GEOLOGY: 



INTRODUCTORY, DESCRIPTIVE, AND PRACTICAL. 

 BY PROFESSOR ANSTED. 



" It is a companion for the study and the field, and contains an excel- 

 lent exposition of practical Geology, entering on a clear and full review of 

 the applications of the science to mining and the attendant operations, to 

 the hygiene of mines and especially coal-pits, to engineering and architec- 

 ture, and to agriculture." Athenaeum. 



" He is an admirable writer, and has lucidly arranged in his volumes 

 the great facts and phenomena of Geology, without entering into absurd 

 and unsatisfactory speculations on their causes." Britannia. 



" Our own judgment of it has been formed upon a careful perusal of 

 nearly the whole treatise ; and knowing that it coincides with that of 

 many distinguished Geologists, we do not hesitate to express the belief 

 that it is better adapted to convey a competent knowledge of the certain- 

 ties of the science, than any other work with which we are acquainted." 

 British and Foreign Medical Review. 



" The important station which Professor Ansted occupies, and the 

 reputation he has obtained in fulfilling its duties, led us to expect a good 

 book at his hands ; but the work before us has exceeded our expectations, 

 being by far the best suited to the real wants of the age, of any work on 

 Geology that has yet appeared." Church of England Quarterly Review. 



<l It is comprehensive, yet concise ; clear, without being diffuse ; accu- 

 rate, without being tedious ; abounding in illustration, yet without de- 

 scending too far into minutiae ; it developes principles, and steers clear of 

 speculation." Civil Engineer and Architect's Journal. 



" Professor Ansted' s beautifully illustrated and interesting work 

 affords the best view of English Geology hitherto prodnced. On this 

 ground we recommend it to the particular attention of Geologists." 

 Jameson's Edinburgh New Philosophical Journal. 



"Herr Ansted schildert, in der erwahnten Reihenfolge, jede Felsarten- 

 Gruppe auf eine sehr gllickliche Weise ; ohne sich in peinliche Details 

 einzulassen, theilt er das Wichtigste mit." Leonard and Bronn's Jahr- 

 buch. 



" We look upon it as a first-rate production ; and we congratulate the 

 students of King's College on possessing such a guide as the author in 

 this important and seductive branch of human enquiry." Literary 

 Gazette. 



" Ansted's Geology is a very able work ; well arranged in its plan 

 comprehensive in its subjects, both principal and subordinate, and 

 scholarly in its treatment. The volumes are profusely illustrated, the 

 diagrams and the wood-cuts intermixed with the letter-press being highly 

 useful in explaining the text." Spectator, 



Over.
