Meteorological Observations. 399 



Daubeny on Active and Extinct Volcanos. 



Professor Daubeny of Oxford has in the press, and nearly ready 

 for publication, a new and much-enlarged edition of his Description 

 of Active and Extinct Volcanos. 



The present Edition will be found to contain nearly twice the 

 amount of matter included in the preceding one, embracing not only 

 such new facts and observations with respect to volcanos as have 

 been brought to light since its first appearance in 1826, but likewise 

 the allied phsenomena of Earthquakes and Thermal Springs, as well 

 as a fuller discussion of the theories connected with those subjects.
