forces, the peristaltic and the anti-peristaltic, opposing each 
other, and, in a manner, struggling to occupy that portion of 
the intestine in a kind of cylindrical and flexible column, and at 
certain places the mucous membrane was of a red colour — in others 
it was brown or black. Its thickness increased from the circum- 
ference to the centre. There was a considerable gelatinous, or 
rather sanguineous deposition ; no portion of any of the intestines 
presented the least trace of rupture. This observation is interest- 
ing, for it was the first case in which volvulus of the intestine had 
been considered as a cause of vomiting in the solipede. 
External Pathology and Surgery. 
Six hundred and sixty-seven complex surgical operations were 
practised. 
The treatment of these lamenesses, which consists in the appli- 
cation of a fragment of corrosive sublimate under the skin near to 
the joint that was lame, has continued during the year with almost 
uniform success. We have lately treated anew 118 horses, asses, 
and mules, for lameness in the shoulder, and 30 times for lame- 
ness having its seat in the articulation of the femur with its basin. 
This powerful revulsive does not always remove the lameness, 
but, at least, as often as the transcurrent cauterization, and does 
not leave any trace of it, the cicatrix disappearing under the 
skin. 
In any time of the year during the rigorous cold, as well as the 
scorching heat, there are observed tumours almost constantly mor- 
tal, which occasionally follow the use of setons. The voluminous 
engorgement produced by the bichloride of mercury dissipates 
them all. At two separate times farcy attacked a wound in the 
shoulder ; but a cure was easily obtained. 
Castration has been performed during the last year on 24 
horses, 8 asses, and 5 mules. Among the different modes of pro- 
ceeding we gave the preference to the operation with the clams 
and the “ testicle-couvert.” All that were operated upon were cured, 
without exception and without accident. The engorgement that 
has followed the operation has sometimes been almost nothing, 
and in every case less developed than in the castrations with “ les 
testicules couvert.” No bleeding followed the operation. Lotions 
of every kind applied to the sexual parts were rejected. The white 
water and gentle exercise were oftenest recommended. 
Tenotomie . — Division of the pectorans tendon has been per- 
formed on ten horses, all of which were cured and rendered good 
service, notwithstanding the operation had been performed accord-
