The latest "discovery of the germ of smallpox," if established, is a stimulus to increased efforts along such lines. Animal and vegetable forms are both proved guilty before the bar of the scientific investigator. The germ of typhoid fever grows well in milk. The germ may enter the milk as dry dust from any one of many contaminated sources, or through water in which the milk-containing vessels are washed. In cases of dishonest milkmen, from the water used to dilute the milk. Numerous epidemics of typhoid fever have been traced to milk as their source, where only those using milk from one farm or from a certain milkman have been affected.

It is not always easy nor possible to find the source of single cases of this or any disease, for the infectious germ, carried as dust, may lodge on any article and be thus carried to the mouth by food or by hands. infection Oysters, fattened on sewage-polluted water, have r oysters carried the germ to persons eating them.
