Becent work on protein hydrolysis, J. R. Green (8ci. Prog. Ticenlieth 

 Vent. 1 (1907), No. 3, pp. JiZl-Jf.'il). — A concise summary of investigations which 

 liave been reported in recent years regarding the cleavage and structure of 

 animal and vegetable proteids. 



A text-book of sanitary and applied chemistry or the chemistry of water, 

 air, and food, 10. IT. S. I'.ailev {Sew York and Loiidoii : The .\hiciiiilhni Co., 

 IDOIJ, pp. XXU-\-3Ji5). — The first part of this volume, which is designed as a 

 tcxt-boolc for class-room use, is devoted to water, air, heating, lighting, and 

 ventilation, and the second part to a discussion of food and beverages, including 

 food adulteration. Throughout the book experiments are outlined, and the 

 worlc as a whole constitutes a concise summary of data on the subjects treated. 



Practical guide for the detection of adulteration and sophistication of 

 food materials, I'. Breteau (Paris: -J. B. LiaUUere & Sons, 1907, pp. VIII 

 +386, pis. S, fujs. 1J,3; rev. in Jour. Pharm. et Cliim.. 6. ser., 25 (1907). 

 No. 2, pp. 89, 90). — This volume is designed as a handbook for students, and 

 contains descriptions of apparatus, chemical methods, and directions for the 

 detection of tlie usual adulterants. The preface is by P. Cazeneuve. 



Agricultural chemistry in the first half of the year 1906, W. Zielstorff 

 (Cliein. Zisclir., (J907), No. 1, pp. 1-6). — A summary account is given of prog- 

 ress in cheniical investigations relating to plants and animal nutrition during 

 the period. 



Report of progress in inorganic chemical industry during the second and 

 third quarters of 1906, G. IIauter (Cheni. Ztschr., 6 (1907), No. 2, pp. 

 17-25). — The literature of investigation and invention in this field is briefly 

 reviewed. The investigations of special interest to agriculture noted in this 

 review are those relating to the preparation of ammonia and other nitrogen 

 compounds from waste in'oducts and from the nitrogen of the air. 



Extracts from the proceedings of the association of official agricultural 

 chemists, 1906 (U. 8. Ik^pt. Agr., Bur. Chem. C'irc. 32, pp. l.'t). — This contains 

 the reports of the committees on recommendations of referees, with the action 

 taken by the association, the report of the committee on the revision of 

 methods, the resolution adopted concerning the next place of meeting, and a 

 list of the oflicers, referees, and committees for the year 1907. (See also E. S.

 fourth annual issue of this catalogue, previous issues of which have already 

 been noted (E. S. R., 16, p. 74.5). Part 1 is arranged by authors and part 2 by

METEOROLOGY— WATER. 



Some world's weather problems, W. J. S. Lockyer (8ci. Prog. Tu'entieth 

 Cent., 1 (1906), No. 2, pp. 206-221, figs. 2).— The great advances in meteorology 

 made possible by improved means of exploring the upper air are referred to and 

 the fundamental relations between barometric pressure and weather changes are 

 discussed with esi)ecial reference to the barometric see-saw between nearly 

 antipodal i)arts of the earth, which has been worked out by the author and Sir 

 Norman Lockyer. 



A map illustrating this phenomenon is given, and the general inverse relation 

 between rainfall and pressure in India, Australia, and England duriqg the 

 period from 1870 to 1900 is also charted. 



The general conclusions from these investigations on pressure observations 

 are (1) that all over the world changes of long duration are in operation, and
