    57. As it is much easier to obtain the measure than the weight of urine passed in a given time, the following table becomes of use in enabling us to calculate the weight of the urine (in grains) from its bulk. A pint of distilled water weighing 8750 grains. Table 2. Specific Weight Specific Weight gravity. of one pint. gravity. of one pint, j Grains. Grains. 1-010 8837 1023 8951 1-011 8846 1-024 8960 1-012 8855 1-025 8968 1013 8863 1-026 8977 1-014 8872 1-027 8986 1-015 8881 1-028 8995 1-016 8890 1029 9003 1-017 8898 1-030 9012 1-018 8907 1-031 9021 1-019 8916 1-032 9030 1-020 8925 1-033 9038 1-021 8933 1-034 9047 1-022 8942 1-035 9056 58. The following example will be sufficient to point out the mode of using the preceding tables. Ex. : A patient passes in 24 hours 2 J pints of urine of the specific gravity 1*020; what is the weight of solid matter thus excreted by the kidneys ? 1000 grains of urine, specific gravity ]*020, hold dis- solved 46-6 grains of solids (Table 1), and a pint will weigh 8925 grains (Table 2) y then, 8925 x 46-6 =415*9 grains of solids in a pint; iooo r and 415-9 x 2j = 1039*72 grains, being the total quantity present in urine of 24 hours. 59.
