brown intensely absorptive basaltic hornblende. Pumpelly 
first described this rock in the third volume of the Geology of 
Wisconsin, under the name of augite-diorite,* this name being 
given because he regarded the hornblende as primary and the 
rock as intermediate between diabase and diorite. In the same 
volume I suggested that the hornblende was secondary and 
that the rock was merely an altered gabbro.t This opinion I 
find sustained by a re-examination of Pumpelly’s sections, and 
by the study of a number of new sections. The hornblende is 
found in every stage of growth from an augite crystal, with a 
slight border of hornblende, to a completed crystal without 
trace of augite. 
Thus, after an examination of about a thodsind thin sec- 
tions representing the crystalline schists, acid eruptives and 
basic eruptives of a region some four hundred miles in length 
y in width, and of three distinct geological systems, I 
have found no hornblende that is not either clearly, or very 
probably, secondary to augite.

1. The Bishopville Meteorite. 
THE meteorite which fell at Bishopville, South Carolina, 
March, 1843, has been regarded as an interesting and peculiar 
one. Professor C. U. Shepard in 1846 (this Journal, II, se 
380-381), desmnbed from it, under the name of chladnite 
mineral which he regarded as a tersilicate of magnesia, cad. Pe 
forming over two-thirds of the stone. e color was snow- 
white, rarely tinged with gray. Luster pearly to vitreous, trans- 
lucent. H. 6—6°5 ; sp. gr. 3°116. Fuses without difficulty ‘before 
the blowpipe to a white enamel. He further describes as 
apatoid some very rare, small, yellow, semi-transparent grains, 
having a hardness of 55. A third mineral which he name 
todolite was of a pale smalt-blue color, vitreous luster, brittle. 
Hardness 55-6. Fuses easily with boiling intoa blebby, color- 
less glass. This was found only in a small quantity. 
Later, Shepard gave a fuller account of this stone, holding 
that it cetmmnal chladnite ninety per cent, anorthite six per 
cent, nickeliferous iron two per cent, and two per cent of mag- | 
netic pyrites, schreibersite, comet iodolite and apatoid. The 
chladnite was analyzed and the results will be given below.
