504 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.48. 



Minnesota, aerolite approximately 16.4 cm. by 10.6 cm. by 8.1 cm., 

 weighing 1,765 grams, with crust well preserved. One curved sur- 

 face shows the original crust and there are about six fractured sur- 

 faces showing a secondary, tertiary, or perhaps quarternary crust 

 with pittings and flowage lines." Doctor Hovey further states that 

 a second mass from the same source, weighing 1,850 grams, was sent 

 by the American Museum to Doctor Gottsche of Hamburg. These 

 two stones were originally in the possession of Dr. G. F. Kunz and 

 are beyond doubt the two found in 1895 as mentioned by Mr. Sweet 

 above. A third fragment, weighing 28 grams, he also records as 

 having passed in 1913 into the hands of the dealer, W. M. Foote, 

 and 22 grams are listed by Doctor Berwerth in his collections in the 

 Vienna Museum. Dr. O. C. Farrington reports, in answer to inquiry, 

 that the Field Museum collections include three fragments weighing, 

 respectively, 133, 185, and 277 grams. Two of these are doubtless 

 from the Ward-Coonley collection mentioned in the catalogue of 1904. 

 It would seem practically certain that all of these fragments were 

 from the larger mass mentioned by Winchell, the principal portion 

 of which is lost. The distribution and weights as known to-day are 

 then as follows:

Through the courtesy of Prof. W. H. Emmons of the University 

 of Minnesota, the writer has had the opportunity of examining the 

 stone in the possession of that institution and was also granted per- 

 mission to cut from it a sufficient amount to guarantee its identity 

 with that in the Museum collections and to supplement sufficiently 

 that cut from our own specimen to insure a satisfactory chemical 

 analysis. 



The general appearance of the stone on a broken or polished surface 

 is closely similar to that of Forest City, Iowa, and still more to that 

 of Coon Butte, Arizona. 3 The stone is of a compact texture, suffi- 

 ciently firm to admit of a polish, of a light gray color, and is thickly 

 spotted with metallic points in sizes up to 3 mm. in diameter with 

 numerous small, distinct, light gray chondrules and more rarely 

 larger (2 mm.) white forms. Each specimen examined shows one 

 curved, crusted area, with few distinct pittings, evidently a portion
