heard a peculiar rumbling noise very dissimilar to thunder, more like the 
rattling of carriages over a paved street. A man and a boy heard some- 
thing heavy fall without any other noise and collected some of the stones. 
Afterwards others were picked up and about 30 were found scattered 
over an area of about one square mile. All the stones were nearly pyra- 
midal and weighed from 4 to 4 pounds, one however 144 pounds. ‘The

oor variety of brown iron ore. A real fresh fracture shows distinct, 
although slight greasy lustre. The crust is very thin, not over $ line in 
thickness, dark reddish brown mostly dull, only here and there on the 
flat portions and the rounded edges darker inclining to black and some- 
what more lustrous. The whole condition gives the proof of a very 
slight fusibility. Sp. gr. at 17° R.=3:425. Hardness about 6. 
The form of the large stone is very remarkable. Its centre of gravity 
lies evidently in its thicker part, at the opposite lighter and pointed end 
are principally the indications of those flat, basin-like depressions. The 
lower part of the meteorite, as it were the base of it, is remarkably even. 
. Lhe meteoric iron from Tula, Russia.—In the year 1846 a mass 
of iron of over 15 puds (542 pounds avoirdupois) was found 7 versts

was sold for four roubles (three dollars) to the Myschega iron works in 
tion. He has given the first notice of it,* and in a preliminary analysis 
of it found the mass to contain: Iron = 938-5, Nickel —2°5, traces of Tin 
and 0:9 Schreibersite. It yields sulphydric acid, when dissolved in chlor- 
hydric acid, probably owing to the presence of pyrrhotine. Articles manu- 
factured from this iron show after etching a beautifully damasked surface. 
t the meeting of the Imperial Academy at Vienna of Nov. 18th, 
1860, W. Haidinger has communicated some very interesting observations 
made on a specimen of this iron obtained from. Dr. Auerbach. 
The principal mass, although not altogether homogeneous, consists of 
iron, showing indications of Widmannstadtean figures, and imbedded in
