blows given in an effort to break off fragments. The general 

 appearance of these broken parts is a dull, coarse-grained base 

 or cement, with some larger, crystallized, angular grains 

 imbedded. These broken surfaces are very rough and prickly 

 to the touch, and the glass showed sharp points and granules 

 of white iron intimately sprinkled in with a filling of oily 

 green, glassy olivine. M. Tholazan in 1884*" described the 

 inner constituents of the stone, giving them as " bronzite " ; 

 a green, infusible and almost insoluble silicate, probably peck-

hamite ; and granules of nickel iron ; — all cemented by a fine 

 network of nickel iron. Merrill, after examining a small frag- 

 ment sent by me to him at Washington, writes me : " I make 

 out the presence of enstatite, olivine ; a colorless (in the sec- 

 tion) mineral giving an inclined extinction as high as 29° 

 which may be peckhamite : and in addition granules of clear, 

 colorless feldspars, showing distinctly twin striae, and giving 

 an extinction-angle of 30°. This indicates a basic member of the 

 albite-anorthite series, perhaps bytownite or it may be anorthite." 

 The polished section of the mass, as seen in the enclosed 

 cut, has a very close resemblance to the Miney meteorite from 

 Taney Co., Missouri. There is the same compact base of the 

 fine-grained elements, both stony and metallic, with segregated 

 patches of each of them in which the matrix is at once more 

 homogeneous and of coarser structure. Besides the myriad
