Analysis of No. 3 by J. B. Mackintosh: 



Fe Ni Co P 



87.93 11.15 0.33 0.36 =99.77 



Specific gravity of No. 2 about 7.66+. 



Troilite was observed on the crust of No. 1, also traces of olivine and perhaps schreibersite. 



Later Kunz 3 gave an account of the discovery of additional masses and further notes upon 

 them as follows: 



During the month of August, 18S5, Mr. J. H. Bullock thoroughly examined and dug over the ground, working about 

 six weeks steadily, and was rewarded by finding three more masses of the Glorieta meteorite (Nos. 4, 5, and 6). In the 

 meantime a Mexican had also found a small piece (making seven fragments thus far obtained), but it disappeared before 

 Mr. Bullock could secure it. Mr. Bullock states that the pieces found by Mr. Sponsler were discovered while he was 

 prospecting during the month of August, 1884, on the ranch of Mrs. Roival near Canoncito, Santa Fe County, New 

 Mexico, 5 miles from the summit of Glorieta Mountain. 



No. 4 weighs 1.204 kg. (2.65 pounds). One-third of the surface shows the disruption as in No. 2, the other parts 

 being unaffected and showing the crust surface. The broken surface is partially drawn out toward the part that was 

 torn off from it, and one edge shows a fracture suggesting cleavage. The mass is 50 mm. high, 125 mm. long, and 50 mm. 

 wide, or about 2 by 5 by 2 inches. One of the pittings which has been increased in size by the disruption measures 60 

 mm. in length, 25 mm. in width, and 15 mm. in breadth. 



No. 5 weighs 1.126 kg. (2.48 pounds), measures 100 mm. in length, 75 mm. in width, and 48 mm. in height, about 

 4 by 3 by 2 inches. Five-sixths of the entire surface bears the marks of violent disruption; the mass was undoubtedly 

 broken from the upper corner between Nos. 1 and 3. A raised octahedral structure, resembling a coarse network, is 

 revealed on two-thirds of its surface and the pitted side shows evidence of having received a part of the blow. 



No. 6 weighs 1.05 kg. and measures 125 mm. in length, 82 mm. in width, and 45 mm. in thickness at the thickest 

 part. It is quite flat, the fracture having left a surface so flat as to be suggestive of a cleavage. Altogether this mass 

 closely resembles No. 4. 



The 148.5-pound piece (No. 1) was found only 8 feet from the 115-pound (No. 2) and the 53.5-pound (No. 3) pieces, 

 while the small pieces picked up by Bullock and the Mexican were 45 or 50 feet from the large mass, being hurled 

 farther on account of their lightness. The fact that the pieces lay so near together proves conclusively that the meteorite 

 did not burst in mid-air. The pieces were all embedded in the vegetable mold which covered the rock at that place, 

 the largest piece to the depth of 10 inches. 



Nearly the whole of the large mass (No. 1) has been cut into slices. The iron is seen to be very homogeneous through- 

 out with the exception of an occasional space measuring 1 mm. to 4 mm. across. One of these spaces near the center 

 of the mass was evidently formed by the shock of disruption. In a few instances this explanation is verified by the 

 curving of the Widmannstatten figures, showing that nearly every part of the thick mass was twisted and wrenched when 

 it burst asunder with such tremendous force. The ruptured surface on Nos. 1 and 3 shows large patches of troilite. In 

 cutting No. 1 large streaks of this mineral and also some schreibersite were observed. The largest of these lines of 

 troilite was 10 cm. longand 4 mm. wide. Two of the streaks, 10 cm. apart, ran parallel to each other in peculiar crescent- 

 like formations. Olivine was observed at the upper end of No. 1, a surface of about 10 cm. square being completely 

 filled with it. The color in some instances was a rich brownish yellow, homogeneous throughout, and as compact as in 

 the " Pallas iron." The largest grains observed measured from S mm. to 14 mm. Some of these pieces yielded perfect 

 transparent gems (peridots) over 4 mm. in width. 



The discovery of a seventh mass regarded as silver bullion and sent from Albuquerque was 

 described, as well as the mass itself, by Eakins 2 as follows: 



A seventh mass, found near Albuquerque, New Mexico, is referred to this fall. It was mistaken for silver by the 

 finder. Originally of triangular shape, it measures 120 by 80-100 by 45 mm. Before cutting it weighed 2.5 kg. When 

 found it was covered with a thin oxidation coating. The iron composing this meteorite is exceedingly tough and free 

 from cavities. The etched surface shows very well-defined Widmannstatten figures.

Cohen and Weinschenk 6 studied several features of the meteorite as follows: 



Of Glorieta Mountain three pieces were investigated; two from the Greifswald collection, the third from the 

 Vienna collection. The Vienna material was slowly soluble in dilute HC1, that from Greifswald was hardly attacked, 

 doubly concentrated acid being necessary to affect it, and this at first only weakly, but after some time more uniformly.
