A generic name for all substances which, when introduced into the animal economy, either by cutaneous absorption, respiration, or the digestive canal, act in a noxious manner on the vital properties or the texture of organs. Hence we speak of fever poison, cholera poison, &c. Poisons exist in the three kingdoms of nature; but those which proceed from animals are often called venoms, as the venom of the viper, scorpion, tarantula, &c.; whilst those that are the products of disease have the name vims. In common parlance, therefore, poison is restricted to deleterious articles, furnished by the mineral and vegetable kingdoms. Orfila has divided poisons into four classes. 1. ACRID, IR,RITATING, CORRO'SIVE, or ESCHAROT'IC, such as the concentrated acids and alkalies; mercurial, arseniacal, cupreous, and antimonial compounds, cantharides, &c. 2. NARCOT'IC; those that act particularly upon the brain; as hyoscyamus, opium, &c., but without inflaming the organ with which they come in contact. 3. NARCOT'ICO-ACRID or ACRO-NARCOT'IC ;-those that act on the brain, but, at the same time, irritate the parts to which they are applied; as aconite, belladonna, &c. 4. SEPTIC or PUTRES'CENT; - those furnished by the animal kingdom. See Venom and Virus. Various classifications, of a similar character, have been recommended by different toxicologists; but they are liable to the objection, that they throw substances together whose physiological action on the system is very different. It is, indeed, difficult to avoid unnatural compression of matters into places not properly belonging to them, in all such arrangements. The following table, which exhibits a coup d'oeil of the chief poisons, with most of the circumstances of importance connected with them, it not free from these objections. The most energetic poisons are used therapeutically, and often with considerable advantage. They have, of course, to be administered in extremely small doses, to avoid producing poisoning.

The term has various shades of meaning dependent upon the relation in which it is employed. P. may be defined as a substance, organic or inorganic, originating in the organism or introduced from without, artificially or naturally formed-not organized, e. g., bacteria-which through its chemical nature under certain conditions so influences organs that the health or relative wellbeing is thereby injured, temporarily or permanently. List of poisons and their antidotes, see in appendix.
