“ Dr. James Law, of Itliaca, N. Y., (in his report to the Com¬ 
missioner of Agriculture) records the lungs of some of his experi¬ 
mental pigs as ‘healthy,’ ‘sound,’ ‘normal,’ etc., which simply 
shows that the pigs were not affected with swine plague, and did 
not die of that disease. 
“ It may also be mentioned in all cases of swine plague most of 
the lymphatic glands are more or less enlarged, and that com¬ 
paratively more schizophytes can be found in them than in any 
other part of the animal body .”—American Naturalist , vol. 16, 
p. 301. 
3. Swine plague proper is a strictly infectious disease, and not 
a contagious disease in any sense of the term. 
4. That the so-called “characteristic” ulcerative and neoplas¬ 
tic conditions, so frequently found in the large intestines in swine 
plague, are not necessary complications in that disease; and, 
hence, are not pathognomonic to it. 
(That is, they do not form the pathological ends of American 
swine plague.) 
5. That death can be induced in healthy swine by inoculating 
them with an extra quantity of very virulent virus, without there 
being an essential lesion present other than those in the lymph 
glands, and more or less ecchymotic hemorrhage. 
(In such cases the animals die of an infectious septicaemia 
only.) 
6. That those cases of swine plague which are characterized 
by an intense cholerine discharge are more frequently free from 
the so-called “characteristic” ulcerative lesions in the large intes¬ 
tines than complicated by them. 
7. That the cases characterized by the so-called “ characteristic ” 
intestinal lesions are more often accompanied by constipation un¬ 
til the last stages, than by diarrhoea. 
8. The choleroid discharges are, in reality, those generally 
accompanying the last stages of septicaemia; and, hence, are not 
dependent upon ulcerative lesions in the intestines. 
9. That the term “ hog cholera ” is a misleading misnomer, 
and that the disease is really a septicaemia, with the lesions in the 
lymph glands and lungs as its peculiar characteristic, but also
