This disease is sometimes called water dread and canine rabies, 

 from the fact that it is only generated in the dog and feline species 

 of animals. 



Cause in Horses. Bites of the mad dog, and sometimes the bite 

 from the common cat is capable of producing the disease. 



Symptoms. In those cases that came under my notice the 

 symptoms were anything but like each other. In one animal, the 

 propensity to bite at objects was more severe ; and in another, the 

 horse would walk and look about him, utter a peculiar sound, and 

 lie down and get hold of the heels and part of the arm of the fore 

 leg with his teeth, till he had them bleeding, get up again, and 

 walk about without any apparent object in view. But the de- 

 structive impulse attributed by some authors, I think, is merely 

 the fancy of an inexperienced mind in such matters. The symp- 

 toms of the mule differed from each of the horses, inasmuch as he 

 would, at times, eat hay very ravenously, stop all at once, and 

 with a peculiar sound, not like the bark of a dog, but of a char- 

 acter which cannot be described, lie down and have a good roll to 

 himself; then he would run at any person within his reach with 

 open mouth. But in no instance did any of the cases attempt to 

 bite at anything not endowed with animal life. All of these 

 animals were confined in enclosures from which they could not 

 escape. They lived about thirty-six hours after the actual symptoms 

 of the disease set in. (See Bites of Mad Dog.) Any person hav- 

 ing the least experience with horses, may observe peculiarities, at 

 times, which do appear not to belong to common diseases. 



Hypertrophy. — This name means a state of certain organs in- 

 creased in size, and decreased in power. The heart, kidneys, 

 spleen, liver, and other parts of the body, are liable to this dis- 

 ease. 



Hypodermic. — Under the skin. (See Endermic.) 



Hysteria. — This is a disease which is sometimes seen in mare§ 

 only. 



Causes. Irritation of the uterus, or of some of its nerves. 



Symptoms. Great excitement and incapability of standing, and 

 it appears as if some of the bones of the back or loins were 

 broken. 



Treatment. Give twenty drops of the tincture of aconite root
