THE MEXICAN METEORITES.

implements. Many specimens are in the various European 
collections and at least fragments are in the collection in 
the city of Mexico. In 1856 Gustav A. Stein reported that 
in 1854 he visited the country in the vicinity of Xiquipilco 
to learn more of the meteoric irons. He there got informa¬ 
tion of at least four specimens, weighing in the aggregate 
545 pounds. The weight of all the specimens found in that 
vicinity can never be known. It is probable that the speci¬ 
men in the Poinsett collection was from Toluca valley. 
. ‘ The State of Morelos. 
22. A specimen of iron from Los Amates forms a part of 
the collection of Castillo, and a specimen from Cuernavaca 
is in the National Museum of Mexico. Castillo gives no 
weight for either specimen. 
The State of Oaxaca. 
23. The Yanhuitlan mass is said to have been found by 
Indian laborers while tilling the ground at the foot of a hill 
near Yanhuitlan. It was used by a blacksmith for several 
years as an anvil. In 1864 it was removed to the city of 
Mexico and is now in the National Museum of that city. 
Many small fragments were removed before it was carried to 
Mexico, but its weight is now 421 kilograms. The so-called 
Cholula mass, the Chaleo mass, and the Misteca Alta frag¬ 
ments all probably refer to the Yanhuitlan mass. 
The State of Guerrero. 
24. The Caparrosa mass was found in 1858 by Castillo on 
breaking a piece of copper pyrites which had been brought 
from the Rincon de Caparrosa. It was a nodule of metallic 
iron weighing 341 grams, and when etched it showed Wid¬ 
manstatten figures. 
The information in regard to many of these meteorites is 
far from being as complete as it should be.
