The book, however, has been out of print for nearly a year owing to pressure of other matters, and the time required for investigation of new processes or modifications of old ones. It will be seen that considerable alterations and additions have been made in various sections, so as to bring the work up to date as closely as possible. The sections thus altered, aiict pthers entirely new, comprise chiefly the articles on Calibration of I nstruments, the Kjeldahl process, Boric A cid, Hydrofluoric A cid and Fluorides, A rsenic, Chromium, Copper, Cyanogen and Cyanides, I ron, Lead, Manganese, Mercury, Nickel, Phosphoric A cid, Sugar, Sulphur and its compounds, Tannin, Zinc, Oils and Fats, and Urine. -A srespects the volumetric method as applied to many organic substances, and the action of modern indicators in such work, nothing has been attempted, partly because the results hitherto obtained have not been altogether satisfactory, but mainly because this subject comes specially within the scope of my friend A. H. Allen swell-known work on Organic A nalysis, and it cannot in my opinion be left in better hands. My thanks are especially due to Mr. W. B. Giles, F.I.C., for his original article on the estimation of Hydrofluoric A cid, and for the benefit of his long practical experience in the examination of Sulphur Compounds and Phosphoric A cid.

The last edition has been required so speedily that I am personally a little worried in not being well prepared for a new issue. However, there are many valuable additions and a few deletions in the present edition. There are so many workers at volumetric processes now that it is simply impossible to verify all suggested methods, and I have to acknowledge very willingly that the short abstracts occurring in the Chemical Society s Journal the Journal of the Society of Chemical I ndustry, the Analyst and Chemical Newny have supplied me with a large amount of information, and some of which I have quoted almost verbatim. This abstract work is so well done in many cases that all the essential matter is contained. My desire has always been to keep a Handbook as a portable and convenient reference book. In the present edition the actual number of pages is less than the last, but the size of page has been slightly enlarged, and, therefore, the matter is considerably more than formerly.
