later there is generally a liquid and fetid (bad smelling) diar- 

 rhoea, and persisting to the end. At first the eyes are congested 

 and watery, but soon the secretion thickens, becomes yellowish, 

 collects in the angles and sticks the lids together. The breath- 

 ing is quicker than usual, acompanied by a cough, which, how- 

 ever, is not very frequent, and generally heard when the animals 

 are driven from their bed. The skin may be congested and red 

 on different parts of the body, varying from a pinkish red to a 

 dark red or purple. Sometimes there is an eruption, which 

 leaves crusts or scabs of various sizes over the skin. There is a 

 rapid loss of flesh, the animal grows weak, stands with arched 

 back and the belly drawn up, and walks with a tottering, uncer-

 and the weakness and exhaustion increase until death takes

 affecting the hogs, on neighboring farms, we may be safe in say-

 othr such disease has been recognized in this country. 



In anthrax districts there may be occasional outbreaks of the 

 disease, in which there is great inflammation and swelling of 

 the tongue, or of the throat, or simply a fever with no visible 

 swellings. If the disease is anthrax, other animals, such as horses, 

 cattle and sheep, will also be affected. 



The carcasses should be examined after death, and if project- 

 ing, button-like ulcers are found in the large bowels, we know 

 that hog cholera is present. It must be remembered, however, 

 that these ulcers are not found in the most acute cases, but only 

 in the sub-acute and chronic, where life is prolonged a sufficient 

 time for them to form. If there is inflammation of the lungs, and
