VETERINARY JURISPRUDENCE.

a new bath as often as directed, by which deviations, it was 
contended, that the strength had accumulated. Mr. Froom was 
a skilful and scientific chemist : his composition resembled that 
of Mr. Bigg, but was more chemically mixed. Bigg’s compo¬ 
sition had been in great repute for many years. 
Several sheep farmers here gave evidence of their having 
used Froom’s composition without evil consequences. 
Mr. Froom himself stated, that he had been a chemist for 
many years, and his father before him from 1799. Had sold 
Bigg’s composition for some years. In May 1849. Bigg gave 
notice that he should discontinue his agency, and supply the 
article direct; he afterwards wrote, requesting him to resume 
the agency, but he (witness) had commenced making his own, 
as follows :— 
51b. Arsenic, 
51b. Sulphur, 
201b. Soft Soap, 
^lb. Salt of Tartar. 
Had not varied the recipe in 1849, 1850, or 1851. The 
soap was warmed, poured into a mortar, and the ingredients 
rubbed together. He made 301b. at a time. He had seen 
similar formulse in standard works on veterinary medicine, 
some of which contained more arsenic than his own. He had 
furnished some of his own and some of Mr. Bigg’s composition 
to Dr. Hulme for analysis. Believed there was very little 
difference; had not observed solid particles of arsenic in 
either. 
Dr. Hulme, of Exeter, had received the samples for analysis, 
and had sent a portion of each to Mr. Herapath. The following 
was the result:— 
Froom’s. 
Sulphur . . . . 
Arsenic . . . . 
Potash . . . . 
Oil and fat . .

Bigg’s, therefore, contained much more arsenic than 
Froom’s. There was no formation of arsenite of potash in 
either, as, mixed with sulphur and fat, there would be no con¬ 
tact. Putting eight pounds to forty gallons of water, he was 
of opinion that arsenite of potash would not be formed. Adding 
eight pounds of Bigg’s composition to forty-three gallons of 
water, it would be much stronger than the other; both would 
deposit a sediment. In Bigg’s there would be more arsenite of
