The general composition of the meteorite may be arrived at by com- 

 bining- the results of the several determinations, thus : 



Per cent. 



Fe 1 2.37 



Ni 0. 21 



Co • 0. 01 



S 1.61 



P 0. 012 



Si02 4(3. 06 



FeO 14. 33 



Klfi; 2. 20 



Cr^Os 0. 23 



CaO 2.13 



MgO 28. 62 



K^O 0. 10 



Na^O 0. 96 



Residue (chromite) 0. 51 



99. 352 



From these several analyses it is possible to arrive at the following 

 approximation of the relative quantities of the different constituents: 



Per cent. 



Nickel iron 2. 59 



Troilite 4. 43 



Schreibersite .08 



Chromite 80 



Olivine 40. 48 



Pyroxenes 51. 62 



100.00 



In the above the amount of the nickel iron is given as directly 

 determined. The sulphide and phosphide of iron are calculated from 

 the amount of sulphur and phosphorus found; the chromite is simi- 

 larly calculated. The soluble silicate is regarded as olivine; the insol- 

 uble silicate as being largely enstatite, with some augite. 



EXPLANATION OF PLATES. 

 Plate VIII. 



The HeiiderxoHviUe, NorUi. Carolina, Meteorite. 



Fig. 1. The stone as it came into the possession of Professor Glenn. 



2. The portion of the stone now in the U. S. National Museum, viewed from 

 side opposite to that shown in fig. 1. 



Plate IX. 

 Microstructure of Hendersonville, North Carolina, Meteorite. 



Fig. 1. Black areas, metallic iron and iron sulphide; light, olivines and enstatite. 

 Near the center an indistinctly chondritic mass with structure suggestive 

 of sintering of finely pulverized olivines. 

 2. Light and dark areas as in fig. 1. At the ))0ttom an olivine chondrule. 

 Large colorless areas in the upper left quadrant are enstatites. The section 

 shows to advantage the finely pulverulent granular structure characteristic 

 of much of the interstitial matter.
