 1702, Glaris shaken throughout. In 1703, Nov. 26. occurred the 

 famous great storm. (Bertrand, p. 85.)

 carts passed over. Vines and olive trees frozen through. (M. 

 xii. 61.) Vesuvius was in agitation from 1704, more or less during 

 the whole period, till 1737. (Auldjo and Daubeny.) From 1707 to 

 1709, Little Kameni was being formed. {Lyell, i. 386.) 1706, 

 May 5. Teneriffe was shaken. 1707, Santorini was in eruption; 

 on Jan. 24. (Feb. 18. O. S.) there was an aurora at Copenhagen ; 

 on Nov. 10. an aurora in Ireland. 1708, July 31. a meteor seen 

 all over England (P. T.) ; and on Aug. 9. and 10. 1708, an 

 aurora at London. On May 18. 1710, there was an extraordinary 

 meteor in Yorkshire. (P. T.) 



There were meteors also on March 19. 1718 — 1719; 

 and all over Germany, on Nov. 7. 1623; in 1718, there 

 were earthquakes in Switzerland, from July to December ; 

 and on March 6, 7. a violent earthquake at St. Vincent's ; 

 Vesuvius being in eruption (from June 6. 1717 till) 1718. 

 El Pico was in eruption also this year ; and on June 3. an ex- 

 traordinary water-spout fell in Lancashire. In 1623, there 

 were earthquakes all over Switzerland, and through Ger- 

 many to Holland. The following coincidences may be also 

 marked : —

 rains ; 1380, by storms ; 1470, by snow and excessive cold ; 1533, 

 by storms ; 1576, by great cold ; 1584, by rains and thunder, and 

 hail of stones and earth ; 1601, by great rain and floods, and 

 the drying up of rivers ; 1607, on April 2., in the Pays de Vaud, 

 followed immediately by storms; 1619, by violent winds and

 10., at Berne, preceded, Sept. 9., by a violent hurricane; 1652, 

 preceded by fiery meteors in 1651 ; 1654, by storms. 



I trust these instances will be sufficient to furnish proof that 

 I have not advanced my position without ground to rest it on. 

 The desire to establish it, as strongly as possible, has led me 

 into a longer discussion than I had intended : but it is to be 

 remarked, that, if Professor Olmsted's comet have any actual 

 existence, some of my ideas are untenable ; and that must 

 plead an apology with the readers and correspondents of the 

 Magazine of Natural History.
