It was in 1863 that Dr. Atkinson first put 

 before English readers his excellent translation 

 of Ganot's 'Elements de Physique,' a book 

 which quickly won favor by its good arrange- 

 ment and lucidity. In the first edition he 

 graciously apologized for the use of the metric 

 system. It has passed through fifteen or more 

 editions since its introduction. A demand soon 

 arose for the more elementary course by the 

 same French author, as a text-book for the 

 middle and upper classes of schools preparatory 

 to college. The popularity of this is mani- 

 fested by the appearance now of its ninth edi- 

 tion, a considerable part of which had been 

 prepared for the press before the death of Dr. 

 Atkinson. The present volume has all the ex- 

 cellences of its predecessors, the illustrations 

 being abvxndant, and some of them possibly a 

 trifle too expensive. Colored lithographs of 

 metallic spectra and of Geissler tube discharges 

 were formerly fashionable, but in a general 

 treatise to-day they seem almost out of date. 

 For the general reader it would be hard to find 

 a more pleasant and satisfactory book than this 

 volume. For American school purposes, how- 

 ever, it is too diffuse ; and it seems adapted 

 only for recitational purposes where oral an- 

 swers are given to questions relating to descrip- 

 tive details and general principles. Physics is 

 nothing if not a quantitative science. This 

 idea is best instilled into the elementary stu- 

 dent, even though his mathematical attainments 

 be not sufficient to warrant the use of complex 

 problems. 



The present volume illustrates the difficulty 

 of maintaining a text-book up to date by slight 

 modifications and additions applied in succes- 

 sion to a long series of new editions. As years 

 pass on, the necessity for omissions becomes as
