BOOKS RECEIVED 



The BiocHEMiCAL Bulletin promptly acknowledges here the receipt of 

 publications presented to it. Reviews are matter-of-fact Statements of the 

 natura and Contents of the pubHcations referred to, and are intended solely to 

 guide possible piirchasers ; the wishes or expectations of publishers or donors of 

 volumes will be disregarded, if they are incompatible with our convictions re- 

 garding the interests of our colleagues. The sizes of the priiited pages are 

 indicated, in inches, in the appended notices. 



An introduction to the chemistry of plant products. By Paul Haas 

 (lecturer on chemistry, Royal Gardens, Kew) and T. G. Hill (reader in 

 vegetable physiology, Univ. of London). Pp. 401 — 4X7; $-2.25 net. Long- 

 mans, Green and Co., 1913. 



Excellent discussion of the chemistry and biological significance of many 

 of the most important plant constituents. Besides extended treatment of carbo- 

 hydrates, lipins and proteins, chapters are devoted respectively to glucosides. 

 tannins, pigments, nitrogenous bases (alkaloids, ptomaines, purins), colloids and 

 enzymes. Methods of preparation, detection and quantitative determination are 

 numerous and well described. Good snbject index. The most valuable recent 

 contribution of its kind to phyto-chemistry. Strongly recommended to biological 

 chemists generally — to botanists in particular. Gies. 



Practical physiological chemistry. By Sidney W. Cole, demonstrator of 

 physiology, Trinity College, Cambridge. Third edition. Pp. 230 — 4 X 6>4 ; 7s. 

 6d. net. W. Heffer & Sons, Ltd., Cambridge, Eng., 1913. . 



Very useful laboratory manual. Subject treated chiefiy from static point 

 of view. Practical throughout. Methods well selected. Quantitative pro- 

 cedures given satisfactory attention. Special emphasis laid upon Folin's micro- 

 chemical methods of urinary analysis. Good index. See review by Walter 

 Jones, Jour. Anier. Chem. Soc, 1913, xxxv, p. 1064. Gies. 



Physiological Researches. (Appears at irregulär intervals.) Edited by 

 Burton E. Livingston (Manager), Johns Hopkins Univ.; Daniel T. MacDougal, 

 Carnegie Inst, of Wash. ; and Herbert M. Richards, Columbia Univ. Vol. I: 

 No. I — The rclation of environmental conditions to the phenomenoii of perma- 

 nent wilting in plants, by Joseph S. Caldwell. Pp. 1-56 — 4% X 75^ ; July, 1913; 

 $0.75 ($5.00 per vol.). Physiological Researches, Station N, Baltimore, Md. 



Physiological Researches, unlike the conventional Journal, appears at 

 irregulär intervals in the form of individual physiological papers, paged 

 sequentially ; each succession of about 450 pages will be a volume unit. The 

 papers will be numbered sequentially, in each volume and in the whole series. 

 An editorial feature will be the publication of an author's abstract in advance 

 of the appearance of each paper, and also as a preliminary part of each paper 

 in its final form in the series. Although the three editors are eminent botanists, 

 it is their intention to make Physiological Researches, as its name implics, an 

 archive for physiology in its broadest and deepest scnsc. This new publication 

 bcgins its career auspiciously and promises not only to rival the Ainer. Jour. 

 Physiol. in interest and value, but also to sharc with that Journal the high credit 

 of stimulating the advancement of physiological research. The initial paper, by 

 Prof. Caldwell, is a masterly treatment of an interesting and perplexing subject, 

 and establishes a Standard of merit which will doubtless characterize each issue 

 of PJiysioIogical T<esearches. Gies. 



Researches in biochemistry conducted in the Johnston Laboratory, 

 Univ. of Liverpool. Edited by Benjamin Moore, Johnston prof. of biochem..
