The dimensions of the mass are 50 cm. in width (C-D) and 50.3 

 cm, in height (A-B) as figured in plate 1. The maximum thickness 

 3|^ (F-E, pi. 2) is 21.5 cm.; weight 68ft0 kilograms. With it was a 

 fragment which had been broken from the edge weighing 420 grams, 

 'O which brings the total weight received to ^&#1 kilograms. An esti- 

 mate that at least a kilogram had been broken away and not received, 

 «^ • places the original weight at approximately ^65- kilograms. 



As noted, the form of the iron is such as to excite interest (see 

 pis. 1 and 2). From a maximum thickness at the point (E) it 

 bevels out gradually in directions toward the left and top — in the 

 figure — to knife edges; to the right and toward the bottom the 

 sloping is abrupt. The shape is such as to suggest a rough quarter 

 section of an original discoidal mass, convex above and concave be- 

 neath and thickest in the center, which has been broken out so as to 

 include a considerable part of the original central portion. That the 

 point (E) represents the nose, or hrustseite, is self-evident as is the 

 fact shown by the sculpturings that it has traveled some little dis- 

 tance in this position. The finer sculpturings, if such they were, 

 have become obliterated through oxidation, as have also any signs of 

 the flowing back over the edges of molten material. The sculptur- 

 ings on the lower surface (fig. 2, pi. 1) are large and of sufficient 

 depth to cause a considerable concavity. 



An etched surface on the edge of the fragment from point (C) 

 shows the iron to be a coarse octahedrite of no unusual features. 

 The composition, as shown by Earl V. Shannon's analysis below, is 

 also devoid of any unusual features unless absence of chromimn, 

 platinum, and manganese be so considered. 



A portion of 10.5746 grams, free from scale, was used by Mr. 

 Shannon for the analysis. The method, with minor variations, was 

 the same as that used for the Odessa iron and described in detail 

 in that report.^ The composition of the Oakley is as follows: 



Insoluble 0.004 



Iron (Fe) 92. 374 



Nickel (Ni) 7. 038 



Cobalt (CO) .273 



Manganese (Ma) None. 



Platinum (Pt) None. 



Phosphorus (P) . 280 



Copper (Cu) .006 



Chromium (Cr) None. 



Sulphur (S) . 016 



Total 99.991 



The almost unweighable amount of insoluble material was 

 examined microscopically. It seemed to consist of a few grains
