    25. Amount of Water Consumed Yearly by an Adult.— An adult drinks about fifteen hundred pounds of water jearlj; and throws off through the various waste-gates nineteen hun- dred pounds. The difficulty of accounting for the four hun- dred pounds has led some to suppose that water is formed in the system by the union of oxygen and hydrogen. 26. Common Salt in the Body.—The salts that have been enumerated, are found in almost every part of the body. Com- mon salt (Chlorid of Sodium) is found in every fluid and solid, except enamel. The whole amount in man i3 277 grains. It subserves many important uses. 27. Carbonate and Phosphate of Lime, &;c.—Carbonate of lime exists in considerable quantity in the bones, along with a much larger quantity of the phosphate of lime, and a small amount of phosphate of magnesia, and of fluoride of calcium. These salts, except the fluoride, arc found in most other parts of the body. 28. A c i d S, S a 11 s, & C.—Most of llic acids aiid salts, the neu- tral nitrogenous compounds, the sugars, the fatty and sapona- ceous compounds, exist, or are formed in the fluids of the body, and though numerous (forty-two in all), their quantity is comparatively small. They are mostly formed by disassimi- lation in the body, and hence only their elements need to exist in our food. 29. Sugar in the Body.—Only two kinds of sugar exist, or are formed in animals. Grape sugar is found in the liver, in some of the veins, and other organs. In the disease called Diabetes, its quantity is very much increased, and, in fact, an excess of sugar in the system is a sign of serious derangement. 30. Fats in the Body.—The fatty principles, cholesterine, oleine, etc., exist in the body in cells, in chemical combina- 25. How much water docs a ihan consume in a year?
