 abundant fall of rain." — Humboldt, Aspects of Nature. 



" 1843, Jan. Etna in eruption. Violent hurricanes at Genoa, 

 in the Bay of Biscay, and in Great Britain.

 volcanic eruption at Guadaloupe, followed by hurricanes in the

 in a typhoon." — Com. Hayes, R.N., in Naut. Mag. 1847.

 great volcanic eruption. On the 18th a gale of unusual violence

3. In volcanic regions, earthquakes and hurricanes often occur 

 almost simultaneously, but in no certain order, and without any 

 volcanic eruption being observed. 



In 1712, 1722, 1815 and 1851, earthquakes and hurricanes 

 occurred together at Jamaica. In 1762 at Carthagena ; in 1780 

 at Barbadoes; in 1811 at Charleston; in 1847 at Tobago; in 

 1837 and 1848 at Antigua; in 1819 an awful storm at Mon- 

 treal, rain of a dark inky colour, and a slight earthquake. People 

 conjectured that a volcano had broken out. In 1 766 the great 

 Martinique hurricane, a waterspout burst on Mount Pelee and 

 overwhelmed the place. Same night, an earthquake.
