the effect produced.* Yet a certain apparent influence of 

 earthquakes, in cases where they occupy much space in 

 changing the commencement of the rainy season, as in the 

 highland of Quito and Riobamba (in February, 1797), or in 

 the south-eastern countries of Europe and Asia Minor (in the 

 Autumn of 1856), might indeed be viewed as the isolated 

 influence of a volcanic eruption. 



In the following table the first figures denote the number 

 of the volcanoes cited in the preceding pages, while the second 

 figures, inclosed in parentheses, denote the number of those 

 which in recent times have given evidence of their igneous 

 activity.

 before the great earthquake which destroyed Lisbon. It appeared to 

 be composed of earthy particles reduced to an extreme degree of fine-

 called the " Little Antilles," three or four still active volcanoes having
