lation with the toxin^ remembering furthermore that such 
horses always died, for the 6 mg. of toxin constituted the fatal 
dose, it was easy to substantiate or refute Behring’s claim that 
his antitoxin could cure tetanus already developed. Of 33 
animals receiving the fatal dose of tetanus toxin, and receiving 
Behring’s curative dose (5 c. cm.) of antitoxin^^ receiving this 
dose moreover intravenously according to Behring’s directions, 
upon the appearance of the first symptoms of tetanus, all died, 
the animals treated with antitoxin dying sometimes sooner than 
the animals, that received the fatal dose only, but no antitoxin 
at all. Whether the Pasteur or Behring antitoxin be iised, after 
the first symptoms of tetanus once set in, the antitoxin cannot 
control the course of the disease. Nay, what is more to the 
point, even if the tetanus antitoxin be injected 24 hours previ¬ 
ous to the onset of the first symptoms. Even if more than the 
curative dose be injected, even if it be injected into the jugular 
(which can easily be done before the incubating period or period 
of inoculation to the first day of symptoms break out is known 
to be from five to seven days and usually six days) the disease 
cannot be controlled in the least. When made 4^ hours before 
tetanus may be avoided. If immediately following the injectiofi 
of the toxin, the antitoxin be injected in small doses subcutane¬ 
ously no tetanus ensues. Taken in all, the prevention or im¬ 
munizing power of tetanus antitoxin is unlimited when cura¬ 
tive power is absolutely nil—{Deutsche ThierarzU Wock.)

Potassium Iodide eor Champignon [By M. J, Treacy^ 
Vet, U. S. Army, Fort Meade, South Dakota~\,^ —The author 
narrates that last April he saw a horse used for livery purposes, 
emaciated, lame from an immense unilateral champignon. 
After draining off the effusion its base measured 17 inches by 8. 
There was no discharge, and no pus found upon exploration 
with trocar and canula. His physical condition was looked 
after by smoothing irregular teeth and administering a tonic, 
consisting of 2 per cent, acid sol. arsenic, 3 x ; tinct. Rrri chlor.,

one drachm potash iodide every evening. Apply hose to scrotum 
for one hour night and morning; gentle exercise two hours 
daily. There was no visible decrease for ten days, after which 
the tumor rapidly reduced, the horse now resuming severe work,j
