434 REVIEW.—A VETERINARY TOXICOLOGICAL CHART. 
Chart. We will, however, take the Corrosive Sublimate—a dan¬ 
gerous medicine, and by which many horses have been destroyed. 
Hydrargyri BiCHLORIDUM, Bichloride of Mercury, Corro¬ 
sive Sublimate. 
Symptoms.—T he effects which follow the administration of 
large doses of this salt resemble those which supervene when the 
mineral acids have been given, except that, generally, super-purga¬ 
tion is present, and the faecal matter is profuse and highly offen¬ 
sive. Its solubility renders it more energetic than arsenious acid, 
although it is not so frequently had r(5Course to for poisoning. 
‘^The protochloride of mercury, calomel, when incautiously given, 
has also caused death, by inducing inflammation of the mucous 
lining of the intestines, accompanied with violent purging and 
tenesmus. 
‘‘ Treatment. —The white of eggs suspended in water, the al¬ 
bumen of which renders the bichloride of mercury insoluble; or 
large quantities of wheat-flour, or milk. Iron filings have also 
been advocated, which, reviving the metallic mercury, may be ex¬ 
pelled by purgatives. A free use of diluents is necessary. The 
treatment of the salivation, which sometimes supervenes, consists 
in exposure to cool air, the exhibition of saline purgatives, and 
nourishing diet. 
Morbid Appearances. —These would closely resemble the 
effects produced by the above agent, the mucous lining of the ali¬ 
mentary canal being intensely inflamed throughout, its texture de¬ 
stroyed, and in parts corroded. The disorganized tissue often con¬ 
tains the poison, which it yields by analysis. 
“ Tests.— Lime-water, which throws down an orange-yellow 
precipitate, the hydrated hinoxide of mercury. 
“ Iodide of potassium, which gives a beautiful scarlet com¬ 
pound, the hiniodide of mercury. 
“ Protochloride of tin, which first affords a whitish precipitate, 
the protochloride of mercury ; and, on adding more of the test, a 
greyish-black powder is formed, which consists of minutely divided 
metallic mercury. 
“ Sulphuretted hydrogen, which gives a blackish compound, a 
sulphuret of mercury. 
‘‘ To these may be added the test by reduction, the reducing 
agent being the protochloride of tin, assisted by heat. 
Albumen is not now relied on as a re-agent.” 
We have only one thing of which to remind the author,—that 
when cattle practice is fully and fairly taught at the Veterinary 
College, and more is known of the effect of different medicines on 
cattle, we shall look to him for an extension of this Chart to every 
animal that can be injured or benefitted by man. . Y.
