to his work. He soon became so 
lame that he had to be transported in an ambulance. In fact, 
the left fore leg did not assist in the carrying of the body, either 
in walking or at rest; it was the seat of lancinating pains. The 
diseased foot was unshod with a great deal of care ; it was well 
pared down thin, and the following lesions were exposed : In the 
middle zone of the plantar face of the hoof and towards the 
anterior part of the lateral lacuna, there was a fistulous wound, 
with swollen edges, filled with yellowish, viscous pus, mixed 
with clots of synovia. Around the frog, the hoof was all loose 
as far as the internal glome of that organ. The foot was hot, 
the pulsations of the internal collateral artery of the cannon 
were strong and more readily felt on the left than on the right 
side. The history told the nature of the case; the severity of 
the lameness, lancinations, fistula on the middle zone of the 
plantar region, and specially the flow of synovial pus showed 
that it was a deep penetrating punctured wound, involving the 
whole thickness of the plantar aponeurosis to the small sesa¬ 
moid synovial bursa. The absence of swelling at the. coronet, 
and of the leg, induced the belief that the interosseous ligament, 
joining the navicular to the os pedis, was intact and that the 
inferior cul-de-sac of the synovial sac of the joint was not open. 
Notwithstanding the fact that the trouble was one month old, it 
was feared that the necrotic lesion, characterized by the plantar 
fistula, may have involved little by little the whole plantar 
aponeurosis, the interosseous ligament and the articulation. 
The classical operation was indicated to prevent all those acci¬ 
dents. However, as in some similar or at least much like cases, 
we have obtained full success with trochiscus of sublimate corro-
