it should next pass under and over (or over and under, it is immaterial
which) first the arm and then the thigh, or the thigh and the arm, as the
case may be; (3) in every case, whether rounding the thigh and the arm from
above or below, the piece of rope completing the round should always finish
below that portion preceding it, so that traction upon it from behind the
animal's back should tend to keep all portions of it from slipping below
the knee and the hock.

With the uppermost fore-limb secured to the hind-limb in the manner we have
described, we have the underneath fore-limb suitably exposed for both the
higher and lower operations of neurectomy. The position for this operation
will be made better still if the lowermost limb (the one to be operated on)
is removed from the hobbles and drawn forward by an assistant by means of a
piece of rope fastened to the pastern.

Taking what we have described as a general guide, other modifications of
thus securing the foot will suggest themselves to the operator to meet the
special requirements of the case with which he is dealing.

Regarding the administration of chloroform, no description of the method
is needed here, as it will be found fully detailed in most good works on
general surgery. Where great immobility is needed, it is one of the most
valuable means of restraint we have. Apart from that, its use in any
serious operation is always to be advocated, if only on the score of humane
consideration for the dumb animal helpless under our hands.


B. INSTRUMENTS REQUIRED.

In addition to those required for operations on the softer structures--such
