very extensive sloughing to take place. In this instance he 
had passed his hot iron quite down to the joint formed by 
the dentata and third cervical vertebra, and the dressing also ; 
which was the principal cause of the paralysis which took 
place before death. As the horse proved very restive when 
dressed, some of the agent employed fell on the ground. It 
was picked up by Mr. Hodkinson, and afterwards given to me, 
and I have enclosed some of it for your inspection. The 
same is very generally employed by many of the old school 
for fistulous affections, the removal of warts, &c., and some- 
times a solution of it is resorted to for mange. 
[Mr. Cox is right in his conjecture. The agent sent to 
us is the suljphuret of arsenic . A few grains of it being dis- 
solved in dilute hydrochloric acid, and a slip of copper-foil 
afterwards introduced, aided by heat, it soon became covered 
with a whitish alloy. Being dried on bibulous paper, and 
the metal heated in another test tube, the deposited metallic 
arsenic became oxidized, and this being dissolved in distilled 
water, the solution gave the characteristic precipitates with 
the usual liquid re-agents. In like manner, a few grains 
dissolved in caustic potash and diluted, furnished similar 
results.]

Dear Sirs, — As we are now ascertaining the action of 
Arnica Montana on the horse, it has struck me that the 
following, translated from Hering’s “ Arzneimittel,” might 
be worthy a place in the Veterinarian. 
Yours very truly.

ARNICA MONTANA. 
This plant is indigenous to the mountain range of medium 
height in Germany, as the Taunus mountains near Frankfort. 
The Germans call it the “fall plant” (fallkraut), from its 
being generally used for bruises from falls. This Dr. Voelcher 
informs me. It has a stem one to two feet high, with com- 
posite flowers, which are gathered from June to August.
