TREATMENT OF PARALYSIS WITH STRYCHNIA, 267 
of arsenious acid, but valuable only so far as corroborating 
the previous tests. 
Having by these preliminary experimental tests obtained 
sufficient evidence of the presence of arsenic, we subjected 
another portion of the viscera to the following method for 
special confirming purposes. This portion was boiled with 
hydrochloric acid for a considerable time, filtered, and then 
some pieces of clean copper wire, hammered flat, were placed 
in the filtered fluid. The mixture was^then boiled in a sand- 
bath on the fire for about forty minutes, and the copper, 
which was now coated with a dark steel-gray crust, was 
removed, carefully dried, and placed in a clean dry test-tube. 
After using precautionary measures to prevent the tube from 
breaking, it was subjected to considerable heat over a spirit 
lamp, which had the effect of causing a thick white sublimate 
to collect on the cool part of the tube. The copper being 
now removed, a little water acidulated, with a drop or two of 
hydrochloric acid was poured into the tube, which with the 
aid of gentle heat dissolved the sublimate. This was now 
treated with ammonio-sulphate of copper, when we had the 
green precipitate as before stated with the neutral solution. 
These, along with other experimental tests, with different por¬ 
tions of the viscera, and with different reagents, together with 
the details of the symptoms, confirmed our opinion that the 
cow had been poisoned by arsenic, and our certificate was to 
that effect. I understand the matter was immediately after 
this placed in the hands of the police, who are making further 
investigations respecting it. 
ON THE TREATMENT OE PARALYSIS IN THE 
HORSE WITH STRYCHNIA. OBSERVATIONS 
ON INDIAN HEMP. 
By " Argus, ” India. 
I have just read Mr. Hoey’s letter on the use of Indian 
hemp in tetanus and paralysis. I have not used this medicine 
myself, nor have I seen it employed in veterinary practice, but 
in the treatment of paralysis I doubt if it will be found so effi¬ 
cacious as strychnia, viz., if the latter be employed judiciously. 
I will give you two or three cases of partial paralysis 
successfully treated with strychnia, which will suffice to show 
that this agent deserves our confidence.
