ing to the old method of proceeding, which consisted in making 
a longitudinal incision, that had the inconvenience of permitting 
too easily the introduction of air into the wound and producing 
occasionally sad complications. The subcutaneous operation ap- 
pears to us to be the preferable one, and we shall certainly here- 
after adopt it. 
Plantar Neurotomy . — This was attempted on the right fore leg 
of a mare destined to light draft work. A violent contusion of 
the foot had caused a permanent lameness, which could not be reme- 
died. The pain and the lameness, however, ceased after the sec- 
tion of the posterior branch of the plantar nerve on either side; 
nevertheless, the redness and ecchymosis of the horn remained. 
Since the operation she has taken several long journeys, and the 
limb seems to have regained its pristine soundness. 
Accidents connected with Bleeding. 
A very great number of venesections have been made from the 
jugular vein of the horse and the dog. This could scarcely be 
effected without the occurrence of occasional accidents. We have, 
however, met with only one case of thrombus, which occurred to 
a horse after a bleeding practised in our school. Once only have 
we been called upon to combat an accident, fortunately very rare, 
and the consequences of which may be fatal. Some globules of air 
introduced themselves into the jugular vein while the operator 
deposited on the ground the vessel filled with blood. Some seconds 
afterwards the horse staggered, widened all his limbs, and was 
utterly unable to move. In an instant another bleeding was made 
on the opposite vein. The blood that flowed from it was of a ver- 
milion colour ; but in a moment the respiration of the animal be- 
came laborious, he fell, and seemed to die. Frictions with the 
essence of turpentine on almost every part of him were immedi- 
ately resorted to, five minutes after which he got up, and was re- 
conducted to the hospital. In another five minutes he appeared to 
be well. 
Thirty cases of thrombus occurred among the horses that were 
bled at the school ; in each of them was a fistula more or less 
profound. The cauterization was effected by sharp points being 
applied, and penetrating along its track. In twenty-two of these 
tumours that were caused by extravasation of blood the vesica- 
tory ointment produced resolution, whether the malady existed or 
not under an acute form. 
Bandages . — Professor Mayor, of Lausanne, in a visit which 
he paid to the school during the scientific congress, wished to try
