Suffocation is the direct cause of death therefore, in hanging, drowning, and any other method; which is adopted for preventing fresh air from entering the pulmonary organs. Suffocation, therefore, may result from being overlain by any animal—such as a cat or dog—which is permitted to have free communication with bedrooms, nurseries, etc., in which young children are sleeping. It may also arise, and frequently does, front breathing an atmosphere which is largely impregnated with carbonic acid gas, and, as is well known, where persons are immured from the falling of soil when excavating mines, tunnels, or other structures, and in children who are overlain by their parents.
