that he has propouuded in it new theories or original discoveries, but that the 

 book is a writing out of his own experience, without abridgment or re-writing 

 of other books. The result is admirable for perspicuity, for chann of exposi- 

 tion, and for solid instruction. The book is illustrated with twenty tinted litho- 

 graphs, from drawings by Mr. Jukes and Mr. Dunoyer, who is himself a Geologist, 

 and they are of rare excellence as illustrations ; altogether it is an introduction to 

 the study of Geology to be most emphatically recommended." — Leader. 



" This is one of the most remarkable works on Geology which have yet been 

 published ; Mi". Jukes has struck out a new path for the geological student, and 

 has done more to remove the diificulties which impeded his progress than any 

 previous author, llai'ely, indeed, have we perused any introductoiy manual with 

 greater pleasure; every word we have read has conveyed the impression that 

 Mr. Jukes is an original observer, thorouglily conversant with his subject, and 

 aware of the difficulties to be overcome. His language is graceful, simple, and 

 free from everything like scientific pedantry." — Liverpool Courier.

 piquant, as weU as forcible, so scholarly, yet so racy — his wit and his wisdom are 

 so skUfiilly blended — he has so cleverly worked out his motto, Ridentem dicere 

 verum, by telling the truth laughingly — that the reader finds liimself in'esistibly

 master of the talc that he has to unfold." — Leicestershire Mercury.

 illustrations too embellishing the volume." — Era.
