i8o Mr, Howard's Experiments and Observations 
note,* which observes, that credulous people assert it to have 
fallen from heaven, during a thunder storm, on the 3d of July, 
1 753 - 
The collection of Baron Born, it is well known, has a place 
in the cabinet of the Right Hon. Charles Greville, who, 
from the effect produced by comparing the histories and struc- 
ture of the Italian and Yorkshire stones with the description of 
this iron, was induced to search the collection of Born, where 
he discovered the very substance asserted to have fallen on the 
3d of July, 1753. How far these four substances have resem- 
blance to each other, it will soon appear not to be my province 
to anticipate. 
The President having done me the honour to submit his 
specimens of the Yorkshire and Italian stones to my examina- 
tion, I became indebted to Mr. Greville and Mr. Williams 
for a similar distinction : and, being thus possessed of four 
substances, to all of which the same origin had been attributed, 
the necessity of describing them mineralogically did not fail to 
present itself. To execute this task, no one could be more eager, 
and certainly no one better qualified, than the Count de 
Bournon. He has very obligingly favoured me with the fol- 
lowing descriptions.

The stones I am about to describe, are not of any regular 
shape ; and those which were found in an entire state, that is, 
those which had not been broken, either by their fall or other-
