A Supposed new locality of Meteoric Iron in Mexico. 
_ When landing the above described iron from the steamer on 
-my arrival at New York, it accidentally fell under the observation 
of Mr. Peter McDermot, a deputy custom-house, officer, whose 
attention was arrested by its perfect coincidence in size and gen- 
eral configuration with a mass he had seen in 1847 at Ceralvo, 
a town situated halfway between Camargo and Monterey, on the 
great road from this country to Mexico. Mr. McDermot was 
then a first sergeant in the United States service ; and met with 
the mass in a well known blacksmith’s shop at Ceralvo. It was 
there used as an anvil, one of its faces having been smoothed off 
to fit it for the purpose. His curiosity was much excited at the 
time, by the peculiar indentations upon the surface of the mass: 
and never having seen anything of the kind before, he was led 
‘to doubt whether the metal was really iron. Being a blacksmith 
by trade, he made a cut into its side with a cold chisel, in order 
to satisfy his curiosity upon the subject. The experiment left 
no doubt in his mind, that it was composed of soft, tough tron. 
He had never seen or heard of an undoubted specimen of mete- 
oric iron except on the present occasion ; and after inspecting 1, 
felt no doubt that the anvil he had examined at Ceralvo belonged 
to the same class of objects, and had a similar origin. It is to be 
hoped, that this notice may lead to an early recognition and test- 
ing of the iron seen by Mr. McDermot. a
