nppffiiog ftem highly charged with electricity, on entering the sphere of the earth s 
dectiicitT, a discharge will take place, but without altering their existing motions. 
Tie observations of Braudes, Benzenburg and others, as is well known, 
wo^xi great heights to many meteors, varying from 6 to 500 miles. But M. 
^ shown {2nd Memoir, Acad. Bruxellc», vol. xv.) that the mean height J» 
MxxSeto to twenty leagues, nr loitkin the limits of the atmosphere. Hence the 
i^miTof them fflffy become luminous from comA«»fjoa. Klectric light can be dis- 
jMiiram. Hence we may have various gradations of the same phiBnomenon 
~-pEely electric flashes or explusiuan at great altitudes to more or less complete 
wwition at lower, by which the whole dims may be co«j»«wed and dUtiipafea, or 
wie partially burnt, and the metallic ingredients more or less perfectly rediweo 
and in this condition portions or mas-ses ina^ fall to the earth. And the 
ojtaion is not the hnrstUg of a^ass, bat an electric discharge: the prides or 
»w» which fall are por/toM, not/rasmwjl#; and the effect. Instead of l»iiig one of 
tp, 15 one of consolidation; au instance of the universal law which appears 
tiiwil in the fficonomy of the planetar)' world.

^chid object of this communication was to place on record a table of all the 
"“•Adile appearances of luminous meteors which the author has been able to c^- 
[W op to till' present time, supplementary to the very complete list given 
wWit’s second catalogue (Nouv. Mtim. dc I'Acad. de Bruxelles, tom. xv.), which 
'«"(» down to the year 1840. This list is doubtless imperfect; but the author suh- 
•“H it to the Association in the hop« that its deficiencies will be filled up by the
