 has made copious additions, including chapters on Chemical Manipulations, 

 Organic Analysis (including Alcohol, the Sugars, Starches, Alkaloids, Albu-

We have here a popular and very readable account of facts known about 

 the moon, in which ancient and modern theories are placed side by side. 

 Those who wish to know something about our satellite without dipping too 

 deeply into science will do well to read this little work. 



The Ordnance Survey of the United Kingdom. By 



Lieut. -Col. T. Pilkington White, R.E. Crown Svo, pp. x.-— 174. (Edin- 

 burgh and London : \V. Blackwood and Sons. 1886.) 



Gives in a popular and interesting manner a very intelligible idea of the 

 great national survey : what it is, how and when it originated, what are its 

 objects, by whom and in what manner it is executed, and who pays for it. 

 The system of triangulation is carefully explained, and all the methods adopted 

 are put before the reader in a very attractive manner. 



Solar Heat, Gravitation, and Sun-Spots. By J. H. 



Kidzie. Crown Svo, pp. xii. — -304. (Chicago: S. C. Griggs and Co. 18S6. 

 Price, $1.50.) 



We have in this volume a new and striking theory with respect to the phe- 

 nomena of Solar Heat, Gravitation, and Sun-Spots. The author's views are 

 unquestionably his own. On the subject of Solar tleat he tells us that, as 

 there are not less than five or six different theories already advanced by emi- 

 nent scientists, a new theory cannot therefore be considered as conflicting with 

 any settled doctrine on the subject, and that with regard to the cajise either of 

 gravitation or sun-spots the field is still more completely unoccupied. The 

 work contains upwards of 20 good illustrations.
