'The stone received in Vienna was perfect, that is, it was covered on all sides with 
a distinct crust, hut at the same time, judging from its shape, it was truly an angular 
fragment of a rock-mass, which burst long prior to its reaching our atmosphere. It was a 
somewhat conical fragment, rather sharply angular in one direction, where the sides, 2 to 
3 inches broad, meet at an angle of about 60°. In the other directions, the three sides 
meet at angles of from 90° to 105°.’ 
‘ The surface is rather uniformly coated with a crust of about T A 5 th of an inch in thickness. 
This black crust is dull, fine grained, and on all planes covered with the well known and 
characteristic round shallow impressions. The stone was about 4 inches long, 3 broad and 2 
thick. One side was rough, the other more even, before the incrustation, but both are simi¬ 
larly incrusted. Even at the sharp angles, no molten edges are traceable which would 
indicate that the stone had passed through the atmosphere only in a given direction.’ 
‘ The fresh fracture of the stone, and especially the cut and polished surfaces, showed 
that the stone undoubtedly belonged to the group of falls indicated by Partsch, and including 
Eichstiidt, Barbotan, Bielaja Zerkow, Timochin, Zebrak, Gross-Divina, to 
which must since be added Pokra (Bustee). These are all grey, more or less dark coloured, 
locally brown, with more or less globular portions distinguished from the rest of the mass 
by a nearly black colour with much finely divided iron, a little pyrites, and probably troilite. 
The Pultusk stone is very similar to that from Gross-Divina. Its specific gravity is 3660 
(Sehrauf.), which indicates the large proportion of iron it contains. The average specific 
gravity of the group was determined by Partsch as 3'55 to 3'70.’ 
The stone would belong to the third class, sporadosuleres, and to the second sub-division 
of that class, oligosideres, of Mr. Daubrde’s classification.—(T. 0.),
