CLASSIFICATION OF POISONS. 
23 
§ I9-] 
B.—ACIDS AND ALKALIES. 
1. Sulphuric acid. 
2. Hydrochloric acid. 
3. Nitric acid. 
4. Potash. 
5. Soda. 
6. Ammonia. 
7. 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 SEPAR¬ 
ATED BY DISTILLATION 1 FROM EITHER NEUTRAL 
OR ACID LIQUIDS. 
1. Hydrocarbons. 
2. Camphor. 
3. Alcohols. 
4. Amyl-nitrite. 
5. Chloroform and other anaesthetics. 
6. Carbon disulphide. 
7. Carbolic acid. 
8. Nitro-benzene. 
9. Prussic acid. 
10. 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. 
D. —ALKALOIDS AND POISONOUS VEGETABLE PRINCIPLES 
SEPARATED FOR THE MOST PART BY ALCOHOLIC 
SOLVENTS. 
DIVISION I.— Vegetable Alkaloids. 
1. Liquid volatile alkaloids, alkaloids of hemlock, nicotine, 
piturie, sparteine, aniline. 
2. The opium group of alkaloids. 
1 Distillation, that is, at ordinary barometric pressure; by the use of superheated 
steam under low pressure, it has been shown that a large number of substances not 
ordinarily considered volatile may be distilled.
