The salt is a corrosive irritant poison when taken internally.
A good palliative is sweet oil; this will allay any corrosive irritation of the throat and stomach, and at the same time cause vomiting.
The post-mortem appearances will be those of corrosive poisoning.
The result is to prevent the local corrosive action of the poison and to prevent absorption of the metals.
If it be exposed to damp, to sea-water or to corrosive influences of any kind in contact with another metal, or if it be mixed with another metal so as to form an alloy which is not a true chemical compound, the other metal being highly negative to it, powerful galvanic action will be set up and the structure will quickly deteriorate.
