126 DISEASES OF SWINE AND OTHER ANIMALS. 



in Eowan, Mecklenburg, Lincoln, Gaston, and Alamance, in tlie central 

 belt, and particular inquiries were made of those who had observed it 

 in the counties bordering on the coast. Several counties not euumera- 

 ted above were visitxsd, but I was not successful in findiug infected 

 localities. My greatest legret is that I was not able to make personal 

 observations in every part of the State. 



In each of the counties mentioned a considerable number of herds 

 were visited and examdned, and mthout exception the Uviug animals 

 presented similar symptoms, and the dead ones sliowed similar c}ianges 

 in the different organs of the body. Slight variations were of course 

 observed, as is always the case in any disease, but these were as great 

 between (liferent indi-vdduals of the same herd, sick at the bame time, 

 as between different herds, even in different counties. And, what is of 

 great importance, 1 did not find a single case in which it could x^ossibly 

 be supposed that death resulted from a local disease; but in every 

 case a variety of oigans, belonging to different apparatus, were found 

 diseased ; the blood often showed marked changes ; there were extrava- 

 sations in various parts of the body, and always inflammation of the 

 lungs and large intestmes, generally, also, of the heart, and often of the 

 eyes; the skin, too, was often plainly affected, and the temperature was 

 found to be increased before any other symptoms of disease were in the 

 least apparent. 



Considering all these facts, there can be no doubt that these animals 

 all died of a general disease — a disease not caused by changes in any 

 single organ ; but, on the contrary, a disease which caused the various 

 organic changes observed. Again, from the similarity of symptoms in 

 all these cases which I saw, and in those reported to me from other 

 parts of the State, and from the correspondence in post-mortem apjiear- 

 ances, there can scarceh i emain a shadow of doubt that the great mass 

 of the hogs dymg in North Carolina are affected by one and the same 

 disease. 



SYIMPTOMS. 



An increase of temperature precedes for an undetermined and f>rob- 

 ably variable length of time the appearance of all other symptoms. 

 In one lot of seven ten-months-old pigs, only one of which showed symp- 

 toms of disease, the sis; remaining had a temperatiu-e varying from 

 lO^.G"^ F. to 106° r., and this temperature was preserved unaltered for 

 six days, with no other changes in the condition of the animals than 

 increased dullness of the eyes, a general imthrLfty condition and a disin- 

 clination to search for food, although the appetite was still good. The 

 pig first affected died about this time, and a post-mortem examination 

 left no doubt of the disease. 



In another lot of ten three-months-old pigs, but one of which was 

 plainly sick, six had a temperature ranging from lOip F. to 107° F. ; 

 with one this was 103^^ F., with two 101o"F. and 102° respectively, while 

 with the sick one it reached 107.4° F. 



In a herd of twelve, from which one had just died, and one was plainly 

 sick, four others showed a temjieratm-e from 103^° F. to 107° F. 



In a lot of fourteen animals, one had died, one was plainly sick, and 

 three others had a temperature from 103° F. to 104° F. 



Of five pigs, one had just died, three had a temperature or 105° F. to 

 100° F., and the remaining one 103° F. 



Of eleven hogs, two had died, one was plainly sick, and five had a 

 temi)eratiu^e ranging from 103° F. to 100° F. 



From these and similar cases it has seemed probable that a high tern-
