    cording to 38 (i. The albuminous residue is incine- rated ; the earthy phosphates are then left, and may be separated according to 4-1. The quantity of chlo- rine is calculated from the chloride of silver, the sul- phuric acid from the sulphate of baryta, the phos- phoric acid as the difference between the quantity of oxide of iron corresponding to the pure iron used and the mixture of phosphate and oxide. By calcu- lating the quantity of the bases corresponding to the acids, and comparing these quantities with those found by the separate platinum analysis of the residue after the separation of the acids, the amount of the bases may be controlled. The process may be some- what abbreviated by ascertaining the amount of albu- men from a separate portion, and incinerating the second at once to obtain the ash. The following mean of two analyses by Lecanu and Becquerel and Rodier, will serve to give a general idea of the quantities of the various constituents of the blood, although these are so various that no defi- nite proportions can be fixed :— Water 78-2867 78-5050 Fibrine 0-2832 0-2200 Albumen 6-7252 6-9950 Fat 0-5155 0-1610- Seroline 0-0020 Phosphorized fat 0-0476 Cholesterine ... 0-0089 Saponified fat ... 0-1025 Corpuscles 12-6313 13-4150 Alcoh6licextractive 0-1855 1 (Extractives).
