PHYSICAL GEOGRAPHY. 



BY MARY SOMERVILLE. 



A NEW AMERICAN FROM THE LAST AND REVISED LONDON EDITION. 

 AVITH AMERICAN NOTES, GLOSSARY, ETC. 



BY W. S. W. RUSCHENBERGER, M. D., U. S. N. 



In one neat royal 12mo. volume, extra cloth, of over five hundred and fifty pages. 



The great success of this work, and its introduction into many of our higher schools 

 and academies, have induced the publishers to prepare a new and much improved 

 edition. In addition to the corrections and improvements of the author bestowed on 

 the work in its passage through the press a second time in London, notes have been 

 introduced to adapt it more fully to the physical geography of this country ; and a 

 comprehensive glossary has been added, rendering the volume more particularly suited 

 to educational purposes. 



Our praise comes lagging in the rear, and is wellnigh superfluous. But we are 

 anxious to recommend to our youth the enlarged method of studying geography which 

 her present work demonstrates to be as captivating as it is instructive. We hold 

 such presents as Mrs. Somerviile has bestowed upon the public, to be of incalculable 

 value, disseminating more sound information than all the literary and scientific insti- 

 tutions will accomplish in a whole cycle of their Qx\%\.ence.—BlacktDood's Magazine. 

 From Lieutenant Maury ^ JJ. S. N. 



National Observatory, Washington, June 26, 1853. 



I thank you for the " Physical Geography;" it is capital. I have been reading it, and 

 like it so much that I have made it a school-book for my children, whom I am leaching. 

 There is^ in my opinion, no work upon that interesting subject on which it treats— Physical 

 Geography— that would make a better text-book in our schools and colleges. I hope it 

 will be adopted as such generally, for youhave Americanized it and improved it in other 

 respects. Yours, truly, 



M. F. MAURY.

 I hold it in the highest estimation, and am confident that it will prove a very efficient 

 aid in the education of the young, and a source of much interest and instruction to the 

 adult reader. 



From Erasttis Everett, High School, New Orleans. 

 I have examined it with a good deal of care, and am glad to find that it supplies an im- 

 portant desideratum. The whole work is a masterpiece. Whether we examine the 

 importance of the suljjects treated, or the elegant and attractive style in which they are 

 presented, this work leaves nothing to desire. I have introduced it into my school for 

 the use of an advanced class in geography, and they are greatly interested in it. I have 

 no doubt that it will be used in most of our higher seminaries. 



JOHNSTON'S PHYSIC AI, ATLAS. 



THE PHYSICAL ATLAS 



OF NATURAL PHENOMENA. 



FOR 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 and strongly bound. With 



twenty-six plates, engraved and colored in the best style. Together 



with one hundred and twelve pages of Descriptive Letter-press, 



and a very copious Index. 



A work which should be in every family and every school-room, for consultation and 

 reference. By the ingenious arrangement adopted by the author, it makes clear to the 

 eye every fact and observation relative to the present condition of the earth, arranged 

 under the departnnents of Geology, Hydrography, Meteorology, and Natural History. 

 The letter-press illustrates this with a body of important information, nowhere else to 

 be found condensed into the same space, while a very full Index renders the whole 

 easy of reference.
