Symptoms .—While I am of the opinion that more than one 
disease has been described so far in my paper, I think one set of 
symptoms with variations describes both. Sometimes the ani¬ 
mal is noticed becoming emaciated before ceasing to eat; others 
refuse food at once, but in both cases they like to suck at water 
or liquids, apparently afraid or unable to swallow. They shiver 
and bury themselves in the litter, and will not move unless 
urged very much. There is lack of control of the hind parts, 
an unsteady gait, a peculiar sneezing cough is noticed, redness 
of the skin about ears, belly, inside of legs. Diarrhoea sets in 
early and continues until death, but often I have met with con¬ 
stipation replacing diarrhoea. The faeces are of a very black 
color, with a bad odor and ejected apparently with pain. To¬ 
ward death these red spots become darker. The animal becomes 
unable to get up and remains so until death. There seems to 
be soreness of the body, especially over the abdomen. 
Post- 7 nortem .—I made post-mortems on nearly 50 per cent, 
of the deaths. In fully 90 per cent, of the cases the skin about 
the ears, abdomen, thighs, inside of legs were marked with 
blackish spots ; in very few cases there were no external discol¬ 
orations. Some cadavers w-ere very much emaciated, while 
others were plump and fat. The intestines in many cases con¬ 
tained a sticky black faeces of bad odor. At other times it con¬ 
tained a dry black excrement, which cracked like a piece of 
clay when an effort was made to bend it, and as if the stomach 
and digestive apparatus were unfit to do their work. I have 
found where a grain of oats, barley, or wheat was swallowed, un¬ 
injured by the teeth, it took root in the contents of the intestine, 
grew to be three inches long, dying for want of air and moisture. 
In all cases there was inflammation of intestines of a more 
or less marked character. Gangrene had often set in before 
death ; at other times I have found an ulcerated patch of intes¬ 
tine containing this jelly-like stool. The mesenteric glands are 
enlarged and haemorrhagic. The stomach contains a mass of 
undigested material ; the liver is solid, spleen often enlarged, 
kidneys about normal. The lungs are always more or less
