The small globules which are commonly met with in me- 

 teoric stones, which Howard had already observed, and en- 

 deavoured to analyse, were not attracted by the magnet. On 

 examining these globules M. Berzelius found, as had also 

 Howard, that they were not a different description of mineral 

 from the meteorite itself (or that they do not differ from the 

 meteorite in which they occur). 



The magnetic portion, or the meteoric iron, consisted of, 



Iron 93-816 



Nickel 5-053
