mained in the insoluble residue. The silicate decomposed by 
acids containing lime is most probably either anorthite, labrado- 
rite or a lime-olivine. The large portion of magnesia and iron 
insoluble in acid indicates the presence of a pyroxenic mineral, 
Further investigation is needed to fully establish the specific 
character of the constituent minerals of this meteorite, although 
we are justified in concluding that it contains an olivine, a py- 
roxenic mineral and a feldspar, besides chromite, troilite and a 
very small amount of niccoliferous iron. I think by sacrificing 
a large Ry of this stone that its constituent minerals could 
same in character. It seems to belong to the class of meteor- 
ites that Prof. G. Roset calls Howardite, and which he de- 
scribes as being granular mixtures of olivine, with a white silicate 
(anorthite ?) and a small amount of chromite and niccoliierous 
iron. This class, according to Rose, includes the stones’ from 
Loutalox, Bialystok, Massing, Nobleborough and Mallygaum. 
_I take pleasure in expressing my thanks to Mr. Hooper. for 
his generosity in placing the stone at my disposal for examina- 
nation, and to Mr. Pybas for his great interest in furnishing 
the data connected with its fall.
