drawn as to the mineral composition of the stone. It is to be noted, 

 however, that qualitative tests show an unusually large proportion of 

 silicate matter soluble in acid, and suggest the need of further chemi- 

 cal work. This must, however, be deferred for the present. 

 The 0.888 per cent of metal yielded: 



Iron(Fe) 92.596 



Nickel (Ni) 6. 152 



Cobalt (Co) 417 



Manganese (Mn) 522

In comparison with the other chondritic stones this offers no 

 unusual features. 



Treated with dilute hydrochloric acid (sp. gr. 1.06) and sodium 

 carbonate solution in the customary manner, the silicate portion, free 

 from metal and metallic sulphide, yielded 22.582 per cent of soluble 

 matter of the following composition: 



Silica (SiO.,) 38. 239 



Alumina (ALO,) trace 



Ferrous oxide (FeO) 6. 566 



Nickel oxide (NiO) 043 



Manganous oxide (MnO) 709
