Next a portion of the meteorite was analysed without 

 previous treatment with hydrochloric acid, so that the 

 following results give the composition of the meteorite as 

 a whole. Dried at 110°, loss == '543°/°. 



Silica ... 39*470 



Copper none 



Tin none 



Alumina 2*870 



Iron sesquioxide 9*176 



Iron monoxide 17*056 



Nickel 1*010 



Cobalt none 



Manganese ... ... ... ... ... ... traces 



Lime 1*605 



Magnesia 25*583 



Soda (Na 2 0) ... '735 



Potash (K 2 0) -109 



Chlorine... ... ... ... ... ... ... trace 



Sulphur 2*299 



Phosphorus ... ... ... ... ... ... *100 



Less oxygen = to sulphur and phosphorus 



100*013 

 1*349 



98*664 



Chromium, vanadium, etc., were specially sought for, 

 but not found. 15*5 gms. crushed in a diamond mortar and 

 ground in an agate mortar yielded 3 or 4 specks of a yellow 

 non -magnetic metal soluble in nitric acid and therefore 

 not gold. 



The above amount of sulphur if assumed to be in com- 

 bination as FeS, would represent 6*2°/° of troilite and the 

 # 109 o /° of phosphorus would represent 1*6°/° of Schreibersite 

 (FeNi) 4 P; if the whole of the nickel be also assumed to be 

 present as (FeNi) 4 P, it would represent 2' If of Schreibersite. 

 The nickel and cobalt were determined by electrolysis
