preDalent Disorders, ^r., 'with Volcanic Emaiiations, 303 



for on Aug. 13. Vesuvius was in eruption ; SSd, there was an 

 earthquake at Hulst, and on the Axel in Holland ; 27th there 

 were earthquakes in Maryland, Virginia, doing great damage ; 

 and besides those in India on 29th, Jamaica was also shaken 

 at the end of the month. I shall adduce these hereafter, as 

 the cause of the dreadful hurricanes of August in general, 

 especially of that of August 30. and 31. Drought and the 

 cholera attended these earthquakes as they occurred. That 

 the air must have been exceedingly electrical at this time may 

 be inferred from a striking fact, that on September 1., in the 

 midst of a long and afterwards protracted drought at Antigua, 

 rain suddenly fell for twenty-four hours in that island ; and I 

 can only attribute it to the same cause which had produced 

 the hurricane of the two preceding days in Europe. 



On July 19. 1816, during the storms, inundations, and 

 hurricanes of that month and the next, there fell at Sternen- 

 berg, near Bonn, a number of aerolites, one of which weighed 

 100 lbs., others from 20 to 40 lbs. : their specific gravity was 

 that of marble, and their appearance was like iron scoriae. 

 The analysis I know not. On August 7. Vesuvius was in erup- 

 tion, and on the 13th all Scotland was shaken by earthquakes. 

 On February 1. and 2. there were earthquakes at Lisbon; on 

 March 27. the midland parts of England were shaken. On 

 September 24. there was a rare exhibition of the aurora in the 

 N. w., attended by an arch of light in the east. 



A singular circumstance occurred on October 20. 1824, 

 when hail, enclosing mineral stones {der mineralische kerne), 

 which Chladni took for sulphur, but which were discovered to 

 be a new meteorite, fell at Sterlitamanck, government of Oren- 

 burg, in Russia. (See Eversmann, in Kastner's ArcJiiv, v. 2. 

 196. ; Chladni, in Poggendorf'sAnnalen, vi. 1. 30. ; fully treated 

 of in Bulletin de la Societe des Naturalistes de Moscou for 1832, 

 V. 45.*) 



At the end of March, 1832 {Moscow Russian Gazette, April 

 11. 1832), there fell, with snow at the same time, in the plain 

 of Kirianova, 13 versts from Wolokolansk, an inflammable 

 yellowish matter like snow or wool, over an extent of 80 to 1 00 

 square rothen (600 or 700 feet), and from 1 in. to 2 in. deep.f 



fogs, the air is most electric. The air is, however, represented as par- 

 ticularly clear during the occurrence of various meteors alluded to in this 

 paper. 



* The same journal records that there was an earthquake at Symphero- 

 pol, on Jan. 17. (29.) 1832, at IIIa.m., also at Sevastopol (60 versts 

 off), which did great damage. Barometer fell all day. Thermometer, 3^^ 

 Reaumur; winds.w.; sky covered with light clouds. (Cons. Steven, in 

 Bulletin de MoscoUy iv. 207.) 



t On March 14. 1813, there fell in a heavy snow storm, at 4 p.m., a
