TETANUS.
Tetanus or lockjaw is not infectious, but is conveyed to man by the inoculation of a wound by dirt or earth which contains the tetanus bacillus. For this reason it is more apt to follow injuries to the hands or feet. Extreme cleanliness of wounds is the only practicable preventive means. Little is known of the history of the tetanus bacillus outside the body; and as to what soils contain it most abundantly. Wounds contaminated by horse manure appear to be especially dangerous.
