HOG CHOLERA, OR SWINE PLAGUE. 411 
that State. On account of lack of funds, Dr. Billings has been 
rgely limited in his work to outbreaks in the vicinity of Lincoln, 
though he has made several trips of 100 miles or more into dif- 
rent parts of the State. The first case of swine plague that 
I me under his notice occurred in swine belonging to Mr. W-, 
ho lives about nine miles west of Lincoln. lie had but a few 
ses, and these took a slow and chronic course. The doctor 
lied one of the animals, and on making an autopsy found the 
laracteristic lesions of swine plague. The spleen was at once 
moved and placed in a sterilized bottle and taken home, and 
imerous agar. agar, tubes inoculated, in each of which devel- 
)ed one form of micro-organismal life. As soon as possible, a 
unber of hogs were inoculated with these cultures, each of which 
ed in the course of eight to fifteen days with unmistakable 
sions of the disease. Cultivations from the spleen of these 
fimals gave the same micro-organism as was found in the first 
stance. They were also found in the tissue of the intestine and 
her organs, and have since been found in every case of swine 
ague that has come under our notice. 
: Since I have been with the doctor, and after I had become 
;quainted with the method of staining micro-organisms, I have 
j me most of this work that has been done in the laboratory, and 
have succeeded in demonstrating the presence of the micro- 
•ganism in effusions in the abdominal and thoracic cavities, in 
Le blood, in the spleen, kidneys, liver and lungs. This organism 
oval in shape and very minute, requiring a one-twentieth of an 
i ich oil immersion lens to demonstrate it properly. It appears 
) correspond in its morphological and staining characteristics, as 
ell as in various biological phenomena—that is, in its growth on 
jjar. agar, or gelatine and on potatoes—to the one discovered 
id described by Prof. Shutz, the accomplished pathologist of 
le Berlin veterinary school, though there are several clinical, ex- 
aritnental and microscopical points of differentiation in the dis- 
ise, which make us inclined to doubt that the two micro-organ- 
ms are etiologically identical; that described by Shutz seems 
i) be more virulent than the one we have been working with in 
lebraska during the past year; this may perhaps be due to the
