One chapter is devoted to "Soap Machinery," and another to the "Technology of Soap-Making." This subject, always difficult to treat in a manual, gives the novice a clear view of the principles and practice of soap-making. In the analysis of soap the author shows himself to be entirely at home, writing from his own experience. Indeed, a single brief chapter of more use to the soap chemist can hardly be found anywhere. The practice of calculating the alkali combined with fatty acid as Na or K instead of the time-worn Na,0 and K,O, is to be commended; for, besides being the modern and rational view of the composition of alkaline salts, it allows the fatty acid to be entered in the analysis as such, instead of as hypothetical anhydride, the total, on footing up the analysis, being only a trifle over 100, due to the acid hydrogen of the fatty acid. A very brief chapter is given to the recovery of glycerine from lyes, and an appendix is added with the common specific gravity and hydrometer tables. E. TWITCHELL. BOOKS RECEIVED.
