S*4 Account of a Fire-Ball which felt 



«tone in acids have a more intense green colour than thafc 

 which, as appears, ought to arise from the iron it contains/ 



*' On pulvenzing this stone there were detached globules 

 of iron, one of which weighed about 24 grains. Its colour 

 is whiter than that of ordinary iron, and, though ductile, it 

 is harder than bar iron. It contains sulphur and nickel. 

 Whence it appears that the sulphurated hydrogen gas and 

 nickel found in it arise from the iron it contains. 



" The three parts which are in excess in the result of the 

 anal^'sis arise from the oxygen absorbed by the iron. It 

 ought even to have acquired more of it, and consequently 

 there must be a loss. 



" The experiments of Mr. Howard on the same subject 

 have been published in the Annales de Chiwic, and you 

 will see that'my analysis has a great relation to his. You 

 ou'^ht to place the more confidence in it, as 1 obtained the 

 same results before I was made acquainted with those of 

 Mr. Howard *. 



\ XXXVT. Account of a Fire-ball which fell in flie Neigh- 

 bovrhood of Lctigle : in a Letter to the French Minister 

 of the Interior. Bij C. Biot, Member of the National 

 Institute, dated Jidij 20, 1803. 



J. READ ycsterdav to the Institute an account of the journey 

 I lately undertook by your desire in consequence of the me- 

 teor of Laigle. It has been ordered to beprinjled. An ex- 

 tract from this account may be interesting to you who have 

 contributed to place this astonishiiag phienonienon beyond 

 a doubt, and perhaps to the Chief Consul, u ho amidst so 

 many labours still finds means to devote some moments to 

 the sciences. 



Whei\ [ set out from Paris on the 26lh of .June, I did not 

 proceed directly to Laigle. Had the explosion been as sud* 

 den as was announced, it must have been heard at a great 

 distance. It was therefore agreeable to the rules of criti- 

 cism, first to collect scattered testimonies, and to sutler 

 myself to be gradually conducted by them to the place 

 where the meteor was said to have burst ; for in regard t(i 

 all the circumstances of the explosion the accounts could 

 not but agree, in whatever part they might be collected. 



* In the nexr Number we shall give an account of the stones which 

 fell ill the Djighbourhood of Euihiautim and ot A^c:., tukvii from the 

 same bourcc.
