REVIEW.

minutes, and especially in such places as appear most affected; 
after which the animal is to be immersed in a warm bath. 
The action of the remedy is at once apparent — all the mangy 
places having turned bright red. The animal is continually 
licking himself, but no longer scratches. 
On the second day, the redness is less apparent, the ulcera- 
tions, if there are any, contract, and become on the third or 
fourth day covered with incrustations and cicatrized. The 
mangy vesicles dry up, and soon afterwards are replaced by fur- 
furaceous pellicles which are not long before they peel off. 
On the sixth day, the dog is washed with soap or a weak 
solution of carbonate of potass, when, if it were a recent mange, 
it will be found to completely have disappeared. Though, if it 
be an inveterate disease, a fresh rubbing becomes necessary. 
During this treatment it is a good plan to employ purgatives. 
M. Prange is of opinion that sulphur, whose antipsoric virtue 
is acknowledged, united with the tannic acid contained in the 
gall-nut, whose astringent action is so powerful, are the two 
agents operative in the cure. In fact, he acknowledges his re- 
medy to be no better than many others used for the cure of 
mange ; but he gives the preference to it over ointments re- 
quiring considerable time and care in the effective use of them, 
as well as over baths, which are not at all times to be had, since 
bathing places are not in all situations at hand. 
“The remedy I recommend,” says M. Prange, “is not new, 
though it is but little known to veterinary surgeons. It is not, 
that I know of, effectual in every stage or form of mange ; only 
in the two first stages is it that it can be used with certainty of 
success. As for chronic or inveterate mange, we must have re- 
course to more potent applications than the oleo -sulphur e-tan- 
nique .” 
Willing to give M. Prange a fair trial of his remedy, an in- 
vitation was given to him to attend at the Veterinary College at 
Alfort to witness trials being made of it. Of nine dogs ex- 
perimented on, 
One died of entero-pneumonia. 
One resisted the treatment, and was subsequently cured by 
baths of sulphate of potass. 
Two, however, on which the same baths had failed, were cured 
by it. 
Four others yielded to its influence. 
One alone, affected with diseased condition of the bulbs of 
the hair, caused seemingly by a sort of acarus, resisted, not only 
to M. P range’s remedy, but to all other antipsoric preparations, 
even the most energetic. 
To sum up our observations, the Committee are of opinion —
