The percentage of cobalt is unusually high. Specific gravity as 

 made on different samples from the mass, 6.36, 6.60, and 6.92. This 

 iron was subsequently studied by Brezina, whose results differed 

 greatly, so far as proportional amounts of the varying constituents 

 are concerned. He found : 



Per cent. 

 Nickel-iron 96. 97 



Schreibersite 2. 52 



Carbon .09 



Chromite and silicate granules .01 



Undetermined residue . 41 



100. 00 



Omitting the undetermined residue and certain angular pieces 

 separated in solution, he obtained for the iron :

Iron (Fe) 91.52 



Nickel (Ni) 7.12 



Cobalt (Co) .84

Carbon (C) .10

Stone, Chla. AVeight, 102 grams; two fragments from the interior. 

 Fell March 25, 1843. Original Aveight, 13 pounds (6 kilograms). 

 This is a very interesting and somewhat unique stone belonging to 

 Tschermak's group of chladnites, of which but four representatives 

 are at present known. The stone was first described by Shepard in 

 1846 as consisting in large part of a light gray material regarded by 

 him as a persilicate of magnesia to which he proposed to give the 

 name chladnHe., in honor of the chemist, Chladni. Subsequent re- 

 searches (in 1864) by J. Lawrence Smith showed the mineral to be 

 identical with enstatite. In addition to this, Shepard thought to dis- 

 cover two other new minerals, the one blue and the other yellow, to 

 which he proposed to give, respectively, the names iodoUte and apa- 

 toid. These have since been shown to be oxidation products of the 

 nickeliferous iron, or pyrrhotite. The stone was described in 1851 by 

 W. Sartorious von Waltershausen, who thought to show that the sill-
