The crust of this one on three sides had a blackened surface with 

 shallow dents like finger points. The broken part shows a gray rock, 

 looking like silver. The break was fresh, and on exposure to the air 

 you could observe the iron coloring in it. It was of the finest of 

 granite. People in the adjoining towns heard the peculiar buzzing 

 noise, and heard a loud report, probably when it burst." 



In June, of the present year, I had the privilege of visiting the 

 spot in Andover where the stone fell. A sharp dent in the granite 

 wall still shows freshly where the stone struck at its first impact. In 

 falling it had passed through thickly set, small branches of an elm 

 tree directly above. Mr. Dresser tells me that it was seeing these 

 branches fall, cut off by the stone, which had changed his first instant's 

 impression that the latter was of a gaseous character. 



By the aid of a ladder and a saw I obtained the portion of a 

 branch two inches in diameter, half cut through by the meterorite. I 

 also obtained two small pieces of the stone itself, one from Mr. 

 Dresser, and another from Mr. E. M. Bailey, also a resident of 

 Andover. Through the kind favor of Mr. Poor I am able to here 

 present a cut of the large mass which weighs about 6^ lbs. (Fig. i, 

 plate VIII.) 



In general shape it is an irregular lengthened polygon like a flat- 

 tened triangle, with the three points largely truncated. The cut 

 presents one side whose largest dimensions are 7^ inches in length 

 by 4 inches in greatest breadth. The opposite side which was broken 

 off in the fall is of the same length, but 5}4 inches in the 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 much darker color. The whole mass is, in a fresh fracture, brilliant 

 with points of nickeliferous iron sparsely interspersed with bronze- 

 colored troilite. I have given the name of Andover to this meteorite 

 from the proximity of its fall to the town of Andover, Oxford Co., 

 Maine.
