11 th . — All lameness has disappeared; none can be perceived 
even at a trot. The tumours, though no longer tender to the 
touch, still continue somewhat warm and tense. 
Ylth . — The tumours diminished much in tension, though their 
temperature is still somewhat higher than natural Measuring the 
circumference of the hock, we find a diminution of more than two 
inches in thirteen days ; and in seven days more of one in addition. 
At this time the horse was taken away by bis master to be put 
to work ; and, on that account, from the 25th of August to the 
4th of December following, all observation of him was lost. On 
that day he was, by especial desire, brought to the College for the 
examination of the pupils. The near hock had become all but 
reduced to its natural size, save some fibrous knots upon the 
gastrocnemius tendon, of long standing, and some thickening of 
the. cap of the hock, so long in a state of dilatation. Actual mea- 
surement of the two hocks did not exhibit a difference of more 
than 1J inches in lieu of 14, the former differential admea- 
surement. 
From the report of the pupil Cogeon, 4th year. 
Case II. 
An entire horse, common cart breed, was brought by his owner 
to the Alfort College for treatment. The near hock is double the 
size of the off one, and the history given of it, that the tumour 
has existed a long while, and has been several times fired; and 
that, as a last resource the animal is brought here. A large 
thorough-pin is now present, more prominent on the outer than 
on the inner side, the fluid contents of which can be made to 
fluctuate from side to side by pressure and tapping with the 
fingers. The diseased hock measured, including the tumours, 
twenty-two inches in circumference ; the sound hock around the 
same part but fifteen. The motions of the hock are rendered stiff 
by the impediment occasioned by the tumefactions. 
The Prognostic in this case is grave, both on account of the 
low site of the tumour, and the enormous distention which exists 
of the capsule of the hock joint as well, circumstances exciting 
suspicion that there is communication between the two. Injection 
seems counter-indicated. And yet, as the horse is sent to the 
College for some extreme measures to be practised on him, the 
experiment with iodine must be made. 
Treatment. — Accordingly, on the 4th of the month, as in the 
first case, the inner tumour, at its most dependent part, was pene- 
trated with a trocar, when there flowed out more than a pint 
of synovia. This was followed by the injection of a mixture of
