- Carbon monoxide.
- Chlorine.
- Hydric sulphide.
B.—ACIDS AND ALKALIES.
- Sulphuric acid.
- Hydrochloric acid.
- Nitric acid.
- Potash.
- Soda.
- Ammonia.
- Neutral sodium, potassium, and ammonium salts.
In nearly all cases of death from any of the above, the analyst, from the symptoms observed during life, from the surrounding circumstances, and from the pathological appearances and evident chemical reactions of the fluids submitted, is put at once on the right track, and has no difficulty in obtaining decided results.
C.—POISONOUS SUBSTANCES CAPABLE OF BEING SEPARATED BY DISTILLATION FROM EITHER NEUTRAL OR ACID LIQUIDS.
- Hydrocarbons.
- Camphor.
- Alcohols.
- Amyl-nitrite.
- Chloroform and other anæsthetics.
- Carbon disulphide.
- Carbolic acid.
- Nitro-benzene.
- Prussic acid.
- Phosphorus.
The volatile alkaloids, which may also be readily distilled by strongly alkalising the fluid, because they admit of a rather different mode of treatment, are not included in this class.
