A register of proprietary medicines, etc., is established. The
object is to protect the public against quack remedies.
=Notification of Poisoning.=--Every case of poisoning which occurs in
any industry (lead, arsenic, anthrax, etc.) must be notified by the
medical attendant to the Chief Inspector of Factories (Factory and
Workshops Act, 1895).
III.--ACTION OF POISONS; CLASSIFICATION OF POISONS
=Action of Poisons.=--They may act either locally or only after
absorption into the system.
1. _Local Action_, as seen in (a) corrosive poisons; (b) irritant
poisons, causing congestion and inflammation of the mucous
membranes--_e.g._, metallic and vegetable irritants; (c) stimulants or
sedatives to the nerve endings, as aconite, conium, cocaine.
2. _Remote Action._--This may be of reflex character, as seen in the
shock produced by the pain caused by corrosive poisons, or the poison
may exert a special action on certain structures, as belladonna on the
cells of the brain, strychnine on the motor nerve cells of the spinal
cord.
3. _In Both Ways._--Certain poisons, as carbolic or oxalic acids, act in
this way.
Age, idiosyncrasy, tolerance, and disease, all exert modifying
influences on the action of a poison.
