day the puppy seemed comfortable, began to suck his mother, 
and in a few days was cured.— (Rec. de Med. Vet.) 
Melanotic Tumor in a Mare [M. Caguy\ .—This case 
is reported as a record for an attempt at treatment by interstitial 
injections of lactic acid. It relates to a mare, aged 15, which 
became lame on the left hind leg. She was in good condition, 
no indication of pain, and stood well on both legs. After trot¬ 
ting ioq meters she showed no trouble, but if the distance was 
increased to 600 or 700 meters she became lame and gradually 
limped more and more to such an extent that after some time 
the lameness was such that she could not go any further and 
she was ready to fall. After one or two minutes of rest she 
would be able to resume work. During the attack the leg 
would be cold, the muscles of the side hard, tetanic like ; res¬ 
piration hard, nostrils dilated, seeming in great pain. After the 
attack the heat would return to the leg and the muscles resume 
their suppleness. By rectal exploration a tumor as big as the 
fist was found, attached to the sacrum, and involving the left 
iliac blood-vessels. The pulse, easily felt above the tumor, is 
imperceptible below it. The diagnosis was sure—a melanotic 
sarcoma interfering with the circulation of the left hind leg. 
Abandoned by the owner, it was decided to try interstitial in¬ 
jections of lactic acid, already mentioned, to arrest the growth 
and promote the melting of subdermic melanoma. These were 
made in the mass of the tumor, through the rectum, carefully 
disinfected. Five injections of one cubic centimeter each of 
pure lactic acid were made at various points of the tumor. At 
first the animal did not seem to suffer, except from slight colics, 
but after a few days the leg began to swell, standing upon it be¬ 
coming more and more painful and difficult, and the size of the 
tumor increased, and the animal was slaughtered. The diagnosis 
was confirmed at the autopsy. A number of melanotic growths 
were found beside the one spoken of above. At the five points 
of puncture there were five cysts, containing eight or ten cubic 
centimeters of citrine serosity. Around them the tissues of the 
tumor were softened, of sticky consistency, and colored in black. 
With time, perhaps, the tumor having undergone this change in 
its whole structure, might have been resorbed and recovery or 
an improvement be obtained.— [Bullet, de la Soc. Cent.)
