ETNA. 



A History of the Mountain and its Eruptions. 



Ey G. F. RODWELL, F.R.A.S., F.C.S. 

 With Maps and liiustraiions, 

 "Readers will be grateful to Mr. Rodwell for giving them very clearly, 

 and in a small compass, a great deal of information respecting this much- 

 observed volcano, which, without his aid, they would have no small difficulty 

 in obtaining."— ^rt/«r^(y Review. 



"In brief, Mr. Rodwell's * Etna * is a pleasantly- written and well-illus- 

 trated volume, sufficiently technical to be useful to the scientific student, yet 

 for the most part sufficiently popular to be read with relish by the most 

 unscientific. ' ' — A cademy.
