The mineral composition of this stone is essentially olivine and 

 enstatite in nearly equal proportions, with 23.06 per cent nickelifer- 

 ous iron and 1.3 per cent chromite. Structurally, it is chondritic and 

 tufaceous, the chondrules showing in some cases undoubted evidences 

 of their fragmental nature before the stone consolidated in its present 

 form. Extremely friable; color light ash gray.

ANGRA BOS REIS, RIO D£ JANEIRO, BRAZIL. No. 111. 



Stone, A. Fragment weighing 8.5 grams, with shining black crust. 

 The fragment is interesting as representing the rare group of angrites, 

 or stones which are composed almost wholly of the mineral augite. 



ARISPE, SONORA, MEXICO. Nos. 299, 325. 



Iron, Ogg. Two samples; an etched slab 48 by 28 by 2 cm., weigh- 

 ing 9,695 grams, and a complete individual weighing 52,727 grams. 

 Found in 1898 in northeastern Mexico. Nothing known regarding 

 fall. The slice shows an interrupted line of troilite masses, which, 

 together with the crystallization brought out by the etched figure, 

 indicates that it is made up of two differently oriented masses welded 

 together. A partial analysis by Whitfield yielded: iron, 92.268;
