342 Analysis of the Braunau Meteorite. 
The fluid was poured off from them in part, the remainder 
being removed by filtration. This residue was then dissolved in 
a few drops of nitric acid, the solution evaporated to dryness 
with a small quantity of soda and heated before the blowpipe 
upon a platinum wire. A bluish green color was developed, indi- 
cative of the presence of manganese. 
The transparent filtered fluid was again supersaturated with 
sulphuric acid, evaporated to half its volume and then filtered ; 
this liquor was then tested with the ammoni solution of a 
nesian salt for phosphoric acid, but even after a lapse of a 
considerable time no precipitate was observable. 
From the above it appears that the Braunau meteoric iron, both 
in a qualitative and quantitative point of view, bears a very close 
resemblance to that of Bohumiliz. Its constituents are, as deduced 
from the foregoing experiments, in the hundred parts, as follows:

Since the completion of this analysis, the remarkable fact has 
been established that the Braunau meteoric iron is not homoge- 
neous throughout, but that it contains nodules of iron pyrites 
(in which Professor Fischer—according to the ‘ Schlesische 
Zeitung,” of the 14th of October—has detected charcoal, phos- 
phorus and chromium.) We are in the first instance indebted for 
this fact to that liberal Prelate, Dr. Rotter, Abbot of the Bene- 
dictine Monastery at Braunau, who generously permitted por- 
tions to be sawed off from the mass that fell at Hauptmansdorf 
for various institutions at Breslau, for Baron Humboldt, and for 
the public collection of minerals at Berlin. : 
This latter specimen, one of very considerable size, contains 
one of these nodules. ‘ 
(The occurrence of both white and yellow iron pyrites in the 
American meteoric irons, has been repeatedly mentioned in this 
Journal both by myself and by Prof. Shepard. The mode of 
occurrence of these nodules, is clearly shown in the fac simile 
copy of the etched surface of the Lockport iron, in this Journal,
