WELLAND, ONTARIO, CANADA. No. 416. 



Iron, Om. Fragment some 40 by 20 by 20 mm., weighing 38 

 grams, from a mass weighing 8 kilograms found in 1888. The 

 chemical composition, as determined by J. M. Davison, is as follows: 

 Iron, 91.17; nickel, 8.54; cobalt, O.OG; sulphur, 0.07.

Stone, Ccb. Four fragments weighing 4, 6, G, and 17 grams. All 

 from the interior. Fell December 14, 1807, at G.30 a. m. The fall 

 was accompanied by the usual flash of light and detonations com- 

 pared to the sound produced by cannon balls rolling over a floor. 

 The meteor passed from the north toward the west and was in sight 

 some 30 seconds. Six or seven masses were known to fall within a 

 distance of some 9 or 10 miles along the line taken by the meteor, 

 the aggregate weight of which has been estimated at about 330 

 pounds, or 150 kilograms. The largest individual is estimated to 

 have weighed some 10 kilograms. The stone is chondritic, of ash- 

 gray color, with metallic iron and pyrrhotite visible to the unaided 

 eye. Analyses made by Professor Silliman are, owing to the condi- 

 tion of analytical science at that time, of only historical value. The
