" Its disadvantages are of a theoretical nature, and consist in the presumed 

 destruction of the antiscorbutic properties of fresh millv. This, however, can 

 be compensated, if thought necessary, by administration of fruit juice. For 

 domestic purposes apart from infant feeding, dried millc has distinct limitations 

 as a substitute for fresli millv. as. owing to its taste, it is not so suitable for add- 

 ing to tea or coffee." 



The laws of digestion and resorption, S. Arrhenius (Ztschr. riii/.siol. Chcm., 

 63 (WOO), \o. .5. pp. 323-317, dgms. 3; Meddcl. K. Yctensk. Akad. Nobelinst., 

 1 (1909), \(). I.'i, pp. 31, dgm. I). — This matliematical discussion of the laws of 

 digestion is based on the studies of digestion which have been reported by E. S. 

 London. 



Handbook of physiological methods — respiration and digestion, edited by 

 K. Tigersti:dt { Hundhuch dcr phij.siolof/ischcn Mcthodik — AiiHiiiiff-^'crdaiiung. 

 Lcipsic, 1908, vol. 2, pi. 2, pp. 18H, flg.s. 3(>). — Tliis volume contains four papers, 

 namely, Respiratory Movements, by F. Sclienk ; Methods of Studying p]nzymic 

 Reaction, by ('. Oppenlieimer; Movements of the Digestive Tract, by R. Magnus; 

 and Operative Methods for the Study of the Digestive Glands, by I. P. Pawlow. 



Bibliographies are provided and the volume as a whole, like the others in the 

 same series, is designed as a handbook for laboratory use. 



Handbook of physiolog'ical methods — muscle physiology, edited by R. 

 TiGERSTEDT { Jldiidhiich dcK phg.siologi.sitioi Mcthodik — M iiskclpligsiologic. Lcip- 

 sic, 190H, vol. 2, pt. 3, pp. .'iS8, pis. 11, figs. 179). — This volume contains four 

 papers, namely. Methods for Studying the Thermodynamics of Muscles, by K. 

 Biirker; Muscle Mechanics in (Jeneral, by M. von Frey; Methods for Studying 

 Special Forms of Muscular Movement, by O. Fischer; and Electro-Physiology, 

 by S. Garten. 



Bibliographies are provided, and, as with other volumes of the series, the sec- 

 tions constitute digests of available information on the subjects considered, 

 with special reference to students' needs. 



Treatise on physiology — heat, O. D. Chwolson (Trnifr dc Physique — 

 VKncrgic ('alorifiquc. Paris. 1909, vol. 3, pt. 1, pp. 17/ + '/08, figs. /26).— In this 

 exhaustive study of the question of heat from the standpoint of body energetics 

 the author discusses thermochemistry, the variations in the size and pressure 

 of bodies as a function of temperature, the heat capacity, the transformation 

 of forms of energy into heat, thermochemical phenomena, cooling of bodies, and 

 heat conductivity. 



The different sections are provided with bibliographies and the volume as a 

 whole is a liand]>ook on thernioclieniistry and related topics. 



Concerning the problem of protein metabolism, K. Rothenstein (Beitrag 

 zum ProWcm dcs Eiwciss-Stoffwechsels. Inaug. Diss., Univ. Bern, 1909, pp. 

 19). — Experiments are reported on the income and outgo of nitrogen, dogs 

 being used as subjects. 



The utilization of proteid cleavage products in the animal body. XI, 

 Experiments with man, E. AlBderhalden, F. Frank, and A. Schittenhelm 

 (Ztschr. Phiisiol. Chcm., 63 (1909), \o. 2-3, pp. 215-221).— According to the 

 experimental data reported, the authors were able not only to prevent the loss 

 of nitrogen but also to induce nitrogen gains in a 1.5-day period in which the 

 final cleavage products of meat were given very largely per rectum. 



The cleavage of nucleic acid taken in the food in the case of normal man, 

 F. Frank and A. Schittenhelm (Ztschr. Physiol. Chein., 6'3 (1909), No. 4, PP- 

 269-282). — From their investigations the authors conclude that it is not neces- 

 sary to prolong an experiment more than a day after the close of the feeding
