42, Composition of meteoric stones. — The presence of 

 Nickel, as one of the ingredients of aerolites, has been so 

 generally ascertained, that it is considered almost as an es- 

 sential or invariable characteristic. Laugier, however, has 

 given an analysis of the large stone which fell at Juvenas 

 on the 1 5th June, 1821, in which he states the entire ab- 

 sence of Nickel, and the existtjnce of a portion of chrome. 

 One hundred parts of the stone afforded

A previous analysis of a meteoric stone which fell at Jon- 

 zacthe 13th June 1819, afforded this able chemist the same 

 results and confirmed him in the accuracy of his examina- 

 tion. Vauquelin, also, who examined the aerolite of Juve- 

 nas discovered no nickel, but recognized the existence of 

 chrome, as well as the other ingredients, stated by Laugier. 



The complete absence of nickel, and the almost entire 

 disappearance of sulphur and magnesia, replaced by an a- 

 bundant quantity of lime and alumine, establish between 

 these two meteoric stones and those which have been pre- 

 viously known, a very marked difference. 



Another example of the non existence of nickel occurs in 

 a stone which fell in Finland, on the 13th of December, 

 1813, analysed by Nordenskiold, a pupil of Berzelius.
