The meteor seemed to deviate to the E. and to resume its 

 direction ; its height was about 50 miles : it was observed by 

 many persons that a whizzing was heard at the instant that 

 it passed. It moved at least 20 miles in a second : a velo- 

 city too great for a revolving body ; hence there is reason to 

 luppose its nature electrical. jMore than half the igneous 

 meteors .that have been observed, have moved nearly in the 

 direction of the magnetic.meridian. The author conjectures 

 thatW. Greenland, having become more icy in the course of 

 ye^rs, has had an eflcct on the distribution of the electric 

 fluid, and the electric fluid on the place of the magnetic 

 meridian.

Suspects that the fog of 1783 may possibly have been 

 produced by smoke " from the consumption by fire of some 

 of those great burning balls or globes vi-hich we happen to 

 meet with in our rapid course round the sun, and which ate 

 sometimes seen to kindle and be destroyed in passing our 

 atmosphere."

They were observed from a base of 46200 feet F. or 2.1 

 German geographical miles, 1 5 of which make a degree ; 

 their height was from 4 to 30 of those miles ; the mean 

 height about 11, or near 50 English miles. The velocity 

 of two of them was from 4 to miles, or about 22 English 

 miles in a second. One was brighter than Jupiter, and was 

 450 miles distant. 



In the second paper Dr. Benzenberg gives two instances 

 indctail. Scptem. 15. Ashooting starof the fifth magnitude. 

 Elevation of the beginning 7.7 geographical miles, of the 

 end 8.2. Length of the path 1.5 miles. Longitude of the 

 place of disappearance 28" 3' ; Latitude 53'' 22'. Observed 

 by Brandes, in Ekwarden, and Benzenberg, in Ham, near 

 Hamburg : length of the base 14 miles. October 3. An- 

 other of the fourth magnitude observed by the same persons. 

 The termination 7.1 geographical miles above the earth. 

 Ix)ngitude 27" "' ; Latitude 53° 5'. These observations 

 show, says Dr. Benzenberg, that a long base will furnish 

 as accurate a comparison as a shorter one ; that even me- 

 teors of the fourth and fifth magnitude may be seen at 

 places distant above fourteen geographical miles from each 

 other; and they confirm the former observations made at 

 Gottingen with a base of but one or two miles. Dr. Pott- 

 giesser, in Elberfeld, forty iniles distant from Hamburg, 

 saw a meteor on tiie 2nd of October, in the zenith, which 

 appears to have been the same as was scsn at Hamburg in 

 the horizon; its height is estimated at 25 German miles. It 

 was intended to continue these observations with unremit- 

 ting assiduity.
