ment of that race-tendency which seeks in , 

 nature for the proof of the existence of 1 

 God. In Nature, paganism found at first 

 many gods ; and our present monotheistic 

 idea (outside of Christianity) seems to be 

 the result of the gradual extinction of the 

 belief in diverse deities, by the process of 

 discovering a sinzle force moving the uni- 

 verse of matter." 



A>* ELEMENTARY TREATISE ON ELECTRICITY. 



By James Clerk Maxwell. Edited by 

 William Garnet t. Oxford : Clarendon 

 Press. 1881. Pp. 208. Price, $1.90. 



The greater part of this work consists 

 of articles written by the late Professor 

 Maxwell some years before his death, with 

 a view to their ultimate publication as an 

 elementary text-book of the subject. Owing 

 to the labor involved in the editing of the 

 Cavendish papers, they were left in a very 

 incomplete state at the time of his death, 

 but the editor has endeavored to carry out 

 the original purpose, by supplementing them 

 with material taken from Professor Max- 

 well's larger work, "Electricity and Mag- 

 netism." The first two chapters are de- 

 voted to an experimental demonstration of 

 the principal facts relating to electric charge 

 considered as a quantity capable of in- 

 urement, and the third to electric work and 

 energy. In the fourth chapter the electric 

 field is considered, and Faraday's law of 

 lines of induction forms the subject of the 

 fifth. Some particular cases of electrifica- 

 tion are taken up in the sixth chapter, elec- 

 trical images in the seventh, and conden- 

 in the eighth. The various phenomena of 

 the current form the subject of the ninth 

 and tenth chapters, while the methods of 

 maintaining it are considered in the eleventh. 

 The twelfth chapter is devoted to the meas- 

 urement of electrical resistance, and the 

 thirteenth and last to electrical resistance of

The Mother's Guide in the Management 

 and Feeding of Infants. By John M. 

 Keating, M. D. Philadelphia : Henry

 tl. 



The author has endeavored to supply a 



want which he believes to be daily growing, 



as the monthly nurses of the last generation, 



whose knowledge gained by experience gave

them a place hardly secondary to that of the 

 doctor, are passing away the want of a 

 better understanding of the requirements 

 of a new-born babe. A n>: for arti- 



ficial feeding has been developed; over- 

 luxurious and overheated dwellings have 

 raised the question of proper clothing ; and 

 the rapid advancement of science has taught 

 us the value of early treatment to eradicate 

 the tendency to inherited taint. For ex- 

 plaining these matters, the work considers 

 the requirements of the infant, first from 

 birth till the catting of its first teeth, then 

 during the period of dentition, and finally 

 those of a child after its third vear. 



Opium-Smoking in America and China. A 

 idy of its Prevalence and Effects, Im-

 icans is made manifest by the fact that the 

 practice, comparatively unknown among us

 the "West and large cities in the East abo\: 

 in places where this drug is sold 



; and that in some of E bates it 

 has been found necc - j to enact repn 

 ive laws on the subject. Dr. Kane I 

 made careful investigations of the methods 

 and effects of opium-smoking, by personal 

 experiment, by the observation of smok 

 in the act and afterward, by correspond- 

 ence and communication with other similar 

 observers, and by the consultation of books 

 in which the subject is discussed, and c:
