180 Dr. Chladni’s Continuation 
1824, about February. At some distance from Irkutsk, a 
large stone, according to newspaper accounts from St. Peters- 
burg. 
1824, 14th of October. Near Zebrak, in the circle of Beraun, 
in Bohemia, a stone, according to Hallaschka, in Schumacher’s 
Astron. Nachr. No. 70. 
? Small crystalline stones, or perhaps small pieces of mag- 
netic pyrites, which (according to an account of Dr. Evers- 
mann, communicated by Professor John, in the Annalen der 
Physik, v. \xxvi. p. 340; and in Kastner’s Archiv fiir Natur- 
kunde, v.iv. p. 2. p. 196) fell at Sterlitamansk in the govern- 
ment of Orenburg. It is however doubtful whether they be- 
long to the class of meteoric stones, or whether they form a 
concretion of a peculiar kind. 
(The pretended rain of stones mentioned in the newspapers 
as having fallen near Torresilla de Carneros in Spain, the 25th 
of July 1825, seems to have been nothing but common hail, 
of which pieces weighed as much as from 5 to 16 ounces.) 
II. Additions to the List of solid Masses of Iron containing 
Nickel. 
A. Cellular Masses of solid Iron, with Portions of Olivine in 
the Interstices. 
The analyses of the olivine.contained in such masses made 
by Counsellor Stromeyer are very remarkable, since they 
establish: 1. that the olivine of such masses contains no 
nickel; 2. but that, on the contrary, all other olivine and 
chrysolite contains nickel; 3. that olivine, chrysolite, and the 
species of stone of such solid masses of iron, belong to the 
same class*, 
To these masses we have to add one found in the year 1809, 
in the vicinity of Brahin and Rzeczyca, in the government of 
Minsk, which seemed to have failen a short time previously. 
Further particulars of it are given in the Journal fiir Chemia, 
&c. new series, vol. xiil. h. 1. p. 25+. 
B. Solid Masses of Iron containing Nickel. 
The mass found near Bitburg has been melted, through 
ignorance, and fragments of it have been again discovered by 
Professor Neeggerath : according to the analyses of Professor 
Bischof and Counsellor Karsten, they are of this kind f. 
Besides the masses of iron found in Louisiana near the Red 
River, and mentioned before, several more have been found,
