Text-book of hygiene; a comprehensive treatise on the principles and practice of preventive medicine from an American stand-point . sometimes becomes very foul and objection-able. The Jennings, Demarest, and Hygeia are types of thisclass.

The hopper-closet consists of a deep earthenware or enameled HOUSE-DRAINAGE. 169 iron bowl, with a water-seal trap directly underneath.
