M. E. Wadsworth—Bishopville Meteorite. _ 33 
The stone was next investigated by W. Sartorius von Wal- 
tershausen. He described it as chiefly made up of a white sili- 
ceous mineral forming a finely crystalline mass, with here and 
there little points showing metallic luster, also grains of mag- 
netite and brown oxide of iron. The hardness of the white 
mineral was given as six, and the specific gravity as 3:039. 
His analysis is given below. His results indicated that the 
former he found to be monoclinic and related to wollastonite 
in ea preety, © color, texture, hardness and crystalline form 
(Ann. Chem. Pharm., 1851, Ixxix, 369-370). Later Professor 
J. Lawrence Smith ¢ stated that from some of his investigations 
“ chladnite is likely to prove a pyroxene” (this Journal, 1855, I, 
xix, 168); and in time he published a furthe r discussion giving 
an analysis which will be found below. Asa conclusion from 
his results he said of chladnite: ‘It is identical in composition 
with Hnsiatite of Kenngott” (ibid., 1864, xxxvili, 225, 226). 
Harlier than Smith’s Jast paper, some investigations were made 
upon this meteorite by Professors Carl Rammelsberg and Gus- 
tav Rose. The former held that the yellowish-brown and 
bluish-gray particles (the apatoid and iodolite 6f Shepard) arose 
from the oxidation of the nickeliferous iron or the alteration 
of the pyrrhotite. 
The analysis of Rammelsberg is here given in connection 
with those of Shepard, ped.cdirer-oe and Smith.

Rose’s examination showed that the chladnite fused before 
the blowpipe only on the edges to a white enamel (Abhandl. 
Berlin. Acad., 1863, pp. 117-122). Rammelsber rg, in ues con-
