VOLCANOES: VISIT TO HAWAII, l88/ 



Origin of the Volume on Volcanoes Revisiting Hawaii Changes since

 tramp after minerals on the solfataric island of Milo. 

 They were continued in 1838 by short excursions on

 by explorations of the active and extinct volcanoes of the 

 Hawaiian Islands; in 1841, by observations on a crater in 

 the coast region of Oregon, instructive though distant

 and a brief survey of an extinct volcano on the Sacra-
