Mr. T. Dobson on the Theory of Cyclones, Waterspouts, tyc. 441 



" 1348. Cyprus. An earthquake and a frightful hurricane." 

 — Hecker. 



"1819. Bagdad. An earthquake and a storm, an event quite 

 unprecedented. 



u 1820, Dec. Zante. Great earthquake and hurricane, with 

 manifestations of a submarine eruption." — Edinb, Phil. Journal. 



"1831, Dec. Navigators' Islands. Hurricane and earth- 

 quakes." — Williams's Missionary Enterprize. 



"1848, Oct., Nov. New Zealand. Succession of earthquake 

 shocks and several tempests. 



" 1836, Oct. At Valparaiso a destructive tempest and severe 

 earthquakes." — Naut. Mag. 1848. 



When an earthquake of excessive intensity occurs, as at Lisbon 

 in 1755, the volcanic craters, which act as the safety-valves of 

 the regions in which they are placed, are supposed to be sealed 

 up ; and it is a remarkable and highly suggestive fact, that no 

 hurricane follows such an earthquake. The number of instances 

 of the concurrence of ordinary earthquakes and hurricanes might 

 easily be increased, but the preceding suffice to show the gene- 

 rality of this coincidence both as to time and place. 



4. The breaking of waterspouts on mountains sometimes accom- 

 panies hurricanes. 



In 1766, during the great Martinique hurricane, before cited. 



" 1826, Nov. At Teneriffe, enormous and most destructive 

 waterspouts fell on the culminating tops of the mountains, and 

 a furious cyclone raged around the island. The same occurred 

 in 1812 and in 1837." — Espy and Grey's Western Australia* 



" 1829. Moray. Floods and earthquakes, preceded by water- 

 spouts and a tremendous storm." — Sir T. D. Lauder. 



" 1826, June. Hurricanes accompanied by waterspouts and 

 fall of avalanches in the White Mountains." — Silliman's Ame- 

 rican Journal, vol. xv. 



5. The fall of an avalanche sometimes produces a hurricane. 



" 1819, Dec. A part (360,000,000 cubic feet) of the glacier 

 fell from the Weisshorn (9000 feet). At the instant when the 

 snow and ice struck the inferior mass of the glacier, the pastor 

 of the village of Randa, the sacristan, and some other persons 

 observed a light. A frightful hurricane immediately succeeded." 

 —Edinb. Phil. Journ. 1820. 



6. Waterspouts occur frequently near active volcanos. 



This is well known with regard to the West Indies and the 

 Mediterranean. The following notices refer to the Malay Archi- 

 pelago and the Sandwich Islands : — 



"Waterspouts are often seen in the seas and straits adjacent
