    PREPACE FO, FORMER EDITION. Tuis book was originally compiled as a handbook for prac- tical work in Physiological Chemistry at University College, London, since no single text or class book covered the complete course, or treated Physiological Chemistry as part of the subject of organic Chemistry, or even as an_in- dependent subject. The present book must still be regarded mainly as a compilation. It represents an attempt to give to the worker a nearly complete statement of the whole subject. Each section has a short explanatory summary of the essential points, so as to connect the various sections together. The essential points are illustrated by the practical experiments, which are printed in different type. The illustrations are also compiled from various sources. These are mentioned underneath each figure. The illustra- tions of apparatus not so mentioned have been drawn from my own sketches. For those of the osazone crystals, haemin, and tyrosine, I am indebted to Miss V. G. Sheffield, who has also kindly helped in reading the proof sheets. In most physiological chemistry laboratories the strengths of the reagents employed are very various, e.g. dilute acetic fememay net per cent, or 2 percent: or. 5- per cent., or even 10 per cent. In order that all workers may employ a reagent of standard concentration, a list of reagents has been carefully drawn up and is appended.
