ANDOVER. 



Oxford County, Maine. 

 Latitude 44 36' N., longitude 70 42' W. 

 Stone. Spherulitic chondrite (Cc) of Brezina. 

 Fell August 5, 1898, 7.30 a. m.; described 1902. 

 Weight, 3.17 kgs. (7 Ibs.). 



This stone fell on the farm of Mr. Lincoln Dresser hi Andover, Oxford County, Maine. 

 Ward l gives the following account of its fall as stated by Dresser: 



Mr. Dresser was within 25 feet of it when it fell. It came from the northwest at an angle of 75. It was accompanied 

 by a loud noise resembling that of a buzz saw, and left a trail of blue smoke. It was intensely hot when it struck and 

 grazed a stone wall. In its fall it passed down through the branches of an elm tree, cutting many of them off as clearly 

 as if done with a sharp knife. I supposed at the time it was a gaseous ball of fire, and thought it exploded, but after 

 examination I found where it embedded itself in the earth to the depth of 2J^ feet. I secured, by digging, a 

 large piece weighing 7.5 pounds, and two or three small ones which were broken by striking the rock fence. This 

 represents probably about half of the meteorite, as a large broken surface was apparent when it was found. People 

 in the adjoining towns heard the peculiar buzzing noise, and a loud report, probably when it burst. 



In June, 1902, Ward visited the spot where the stone fell, and states: 



A sharp dent in the granite wall still showed freshly where the stone struck in its first impact. In falling it had 

 passed through thickly set, small branches of an elm tree directly above. Mr. Dresser said that it was seeing these 

 branches fall, cut off by the stone, which had changed his first impression of the gaseous character of the phenomenon. 

 I obtained a portion of a branch 2 inches in diameter, half cut through by the meteorite. The large mass weighs 6.5 

 pounds. In general shape it is an irregular lengthened polygon like a flattened triangle, with the three points largely 

 truncated. One side measures 7.75 by 4 inches; the opposite side, which was broken off by the fall, is of the same 

 length, but 5.5 inches in measure at right angles. All other sides are well coated with a brownish-black crust, relieved 

 by occasional patches of lighter brown. The crust is roughened by. little, slightly raised pimples, often connected 

 with very short ridges of the molten matter. On several sides are shallow pittings as large as the impressions of finger 

 ends. Some of these are separated, others confluent, the latter, as is to be expected, all on the same side of the mass, 

 having their depressed rim in the same direction or aspect. The broken side of the mass shows an interior of a light 

 gray color, and is granular, with a few chondri of a much darker color. The whole mass is, in a fresh fracture, brilliant 

 with points of nickeliferous iron sparsely interspersed with bronze-colored troilite. 



The mass is now chiefly in the possession of Mr. Henry V. Poor, of Brooklme, Mass.

APOALA. 



Oaxaca, Mexico. 



Latitude 17 40 / N., longitude 97 0' W. 

 Iron. Fine octahe'drite (Of) of Brezina. 

 Weight, 85 kgs. (187 Ibs.). 



The first published mention of this meteorite seems to have been by Cohen 1 in 1901. He 

 considered it at that tune a piece of Misteca. He called attention to the markedly granular 

 structure of the kamacite and compared the iron with Teposcolula and Moctezuma. 



Ward's catalogue 2 of 1904 stated that the main mass of 85 kilos was "in the Museum 

 of the Instituto Geologico, City of Mexico, not yet described." It was also stated that Apoala 

 is 10 miles east of Coixtlhuaca. 



Cohen 3 in 1905 further described the structure as follows: 



According to a small piece, quite insufficient for a proper characterization, Apoala consists of short, puffy, irregularly 

 bounded lamellae, which are hatched only in exceptional cases. Where several lie close together, they are, as a 

 rule, divided by small particles of plessite. The kamacite is composed of irregular grains of variable form, which 

 are sometimes much less distinctly divided from one another than usual, attain a diameter of 0.1 mm., and show the 

 same oriented luster. The tsenite is markedly developed. The fields are less prominent than the bands and the 

 smaller ones, which consist of compact, dark plessite, are sometimes intersected by one or more fine lamellae which 

 are united with the principal lamellae, at one or both ends. In the larger fields the structure of the iron as a whole
