Neverman concludes by saying that Schmidt’s treatment will 
prove to be a boon to country veterinarians and agriculture at 
large. i- 
Foot-and-Mouth Disease Serum. —According to reports 
of several district veterinarians the new agent “ seraphthin,” 
prepared by the Hochteo Farbweske for the immunization of 
animals against foot-and-mouth disease, has not proven a relia¬ 
ble protection lymph. 
Chemical Reaction of the Meat of Slaughtered 
Animals. —Edelman and Mack have undertaken a series of 
experiments to determine the normal chemical reaction of the 
meat of slaughtered animals. Of 1876 carcasses, so tested, 
8.6 per cent, showed an alkaline reaction, traceable to various 
diseases, injuries from transport, weakness of heart with insuffi¬ 
cient bleeding, emaciation, hog-cholera, etc. A very fat hog 
which appeared healthy, and which during a rather scanty 
bleeding, was lying on the left side, showed an alkaline reac¬ 
tion of the meat of the left side and an acid reaction on the right 
side The acid reaction of healthy meat was found to take place 
from three to six hours after slaughtering, but even here con¬ 
siderable variations have been noticed. The experiments will 
be continued to determine, if possible, whether a simple test 
with litmus paper can be safely used to discriminate between 
wholesome and unwholesome meat in the market halls. 
BELGIAN REVIEW. 
Mammary Actinomycosis of Swine \^By J. Hamoir \.— 
In this animal, though muscles and tonsils are frequently the 
seat of actinomycotic growths, the mammae are still more com¬ 
monly affected, where they present themselves under peculiar 
conditions. Ordinarily located in the median mammge, they 
begin by an induration at the basis of the teat, gradually in¬ 
creasing and soon reaching the size of the fist, spreading to the 
surrounding glands without contracting adhesion to the con¬ 
tiguous ventral skin. The growth is then bosselated, lobulated,. 
covered with varicous skin and has the consistency of a fibroma. 
When ulcerated, the ulcer is fungous, of various sizes with well 
defined borders. The tumor is not painful and its presence does 
not seem to interfere with the general health. It is not very 
vascular and is easily enucleated. The treatment is surgical, and 
if properly done there is but little danger of return. It consists 
in the extirpation of the tumor by exposure of the growth through
