lary vessels. The appearances were precisely alike m both legs. 
Quadrupeds affected with thoracic disease, not being able, like 
the human being, to rest on the back, but forced long to maintain 
a standing position, in order to avoid that painful pressuie on 
the chest°(or rather that loss of power over the auxiliary respira¬ 
tory muscles of the chest.— Ed.) which results from lying down, 
suffer much pain from weariness of the limbs, and these limbs 
are often seriously injured. Thus, at the close of these diseases, 
we have inflammation of the foot, contraction of the tendons, 
swellings about the knee or hock, 8cc. These have been ob¬ 
served by many veterinarians, and I do not speak of them as 
discoveries of mine j but 1 believe that rupture of the peifoians 
tendon, connected with these diseases, is a new fact.

Rupture of the Tendon of the Perforatus. 
j By the same. 
At the end of June 1831, I examined a mare labouring under 
the last stage of pulmonary phthisis. She was treated for this 
disease, but without beneficial effect. 
On the 28th of July she was led out to the parade with the regi¬ 
ment, although the soldier was forbidden to do it; he mounted her, 
and she was trotted with the rest; when all at once she became 
covered with sweat, she breathed laboriously, and she could 
scarcely move. The soldier dismounted—she was led with much 
difficulty to the stable, and l saw her. She was covered with 
sweat, her breathing was quick, her nostrils dilated, her eyes 
sunk, her pulse full and frequent, her croup and hind quarters 
depressed, her hocks straighter than in their natural position, 
the flexor tendons of the hind limbs stretched, and painful, with 
evident enlargement above the fetlocks, and the skin of the an¬ 
terior face of the fetlocks forming several transverse folds. It 
was evidently painful to her to stand—every motion indicated 
excessive pain; she lay down as much as she could, and raised 
herself with great difficulty. We gave her up as lost ; we were 
assured that a tendon was ruptured, but we could not determine 
whether it was the perforatus or the perforans. 
We bled her, fomented her legs, administered injections, and 
put her on spare diet. She remained until the 2d of August, 
generally stretched upon her litter, eating and drinking every 
thing that was given to her. It was with great pain that she rose, 
and she lay down again immediately. She got thinner every 
day ; and a mortal disease having existed previously to this injury 
of the tendons, we destroyed her.
