W. E. Hidden — Two masses of Meteorie Iron. 465 



similar spots of this same rare species were noticed on the face 

 shown in fig. 4. Their deliquescence first attracted attention 

 to them. The presence of hydrogen (occluded) was proved by 

 simply rubbing the smoothed surfaces with powdered sulphur, 

 when instantly, the disagreeable odor of hydrogen sulphide was 

 made noticeable. In the action of nitric acid on the smoothed 

 surfaces the presence of carbon was also proved conclusively. 



A few words as to what seems to be the point of impact 

 when this mass fell. By referring back to fig. 8 and noticing 

 the lower right hand edge a nearly straight 

 surface of two centimeters length is seen, 

 and as this was a natural flat surface I 

 smoothed and etched it, with the result as H-- ',".*> > 

 shown in fig. 5. A set of lines, of structure K| ' Ati , 

 at about 90° angle, is at once noticeable, as ^'j';,!;'^,;,^ 

 well as an increased fineness of detail as com- 

 pared to the other figures. That this face 

 is the place of impact the writer has no 

 doubt after comparing its surface with the 

 other figures. 



A careful analysis by Mr. James B. Mackintosh yielded : 



Iron 85-33 



.Nickel 13-34 



Gobalt 0-87 



Phosphorus 0-16 



99-70 

 Sulphur, trace. Carbon, undetermined. 



These results place this mass among the few that are exceed- 

 ingly rich in nickel and cobalt. It approaches in this regard 

 the meteorites of Babb's Mill* (Green Co., Tennessee), Ni 14'73 

 per cent [mean of three analyses], and that of Kokomof (Howard 

 Co., Indiana), Ni 1229 percent. Its cobalt percentage is prob- 

 ably above that of any other on record, being nearly 1 per cent. 



The Widmannstatten figures resemble in their perfection and 

 abundance, those shown on the Smith Mountain;}; (Rockingham 

 Co., N. C.) iron described by Smith. This is the fourth mete- 

 oric mass found in South Carolina; the others being known 

 under the names of the Bishopville§ (stone) ; Chesterville ;|| and 

 Lexington County ^[ (Ruff's Mt.) meteorites. 



I take pleasure in here expressing my thanks to Mr. Mack- 

 intosh for his kindness in furnishing the above analyses.
