Lactic Acid in the Treatment of Melanotic Tumors. 
—Vogel reports the successful application of lactic acid in the 
removal of melanotic tumors in horses. In several cases he in¬ 
jected a solution of i : 4 water around the basis of the tumor, 
using as many injections as the size and circumference of the 
tumor necessitates. This treatment results in an artificial di¬ 
gestion of the diseased tissue, gradually loosening the tumor 
from its surroundings. After a few days it becomes possible to 
enucleate the tumor with an elastic ligature or the ecraseur. 
The remaining wound surface is not of a malignant character 
as was expected, but rather shows a tendency to rapid repair 
under influence of antiseptic treatment. 
Foreign Body in the Stomach of a Horse —Eberbach 
reports an interesting post-mortem examination of a horse, which 
had been ailing ten days previous to death and had been treated 
for gastritis. On opening the abdomen the peritoneum appeared 
as reddish-green, and a quantity of bloodish fluid was emptied. 
After removal of the intestines and exposure of the stomach, a 
tumor of the size of a man’s fist was found adhering to the larg-e 
curvature of the stomach. The tumor was flat, of a tough struc¬ 
ture, and microscopically made up of connective tissue with 
plenty of interstices. It was lengthways perforated by a needle, 
the point of which had penetrated the tumor. The stomach it¬ 
self was partially filled with ingesta, and on the corresponding 
place of the tumor the mucosa was dark red and considerably 
swollen, the ear of the needle being exposed. The needle was 
21 cm. long and of the kind used for fastening tobacco-leafs 
grown in that country. As the horse is a careful feeder and 
possesses such a skill in expelling even very small obnoxious 
objects from the mouth, this case is one of the few literally 
known. B. thinks that the needle, being taken up with the hay, 
stuck with its point in the tongue, and the horse being unable 
to expel it, was almost compelled to swallow it.—( B . T. Woch-
