HYPODERMA EQUI, LARVA OF AN INSECT DIPTERA. 
A species of (Estrus at times causes great inconvenience 
in the horse. In one case, a well-bred horse, having always 
been thoroughly clothed up, had a tumour on the withers, 
just in front of the roller. It was much inflamed, hot, and 
painful. After several days of treatment, a black speck was 
perceived in the centre, with a small opening filled with pus, 
through which was seen the posterior extremity of a larva, 
similar to that infesting the ox, only much smaller. When 
the larva had been extracted, the tumour healed without any 
further care. According to M. Joly, professor of zoology, 
this larva forms a particular species, to which he has given 
the name of Hypoderma equi. They are rare in the south, 
but more common in the north of Belgium, also in Holland, 
and on the shores of the Baltic and the North Sea. 
TRANSMISSION OF TETANUS FROM ANIMALS TO MAN. 
By M. Betoli (‘ Annali Universali di Medicina’). 
An Italian physician, practising in the Brazils, relates the 
following fact:—A rich proprietor ordered a bull to be cas¬ 
trated. The operation was, perhaps, badly performed, and 
tetanus supervened, and the animal died in convulsions. The 
proprietor ordered it to be buried, but the slaves secretly ate 
some of the meat. Immediately after, two of them were 
seized with tetanus so horrible that in a short space of time 
they died. Two days after another was attacked; he was 
immediately sent to the nearest town. When he arrived he 
was so bad that he could not tell his name, and he died forty- 
eight hours after the attack, notwithstanding the efforts of 
Dr. Heredia to save him. On the same day another com¬ 
panion of the above, also attacked with tetanus, entered the 
hospital; but this one probably had not eaten so much of the 
diseased meat, or perhaps "was of a stronger constitution, for 
he was less violently attacked, and there was some chance of 
saving him. Here are then two cases of almost sudden death 
from having eaten the flesh of an ox affected with tetanus, 
although no medical practitioner has considered it up to the 
present time a transmissible malady. There is nothing (ob¬ 
serves M. Betoli) so deceptive as a single fact. The disease 
<*f these slaves was certainly tetanus, as M. Heredia has
