^vi PREFACE, 



America ; the materials, if we may fo Ipeak, of thofe 

 fubterraneous fires, the accidents by which they are 

 kindled, and the confequenCes of their explofions : 

 the authors fentiments as to earthquakes, their ex- 

 tent and dire6lion, the circumftances preceding and 

 attending them, and their different efFedls in different, 

 places. 



The value of this Third Edition is very much en- 

 hanced, by a number of curious, inftrudlive, and ex- 

 planatory Notes. Thefe cannot fail of giving great 

 iatisfadlion to the reader, as they ferve to re6tify fome 

 miflakes, and to fet a variety of pafTages in a clearer 

 light, from the writer's thorough acquaintance with 

 the fubjed:s treated in thefe voyages. He has alfo 

 given a very accurate account of thofe parrs of Brazil 

 leaft known to us ; and which may be therefore fepa- 

 ratcd as a ufeful, as well as proper, fupplement ; and 

 render the work, taken altogether, as complete a§ 

 leven a critical reader can defire,
