The mass of stone which accompanied this was somewhat ovoidal ; it
weighed four pounds, measuring fifteen inches round the larger, and eleven
round the shorter, axis. It was covered over with a black-looking vitrified
crust, about one-twentieth of an inch in thickness. This refused to yield
to the action of muriatic, nitric, or sulphuric acid. One end of it was
marked with impressions such as a slightly softened body might receive on
being thrown violently against the earth. The sp. gr. of the crust was a
little over three, or somewhat heavier than marble : it had not been quite
accurately determined, from the difficulty of separating the crust from the
interior. The interior of the aerolite was exactly like softish white sandstone—it
crushed between the fingers, and absorbed, when immersed an hour in water, one-
hundredth of its weight. Its specific gravity was 3 * 5 , or a third heavier than
the heaviest sandstone j that of quartz being 2 ’ 8 . It slightly effervesced withmu«.
riatic acid, giving off much sulphuretted hydrogen gas, and then slowly dissolved
into a glairy mass. It seemed full of metallic particles, which shone beautifully
under a moderate magnifying power, with direct light. The following note by
Dr Giraud gives particulars of the results of the first examination of its
characters :—
The stone is acted on by cold hydrochloric acid, with disengagement of
sulphuretted hydrogen. Boiling, but not cold, nitric acid acts on it violently,
disengaging HS and N04. The great mass of the stone is silica : the metallic
granules consist of iron in large proportions, with nickel and chrome—in fact,
meteoric iron. The nickel of course is much obscured by the iron : the chromine
was readily detected, for on fusing the stone with nitre, dissolving the fluid mass
m distilled water, and then testing with acetate of lead, a fine yellow chromate
of lead was obtained. On fusing the stone with nitre, chromate of potash was
