3. The Age of the Killarney Granite; by W. H. Collins. 

 Geol. Surv.,' Canada, Museum Bull. No.. 22, 1916, 12 pp., l pi., 

 1 text fig. — This interesting pamphlet shows that the Huronian 

 sediments on the north shore of Lake Huron, of more than 12,000 

 feet thickness, are intruded by sills and dikes of diabase that are 

 probably of Keweenawan age. Near Thessalon they are overlain 

 by a basic volcanic flow. Finally, and most important, they are 

 also intruded by granite masses of a bathylithic nature that are 

 of later pre-Cambrian age. These intrusions have folded and 

 faulted the sedimentaries along the north shore of Lake Huron to 

 a degree far more intense than elsewhere in Ontario. " The axis 

 of folding crosses the district in a wide, southward curved arc." 

 These bathylithic mountains of Proterozoic time were widely over- 

 flowed by tbe earty Paleozoic seas and the region remained dias- 

 trophically neutral until Pleistocene time, when it was re-elevated 

 to its present altitude. c. s. 



4. Morphology and Anthropology, a .Handbook for Students ; 

 by W. L. H. Duckworth. Second edition, Volume I, pp. xvi, 

 304; 208 text figures. New York, 1915 (Cambridge Univ. 

 Press ; G. P. Putnam's Sons). — The second edition of this excellent 

 handbook for students of the morphological aspects of anthro- 

 pology has been entirely rewritten and is more abundantly illus- 

 trated than the first edition of 1904. It is a careful study of the 

 general anatomy of the primates, the ancestors of man. About 

 50 pages are devoted to setting forth the classifications of the 

 mammals, and 150 pages to the general anatomy of the primates. 

 One chapter deals with the crania, another gives in much detail 

 the dental system of the primates, the theories of cusp- 

 development and the origin and fate of cusps. c. s.
