For the proportion of land and water on the globe, Rigaud deduced the 

 ratio 100 : 270, and Humboldt, the ration 100 : 280 ; and this corres- 

 ponds with 3 2 : 5 2 which equals 9 : 25 or 100 : 277. The land of the 

 American continents equals 10,606,400 sq. m., and that of the other hem- 

 isphere, 27,274,000 sq. m.; the ratio is 1:2-57 which equals 5 2 :8 2 . 

 These are a few examples from the work. 



16. Principles of Chemistry, embracing the most recent discoveries in 

 the Science, and the outlines of its application to Agriculture and the Arts. 

 Illustrated by numerous experiments newly adapted to the simplest appa- 

 ratus ; by John A. Porter, M. A., M.D., Prof. Agric. and Organic Chem. 

 in Yale College. 480 pp. 12mo. New York, 1856. A. S. Barnes & Co. 

 — In the preparation of this text-book, Prof. Porter has aimed at a clear, 

 simple and practical presentation of the principles of Chemistry, not over- 

 loaded with details, and with such experimental illustrations as may be 

 repeated with simple means, small expense, and little previous knowledge. 

 The plan is well carried out, and the work is an excellent one for classes 

 in Chemistry.
