=Ruptured diaphragm= is attended with a soft cough, and symptoms of broken wind--occasioned by the almost sole employment of the abdominal muscles--with sitting on the haunches. Still, Professor Spooner, of the Royal Veterinary College, mentioned in his lectures that an animal belonging to the Zoological Society lived two years with a ruptured diaphragm, through which the bowel protruded into the thorax. In the horse such a lesion is speedily fatal. [Illustration: A POSITION OFTEN ASSUMED BY THE HORSE SUFFERING FROM ABDOMINAL INJURY.] A position so unnatural as that of sitting on the haunches may denote something very wrong to be present; but it gives no definite direction to our ideas. Animals are known to have assumed it, and subsequently to have recovered. The diaphragm when it yields generally gives way upon the tendinous portion. Through the opening the peristaltic action soon causes the bowels to obtrude; and death is produced by displacement and strangulation of the intestine. The posture previously delineated is common to all injuries of the abdomen; so is the opposite peculiarity--or the horse remaining upon its chest. The last attitude may not, to most persons, appear so strange, seeing that the creature assumes it whenever it rises or lies down. Then, however, it is only momentary. When it denotes abdominal injury, it is comparatively of long continuance. At the same time the breathing and the countenance bespeak the greatest internal anguish. [Illustration: TEST FOR HEMORRHAGE FROM THE SPLEEN.] =Ruptured spleen= is the gentlest death of all those which spring from abdominal injury. The spleen is at present a mystery to veterinary science. It has been discovered after death of enormous size; but the symptoms during life had not led to the expectation of any very serious disorder. Ruptured spleen and ruptured liver are both productive of similar symptoms; both answer to the same tests, and the termination of each is alike. [Illustration: A RUPTURED STOMACH.]
