THE PHYSICAL ATLAS 



OF NATURAL PHENOMENA. 



FOK THE USE OF COLLEGES, ACADEMIES, AND FAMILIES. 



BY ALEXANDER KEITH JOHNSTON, F.R. G.S., F. G. S. 



In one large volume, imperial quarto, handsomely bound, 



With Twenty-six Plates, Engraved and Colored in the hest style. 



Together with 112 pages of Descriptive Letter-press, and a very copious Index. 



This splendid volume will fill a void long felt in this country, where no 

 work has been attainable presenting the results of the important science of 

 Physical Geography in a distinct and tangible form. The list of plates sub- 

 joined will show both the design of the work and the manner in which its 

 carrying out has been attempted. The reputation of the author, and the 

 universal approbation with which his Atlas has been received, are suflicient 

 guarantees that no care has been spared to render the book complete and 

 trustworthy. The engraving, printing, and coloring will all be found of the 

 best and most accurate description. 



As but a small edition has been prepared, the publishers request all who 

 may desire to procure copies of the work to send orders through their book- 

 sellers without delay.

The intention of this work is to exhibit, in a popular and attractive form, 

 the results of the researches of naturalists and philosophers in all the more 

 important branches of Natural Science. Its study requires no previous train- 

 ing ; for while facts and deductions are stated according to the strictest rules 

 of scientific inquiry, they are by an ingenious application of colors, signs, 

 and diagrams, communicated in a manner so simple and striking as to render 

 them at once intelligible and easily retained. 



For the first time, in this country, the principles of graphic representation 

 are here applied to the delineation of the most itnportant facts of external 

 phenomena. Simple but significant symbolical signs have been introduced
