If the cannula is used, allow the hair or wire protruding from the end to form a small loop just large enough to slip over the testicle. Work this over the testicle, being careful to inclose the entire organ. Now tighten up on the free ends of the hair or wire being careful not to catch any part of the artery. If the spermatic cord does not separate, saw lightly with Fig. 6

If only the upper testicle has been removed, turn the bird over and proceed in exactly the same manner upon the other side. After removing the testicle, if the bleeding is at all profuse it is well to remove a portion of the blood by introducing small pieces of absorbent cotton into the body by means of the hook or nippers, allowing them to become saturated and then removing them. Be sure to remove all blood clots, feathers, or foreign matter. After the testicles and all foreign matter are removed, take out the spreaders, thus allowing the skin to slip back over the incision. LOSSES DUE TO CAPONIZING Even experts are sure to kill some birds, but the loss is small, seldom exceeding 5 per cent where any considerable number are caponized, and usually not more than 2 or 3 per cent. With be- ginners, of course, the percentage is much larger, but with a little *«
