    food, and not excreted at once with the faeces, are absorbed and deposited in some tissue or organ, of which, however, they form no necessary part. In the same manner arsenic and lead, being absorbed, may be deposited in the liver and other parts. This view is confirmed by the fact observed by Heller, that although copper is frequently present in the bile of adults, yet it is never found in that of infants (ix. vol. ii. p. 321). The researches of Cattanei di Momo also seemed to prove that neither copper nor lead exists in the bodies of new-born children or infants (xxv. 1843-4, p. 3). CHAPTER II. STRUCTURAL COMPOSITION OF THE HUMAN BODY. The component substances of the body are commonly divided in fluids and solids. The fluids are, 1st, formative fluids, from which are derived the materials for the formation of the solid tissues; and, 2nd, secreted fluids, which are separated from the tissues and the blood, through, speaking generally, the operation of special organs, such as cells arranged in glands or membranes. So httle can be said that would apply to all the members of either of these classes of the fluids, that a general description of them would be useless; they will therefore be considered in their several more appropriate places. — [See chapters on Blood, Lymph, Chyle, the several Secretions, etc.] Among the solids of the body, some appear, even with the help of the best microscopic apparatus, perfectly uniform and simple: they show no trace of structure, i.e., of being com- posed of definitely arranged dissimilar parts. These are named simple, structureless, or amorphous solids. Such are the
