DISEASES OF SWINE AND OTHER ANIMALS. - 328 
* before any other symptom of the disease was in the least apparent. In 
every herd where the disease had prevailed to any considerable extent, 
no case was found where death had occurred from. a local malady, but 
all the lesions and appearances unmistakably indicated the existence of 
the’ general disorder. In but few cases was death found to have resulted 
from the affection of any single organ, but on the contrary seemed to 
have been the result of the various organic changes observed. 
Dr. Detmers says that the morbid process, although in all cases essen- 
tially the same, is not restricted to a single part or organ, or to a set of 
organs, but can have its seat almost anywhere—in the tissue of the 
lungs; in the pleura and pericardium; in the heart; in the lymphatie 
system; in the peritoneum; in all mucous membranes, especially in 
these of the intestinés; in the liver; in the spleen, and even in the skin. 
Only the pulmonal tissue and lymphatic glands are invariably affected. 
*The most constant and unvarying symptom of the disease is observed 
in the inereased temperature of the body. Indeed, one of the examiners 
regards it as highly probable that a high temperature may exist several 
weeks before other symptoms are manifested, and that the disease may 
-in some eases even be confined to and run its course in the blood with- 
out a localization in any other organ or organs. A few isolated cases 
are noted where this symptom was lacking, but it may have been pres- 
entin a mild form before other symptoms were observed. The external 
symptoms of the disease, which were found to be almost identical in 
all the widely-separated localities in which examinations were made, 
were a dullness of the eyes, the lids of which are kept nearer closed than 
in health, with an accumulation of secretion in the corners. There is 
harfging of the head, with lepped ears, and an inclination to hide in the 
litter and to lie on the belly and keep quiet. As the disease advances, 
_the animal manifests more or less thirst, some cough, and a pink blush 
- or rose-colored spots, and papular eruption appears on the skin, particu- 
larly along the belly, inside of the thighs and fore legs, and about the 
ears. There is accelerated respiration and circulation, increased action 
of the flanks in breathing, tucked-up abdomen, arched back, swelling of 
the vulva in the female as in heat; occasionally, also, of the sheath of 
the male, loss of appetite, and tenderness of the abdomen, sometimes 
persistent diarrhea, but generally obstinate constipation. In some 
cases large abraded spots are observed at the projecting points of the 
body, caused by separation and loss of the epidermis. In such cases 
a slight blow or friction on the, skin is sufficient to produce such 
abrasions. In many cases the eruption, blush, and spots are entirely 
absent ; petechiz are formed in only about one-third of the cases. In 
.some cases there is considerable inflammation of and discharge from 
the eyes. Some animals emit a very offensive odor even before death. 
In large herds, where the disease prevails extensively, this offensive 
effluvia can be detected for a great distance to windward. In nearly all 
cases there is a weakness or partial paralysis of the posterior extremi- 
ties, and occasionally this paralysis is so complete in the first stages of 
the disease as to prevent walking or standing. 
As symptoms of special diagnostic value, which are scarcely ever ab- 
sent in any case, the following are mentioned: Drooping of the ears and 
of the head; more or less coughing; dull look of the eyes; staring ap- 
pearance of the coat ef hair; partial or total want of appetite for food; 
vitiated appetite for execrements; rapid emaciation; great debility; 
weak and undecided, and frequently staggering, gait; great indifference 
to surroundings; tendency to lie down in a dark corner, and to hide the 
nose and even the whole head in the bedding; the specific offensive
