18. The Catorce Masses. —(1.) The Descubridora mass, weigh¬ 
ing 570 kilograms, is said to have been discovered between 
1780 and 1783. It is now in the National Museum in the 
city of Mexico. The rt Yenagas ” mass described by J. Law¬ 
rence Smith is supposed to be identical with the above. 
(2.) Between 1828 and 1834 Burkart saw at Zacatecas, in 
the possession of an Italian named Chialiva, a complete mass, 
rounded in form, weighing “ 10 or 12 pounds/’ and said to 
have come from Catorce. Nothing is known of it since. 
(3.) A mass weighing 41.7 kilograms was found by a miner 
near Catorce in 1885. It is now in the collection of G. F. 
Kunz. 
19. The Charcas Mass. —Sonnenschmid, in 1804, says this 
mass was situated at the corner of a church-yard at Charcas 
and had been brought there from the neighborhood of San 
Jose del Sitio, about 12 leagues distant. This location cannot 
now be identified. This mass, which weighs 780 kilograms, 
was carried to France in 1866 and is now in the Paris collec¬ 
tion of meteorites. 
It is not improbable that the Catorce and Charcas masses 
came originally from the same locality.

20. The Zacatecas mass in 1792 was in St. Domingo street, 
in the city of Zacatecas, and was said to have been found by 
one of the early colonists when working the Quebradilla mine 
on the western outskirts of the city. It weighs 907 kilograms.

21. The Toluca Group of Meteoric Irons. —Numerous masses 
of meteoric iron, varying in weight from 300 pounds to minute 
specimens, have been found in the Toluca valley, and it is 
highly probable that they all came from the vicinity of 
Xiquipilco, in the state of Mexico. Many of these masses 
were used by the native blacksmiths for making agricultural
