carried on, under the auspices of the Earthquake Investigation 

 Committee, during the four summers from 1893 to 1896. The 

 Appendix gives a complete list of the observations, reduced to 

 18950 and sea-level. A large number of plates and eleven 

 beautifully executed maps accompany the text. Many of the 

 maps are double, a thin rice-paper chart covering a second one 

 on thick paper; in this way a double series of data are presented. 



6. Beitrage zur chemischen Physiologie, herausgegeben von F. 

 Hoemeister. Band VI. 1905. Braunschweig (F. Vieweg und 

 Sohn). — The present volume, like its predecessors, contributes a 

 large number of new data to the literature of physiological chem- 

 istry. Only a few of the 41 papers can be selected for special 

 mention in this place. Many of them deal with the chemistry of 

 metabolism. Thus von Bergmann and Langstein have investi- 

 gated the "residual nitrogen" of the blood; Knop, the meta- 

 bolism of aromatic fatty acids ; Eppinger, the physiological 

 formation of allantoin and urea ; Blum en thai, the assimilation 

 limits for common sugars after intravenous introduction ; and 

 Steinitz and Weigert, the composition of the body after improper 

 nutrition. Dr. von Furth has published the details of an 

 extensive study of the oxidative decomposition of proteids. 

 Friedmann's research on the chemical structure of adrenalin, 

 Pollak's paper on the diversity of trypsins, and Embden's various 

 papers on carbohydrate metabolism indicate the scope of the 

 journal. Students of haemolysis and related topics will be inter- 

 ested in the papers by Pascucci upon the chemistry of the stroma 

 of the red blood corpuscles, and one by Hausmann on the 

 behavior of saponin in the presence of cholesterin. l. b. m. 



7. Du Baboratoire d V " Tlsine • par Louis Houllevigue, Pro- 

 fesseur a l'Universite de Caen, 299 pp., 12rao. Paris, 1904 (Ar- 

 mand Colin). — This useful little book discusses in elementary 

 form a wide range of well-selected practical topics : the part 

 played by machines ; the gas meter; the transformation and dis- 

 tribution of energy ; the industrial Alps ; electro-chemistry : 

 lighting by incandescence ; the production and use of extreme 

 cold ; molecules, ions and corpuscles. The method of presenta- 

 tion is adapted to the requirements of the ordinary public inter- 

 ested in the applications of science. 



8. Traite Gomplet de la Fabrication des Bieres ; par MM. G. 

 Mokeau and Lucien Levy. 674 pp., 5 plates, 173 figures in the 

 text. Paris, 1905 (Libr. Poly technique, Ch. Beranger Editeur, 

 successeur de Baudry et Cie.).— This volume, like others which 

 have preceded it from the same publishers and belonging to this 

 series, is a very complete and exhaustive discussion of the subject 

 of which it treats. This is somewhat out of the range of this 

 Journal, but attention may be called to the discussion of the 

 botanical side of the various forms of hops and barley, also of 

 the yeast, and of the part played by bacteria ; these have more 

 than a technical interest. The illustrations are numerous and 

 good and the whole presentation of the technical part of the sub- 

 ject is very thorough.
