The insect powder is macerated 4 or 5 days in the alcohol and 
shortly before using the maceration is mixed with the soda solu¬ 
tion; the latter is intended for the destruction of the cutin cap¬ 
sule of the egg. The horse is first clipped and the whole body 
sponged with the fluid. If the hair is not removed, particular 
care should be taken that the application impregnate the roots 
of the hairs. In this manner a single sponging not only kills 
the insect, but also the greater number of the eggs. The re¬ 
mainder die in the course of a few days.— (Berliner Tieraerztl.

The Treatment of the Cutaneous Inflammation 
Caused by the Filaria Irritans [Anton V. Toth]. — For 
some years past the author had occasion to observe and treat 
many cases of cutaneous inflammation caused by the Filaria Irri¬ 
tans appearing in the withers and shoulders of horses. 
In the beginning small round nodules, about the size of a 
pea, are observed on the shoulders and withers, the hair stands 
erect on. these spots, it soon falls off; the part becomes crusty 
and dry. Soon the scab falls away, leaving a small ulcerated 
surface, in the center of which shot-like elevations appear. In 
these little shot-like nodes the larva of the Filaria can be distin¬ 
guished by the aid of the microscope. In extensive affections 
of this nature, which were treated surgically and medicinally, 
for instance, with carbolic acid, creolin, corrosive sublimate, 
iodoform, even the actual cautery, little success had been 
attained, for under the old crusts nodules appeared anew. 
Finally the author succeeded in discovering a remedy: an ar¬ 
senical paste which had given good results in all cases. The 
prescription is as follows: 
3 ? Acido Arseniosi Pulverisati. 5.0 
Farina Secalis . 25.0 
Aquae Destillatae . q. s. 
Misc. fiat pasta.
