 duction to the Study of Physical Phenomena. By Amedee 

 Guillemin. Translated from the French by Mrs. Norman 

 LoCKYER ; and Edited, with Additions and Notes, by J. Norman 

 LOCKYER, F.R.S. Illustrated by Coloured Plates, and 455 Wood- 

 cuts. Third and cheaper Edition. Royal Svo. 21s. 

 " Translator and Editor have done justice to their trust. The 

 text has all the force and ftoxv of original writing, combining 

 faithfidness to the author s jneaning with purity and independence 

 in regard to idiom; while the historical precision and accuracy 

 pei-vading the work throughout, speak of the watchful editorial 

 supervision which has been given to ruery scientific detail. Nothing 

 can well exceed the clearness and delicacy 0/ the illustrative wood- 

 cuts. Altogether, the work may be said to have no parallel, either 

 in point oj fulness or attraction, as a popular manual of physical 

 science. .... What 'Me feel, however, bound to say, and 

 what we say with pleasure, is, that among works of its class no 

 publication can stand comparison either in literary completeness or 

 in artistic grace with it." — Saturday Review.
