This question is certainly one of the most prominent among those pertaining to the public security, and of all others deserves the first place among the plans relating to both public and private hygiene. In this connection, it is worth while to state that the nations of Europe sometimes permit themselves to be excelled by the inhabitants of countries generally considered as nonprogressive in matters of culture ; for instance, China and Japan.
