Das Sauerstoff Bedurfniss des Organismus. Eine farben- 



analytische Studie von Professor Dr. P. Ehrlich. pp. 167. (Berlin : August. 

 Hirschwald. 1885.) 



The author asserts "that it may be positively laid down that the living 

 tissue, through its cells, draws and stores up the oxygen of the blood with a 

 certain force, in order to use it up according to laws as yet unknown. This 

 need of oxygen may be in general explained by the fact that the living proto- 

 plasm is enabled to enter into a chemical union with the oxygen, which must 

 differ in kind according to the nature of the organs." 



Lehrbuch der Geophysik und Physikalischen Geogra- 



PHIE. Von Dr. Siegmund Giinther. In 2 vols. (Stuttgart : Ferdinand 

 Enke. 1884—5.) 



Dr. Giinther, who is an able physicist, has given us two very fine volumes, 

 the first of which treats of terrestrial physics under such heads as the Relations 

 of the Earth to the other Planets, the Form of the Earth, the Effect of its 

 Motion, and the Condition of its Interior ; these are followed by a discussion 

 of volcanoes and earthquakes. The second, and by far the larger, volume 

 treats of Magnetism and Electricity, the Atmosphere, Oceanography and 

 Physics of the Ocean, Geology, etc. We should much like to see an English 

 edition of this work. 



The Theistic Conception of the World : An Essay ia 



Opposition to Certain Tendencies of Modern Thought. By B. F. Cocker, 

 D.D., LL. D. pp. vii. — 426. (New York : Harper Bros.) 



A closely-argued and well-written book. The learned professor attacks the 

 tendency of the present day to remove the Divine Being from any care or 

 control over His works. Chapters viii., ix., and x. are specially interesting, 

 and, as we think, completely successful in their reasonings and true in their 

 conclusions. 



The Origin of the World, according to Revelation and 

 Science. By J. W. Dawson, C.M.G., LL.D., F.R.S. Third edition, pp. 438. 

 (London: Hodder and Stoughton. 18S4. ) Price 7s. 6d. 



The intention of the author is, as he tells us, to throw as much light as 

 possible on the present condition of the much-agitated questions respecting the 

 origin of the world and its inhabitants. We scarcely think he has succeeded 

 in his Ijold attempt of reconciling the present state of cosmic knowledge with 

 revelation. There are several chapters of much interest, and particularly so 

 are the appendices to the work. 



The Elements of Moral Science : Theoretical and Practi- 

 cal. By Noah Porter, D.D., LL.D., President of Vale College. Pp. xxv.— 

 574. (London: Sampson Low, Marston, and Co. 1885.) Price los. 6d. 



We very heartily commend the book to our readers. It is most careful and 

 practical, and touches upon all the relations of man to the Almighty, to himself, 

 and to the world around. It is difficult to point out any one special subject as 

 most worthy of reading and attention amidst such a mass of matter, but we 

 were much struck with chapters iv. and v. in Part I. on the Will of Man, and 

 to certain chapters in Part II. on Man's Duties towards himself and society 

 and towards animals. It is most healthy reading, and will well repay study.
