Practical physiolog'ical chemistry, J. A. and T. H. Miluoy {New York: Long- 

 viiitix, (I'ri'oi i(- Co., J 90.'/, jij>. XII i COO, ph. 8). — A text-book providing material for a 

 course of apijroximately 3 months. The i)rincipal constituents of the animal Ixjdy 

 and of food stuffs are considered, and both qualitative and quantitative analysis are 

 taken u]). The ajjpendix contains a number of tal)les. 



Text-book of physiological and pathological chemistry, K. Halkowski {I'rac- 

 ticiu)! der 2>Ji;/fiologiscJien und jxtthologisHten Chemie. Berlin: August Hirschwald, 1900, 

 2. ed.,pp. XVI^-310, 2)1. 1, figs^- 10). — This volume is especially designed for medical 

 students and students of physiological chemistry, and takes up botli qualitative and 

 (juantitative analysis. Under the section devoted to qualitative analysis the follow- 

 ing topics are included: Inorganic and physiological-chemical analysis and reactions 

 of metals and acids. Under quantitative analysis: Urine, feces, meat, niilk, bread, 

 l)lood, and similar topics are considered. 



A practical guide to qualitative and quantitative urine analysis and the 

 analysis of gastric juice, F. SKiMUNn ( Praktisclier Lritfaden. dtr (pud'iUttiven, und 

 quantiiativen Harnanalyse nehd Analyse des Mngensaftes. Wiesbadeti: J. F. Bcrgmann, 

 1904, pp. 91; rev. in Oesterr. Chem. Ztg., 7 {1904), No. 2, p. 34). — An introductory 

 text-book and laboratory manual. 



Progress in the field of agricultural chemistry in 1903, A. Stutzer {Chem. 

 Ztg., 2S {1904), No. 14, pp. 149-152). — A Ijrief summary, with numerous references to 

 literature, of investigations relating to soils and fertilizers, plant physiology, plant 

 diseases, feeding stuffs and feeding, and methods of investigation. 



Annual report of the progress in animal chemistry, R. Andreascii and 

 K. Spiro {.TdlireKhcr. Tier-Chem., 32 {1902), j^p. II42). — This contains abstracts of 

 the literature of animal chemistry for 1902, with subject and author indexes. 



Report of the division of chemistry, A. M. Peter {Kentucky Sta. Rpt. 1899, 

 pp. AT-A'A'JX). — This includes analyses of 63 samples of butter, 5 of sorghum, 6 of 

 soils, 4 of tobacco stems, 2 of an egg preservative, 1 of asphalt rock, 1 of petroleum, 

 1 of supposed gold ore, 1 of a ferment for ripening cream, 11 of mineral waters, and 

 43 of numerous species of forage jjlants and grasses. 



Chemical division, B. C. Aston {Nev: Zealand Dept. Agr. Rpt. 1903, App. I, pp. 

 3-24). — This is a report upon the work done dnring the year and includes analyses 

 of 266 samples of butter, 26 of milk and cream, 3 of poultry foods, 4 of limestone, 8 

 of sugar beets, 32 of soils, 40 of waters, and of numerous samjiles of miscellaneous 

 materials. The average water content of the 266 samples of butter from the different 

 districts of New Zealand was 10.33 per cent, only 10 samples showing a water content 

 above 13 per cent. 



Adulterated drugs and chemicals, L. F. Kebler ( U. S. Dept. Agr., Bureau of 

 Clieinhtry Bid. SO, pp. 47). — The author classifies the adulteration of drugs as con- 

 ventional, accidental or incidental, arbitrary to take advantage of certain standards, 

 and intentional; and illustrates each class l^y numerous examples taken from his 

 investigations. A sample of chimaphilla leaves was found to contain 25 per cent of 

 stems. Numerous reagents labeled chemically pure contained varying quantities of 

 impurities. The author considers that the term at present means nothing. Sam- 

 ples of potassium cyanid labeled 98 to 100 per cent pure contained from 22 to 74 per 

 cent of sodium cyanid. A sample of beeswax was found to contain 33 per cent of 

 cassava starch. It is stated that 25 per cent of all turpentine purchased in small 

 packages is liberally adulterated with kerosene. In many instances the goods as 

 delivered were much inferior to the samples submitted. 



A study was made of rose geranium oil which was found to be frequently adul- 

 terated. The sense of smell is considered the most satisfactory procedure available 

 at present for determining the quality f)f tliis oil.
