12. Outlines of Physiological Chemistry ; by S. P. Beebe and 

 B. H. Buxton. 195 pp. New York, 1904 (The Macmillan Co.). 

 — The title of this little book is perhaps somewhat misleading if 

 it gives the impression of any systematic review of the subject. 

 The aim of the authors is rather to deal with the theoretical side 

 of the various chemical questions arising in physiology, and to 

 explain the nature of the more important reactions with which 

 the student has to deal. The book includes chapters on the theory 

 of solutions, and on the chemistry of the carbon compounds ; the 

 more distinctly physiological part is almost entirely devoted to 

 the proteids and to enzyme action. The current theory of immu- 

 nity is also outlined. l. b. m.

1. Geological Survey of Canada, Robert Bell, Acting 

 Director. Annual Report, vol. xiii, 1900, 747 pp., 8 maps, 15 pis. 

 — The Canadian survey reports are always of interest because of 

 new territory explored and the geological reconnoissance which 

 is being carried on. The present report shows that a great 

 amount of work in several lines is being accomplished at small 

 expense. The principal papers bound in the volume are : Explo- 

 ration of East Coast of Hudson Bay and Geology of Nastapoka 

 Islands, by A. P. Low ; Parts of Saskatchewan, Athabaska, and 

 Keewatin, by J. B. Tyrrell, and also by D. B. Dowling ; Basin 

 of Nottaway River, by Robert Bell ; Geology and Petro- 

 graphy of Shefford Mountain, Quebec, by J. A. Dresser. These 

 papers have been previously issued separately. 



Dr. Low's investigations show that the land about Hudson 

 Bay is now 700 ft. above the level during the ice age. He finds 

 no evidence of present elevation. (For the contrary view see 

 article by Dr. Bell in Geol. Soc. Am., 1895.) The key to the 

 stratigraphic problems in the Cambrian, which shows buckling 

 and nearly horizontal movement, is found in the contraction of 

 intruded granite masses. " The contacts of the bedded rocks 

 and granites are usually unconformable and appear to be due to 

 a nearly horizontal movement of the bedded series subsequent to 

 the intrusions of the granite, due to pressure acting from outside 

 the great areas of granite. This series of sedimentary rocks 

 being close to the surface broke as does ice upon the shore when 

 pressed from seaward and piled cake on cake not only upon 

 unyielding granite but upon themselves." 



2. The Iowa Geological Survey, Samuel Calvin, State Geo- 

 logist : Vol. xiv, Annual Report of 1903, 655 pp., 38 pis., 132 fig.— 

 The last annual report of the Tow T a Geological Survey is chiefly 

 economic in character, and in addition to the annual statistics con- 

 tains an extensive treatment of clays and clay products in general 

 with special reference to the Iowa deposits. At the present time
