_Symptoms._--The ox suddenly becomes very restless, stamps with his feet, moves backward and forward, hurriedly lies down, rises, moves his tail uneasily, and kicks at his belly with the foot of the affected side. The pain evinced may diminish but soon returns again. In the early stage there are frequent passages of dung, but after the lapse of 18 or 24 hours this ceases, the bowel apparently being emptied to the point of strangulation, and the passages now consist only of a little mucus mixed with blood. When injections are given at this time the water passes out of the bowel without even being colored. The animal lies down on the side where the hernia exists and stretches out his hind feet in a backward direction. These two particular symptoms serve to distinguish this affection from enteritis and invagination of the bowel. As time passes the animal becomes quieter, but this cessation of pain may indicate that gangrene of the bowel has set in, and may, therefore, under certain circumstances, be considered a precursor of death. Gangrene may take place in from four to six days, when perforation of the bowel may occur and death result in a short time. _Treatment._--In the first place the ox should be examined by passing the oiled hand and arm into the rectum; the hand should be passed along the margin of the pelvis, beginning at the sacrum and continuing downward toward the inguinal ring, when a soft, painful swelling will be felt, which may vary from the size of an apple to that of the two fists. This swelling will be felt to be tightly compressed by the spermatic cord. It very rarely happens that there is any similar swelling on the left side, though in such cases it is best to make a thorough examination. The bowel has sometimes been released from its position by driving the ox down a hill; by causing him to jump from a height of 2 feet to the ground; the expedient of trotting him also has been resorted to with the hope that the jolting movement might bring about a release of the bowel. If the simple expedients mentioned have been tried and failed, then the hand being passed into the rectum should be pressed gently on the swelling in an upward and forward direction, so as to endeavor to push the imprisoned portion of the bowel back into the abdomen. While this is being done the ox's hind feet should stand on higher ground than the front, so as to favor the slipping out of the bowel by its own weight, and at the same time an assistant should squeeze the animal's loins, so as to cause it to bend downward and so relax the band formed by the spermatic cord. If the imprisoned portion of gut is freed, which may be ascertained by the disappearance of the swelling, the usual sounds produced by the bowels moving in the abdomen will be heard, and in a few hours the feces and urine will be passed as usual. If the means mentioned fail to release the imprisoned portion of the gut, then an incision about 4 inches long must be made in the right flank in a
