    CHEMISTRY OF MAN. PLE APAAAAAD DAO INTRODUCTION. THE proximate constituents of the animal body may be divided into two great classes, the mineral and the organic; each of which admits of several sub-divisions. I. MINERAL CONSTITUENTS. The Mineral Constituents may be advantageously classed in three groups, comprising, 1, Those which are of service in the animal body, in consequence of their physical properties; 11, Those which effect important objects in the system by their chemical actions ; and 111, Those which, being only incidentally present, may be eliminated without exerting any unfavorable effect on the economy. CLASS I. CONSTITUENTS USEFUL BY THEIR PHYSICAL PROPERTIES. 1. Water. This substance is so universally diffused, and its uses are so obvious as to render any observations unnecessary. 2. Phosphate of lime, in the importance of its physical proper- ties to the animal organism, undoubtedly ranks next to water. Phosphate of lime or, as it is often termed, bone-earth, consists of 8 eq. of lime and 3 eq. of phosphoric acid; its empirical formula therefore is 8 Ca O + 3 PO,; but there can be no doubt that ]
