with the hobbles on the side which is to be operated upon ; the 
upper fore limb is taken from the hobble and by means of a side 
line secured to the corresponding hind one. The lower fore 
limb (the one to be operated upon) is also taken from its hobble 
and the bar hobble applied to it and shin of the hind limb. 
The limb is also held firmly in extension by an assistant with a 
strap or rope. Having thus well secured your animal, and ha\- 
ing sponges, antiseptic solutions, etc., and the necessary instill¬ 
ments ready, which are : two bistouries, one convex and one 
straight, a grooved directory, curved scissors, bull-dog forceps, 
plain dissecting forceps, a couple of blunt retractors, and a blunt 
tenaculum, you are prepared to proceed. 
The operation is performed upon the inner side and upper 
portion of the fore arm. The point for the incision is immedi¬ 
ately under the round eminence formed superiorly by the 
humero-radial articulation, and interiorly by the bicipital tuber¬ 
osity and the rough impressions back of it. Placing the finger 
just inferior to the above eminence, feel for the posterior border 
of the radius, and make your incision just a little posterior to 
that border, say a quarter of an inch. By observing this point 
you will generally be right over the nerve and posterior to the 
vein. At this point make your incision through the skin, about 
one and a half inches long, then cut through and parallel with 
the fibres of the sterno-aponeuroticus muscle ; then go through 
the cellular tissue, when you will come down upon the anti- 
brachial aponeurosis, which is attached to the posterior border 
of the radius, and is dense and inelastic. Now carefully take 
hold of this aponeurosis with your bull-dog forceps, raising it 
slightly, and carefully puncture it sufficiently to allow the in¬ 
troduction of the grooved directory, using this as a guard 
against injuring the vein. By cutting from within outwards, 
divide this aponeurosis to the extent of your outer incision. j 
Have an assistant hold the edges of the wound apart with at 
pair of blunt retractors. We now see the internal flexor of the 
metacarpus. In front of this muscle we should see the nerve, 
which is recognized by its whitish color, flattened form and sen-
