Some operators prefer to use a trocar, slightly exceeding in diameter the ring to be worn ; in that case the manual technique is the same. The puncture is made, the trocar alone is withdrawn, and the canula remains iii. situ; one extremity of the ring is then inserted into the canula, and both.

There is no difficulty in thus inserting the ring, though puncture with the trocar is perhaps rather less convenient than with the bistoury. Eelative control without casting may also be efTected by attaching the end of the tail to the base of the horns or the head to the cannon bone of a front or hind limb. These methods, however, are of little value except to prevent animals at grass from escaping entirely during operation. CONTROL BY CASTING.
