prevalent Disorders, Sj-c, with Volcanic Emanations. 25 



Two or three other examples may suffice. On Oct. 24. 

 and 25. 1822, a most furious gale from the n.e., accompanied 

 by a fog, blew towards the shores of Durham and Northum- 

 berland. On the 24th, also, occurred a dreadful hurricane 

 at Genoa, attended with torrents of rain; which swelled the 

 rivers, and did incalculable damage. When the rain ceased 

 on the 25th, a lake was seen, with the tops of the houses and 

 trees only visible. (N. E. M., i. 470.) Now, on this day, 

 Vesuvius was in violent eruption : and it is scarcely possible 

 to separate that phenomenon from the hurricane at Genoa, 

 whatever may be said for the gale in England. 



The hurricane which occurred at Nevis on Aug. 17. 1827 

 (the severest for more than forty years) was preceded, a few 

 days before, by numerous shocks of earthquake ; seven and 

 nine being felt at a time in that island. Surely this is positive 

 proof. 



In the year 1827, there was, in Ireland, on Jan. 9-10. *, 

 and on the 16th also, a severe hurricane; the latter accom- 

 panied by hail, rain, westerly wind, and noises in the air 

 resembling explosions of artillery. (A. R.) From the 13th 

 to the 15th, also, there were tremendous gales off Holland. 



Now, on the 2d, a severe earthquake was felt in the depart- 

 ment of Orne, in France; and, on the 15th, there was an 

 earthquake at Hohen Memmingen, from n.w. to s.e. ; on the 

 29th, an earthquake at Ohnastetten ; and again, on Feb. 8., 

 from s.w. to n.e. .The two last set out from the Jura Alps, 

 ■where there are basalts. (Sckubler.) f On Feb. 10., there 

 was an earthquake in Caernarvon and Bangor, &c. ; and, on 

 the 23d, along the Rhine and in Belgium. (Schubler.) f On 

 the 17th occurred sudden and violent gales," rom the s.e., in 

 Scotland; while, on March 3. and 7., tremendous hurricanes, 

 with most extraordinary accumulations of snow, also did great 

 damage over the whole of Scotland. 



Since the preceding particulars were enumerated, accounts 

 have been published of a very sudden and frightful tornado 

 off the Island of Arran, on Sept. 4. 1834, which blew away 

 houses, and did incalculable damage. On the same day, at 

 8 a.m., an earthquake shook the mountains of Norway, and 

 was strongly felt at Christiania ; the distance of these localities 

 being scarcely 500 miles. Vesuvius was also still in eruption. 

 This case will, therefore, without difficulty, be allowed to bear 

 on my argument. 



Persons who have been frequently exposed to hurricanes, in 



* Avalanches were numerous in Switzerland on the 1 1th j and a dread- 

 ful snow storm occurred, the same day, in Yorkshire.
