REVIEWS. 201 



The Medical Annual and Practitioner's Index. A Yearly 



Record of useful information on subjects relating to the medical profession ; 

 pp. i6a — 371. (London : Henry Kimpton, 1885.) 



We find the second year's issue of this useful little annual much enlarged 

 and otherwise improved. The volume commences with a paper by Dr. J. E. 

 Taylor, Editor of "Science Gossip," entitled, "A Review of Popular and 

 General Science." We believe the chapters on Health Resorts have been in a 

 great measure re-written ; several new features are added to the book. 



World-Life, or Comparative Geology. By Alexander 



Winchell, LL.D. ; pp. XXIV., 642. (Chicago, U.S.A. : S. C. Griggs and 

 Co., 18S3.) 



The learned Professor in this exceedingly interesting book gives us a 

 thoughtful view of the processes of world-formation, world-growth, and world- 

 decadence. He has gathered together many of the important facts observed 

 in the constitution and course of nature, and has endeavoured to weave them 

 into a system by the connecting threads of scientific inference. 



Sparks from a Geologist's Hammer. By Alexander 



Winchell, LL.D. Second Edition ; pp. 400. (Chicago : S. G. Griggs & Co.) 

 This perhaps is a more popular work by the same author ; it consists of 

 descriptions, essays, and discussions of subjects suited to occupy the attention 

 of the Geologist. The subjects range from the descriptive and literary, to 

 scientific, historic, and philosophic. Thus we have the ^^isthetic, where the 

 reader is conducted on an interesting excursion to Mont Blanc ; the Chrono- 

 logical, in which is discussed the age of Continents, Obliterated Continents, 

 and a grasp of Geologic Time ; the Climatic, the Historic, and the 

 Philosophic. Readers will be charmed with this book. 



Geogony : Creation of the Continents by the Ocean Currents, 



an advanced system of Physical Geology and Geography. By J. Stanley 

 Grimes; pp. 116. (Philadelphia, U.S.A. : J. B. Lippencott and Co., 1885.) 

 The Author argues that "All the elevations of the earth's crust have 

 resulted from the sinking of the ocean basins, or of smaller local basins, 

 beneath the weight of the sediment. And that when the ocean covered the 

 globe there were three pairs of elliptical currents, which collected sediment on 

 the ocean's floor, the weight of which produced three pairs of sinking basins, 

 viz. — the North and South Atlantic, the Pacific, and the Indian Ocean basins. 



Paradise Found. The Cradle of the Human Race at the 



North Pole ; a Study of the Pre-Historic World. By William F. Warren, 

 S.T.D., LL.D., President of the Boston (U.S.A.) University; pp. XXIV.— 

 505, with original illustrations. (Boston : Houghton, Mifflen, and Co., 1885.) 

 To many of our readers it will appear a startling assertion that the Cradle 

 of the Human Race was situated at the North Pole. Dr. Warren assures us, 

 however, that such is the fact, and in the book before us he gives us the 

 arguments by which his theory of Polar origin is very carefully worked out. The 

 work is divided into six parts. In the first we have a survey of the present 

 state of the question, giving the results of explorers, both historic and legend- 

 ary, followed in Part II. by his own hypothesis. In Part III. this is
