9. A mass of meteoric iron was shown among the Mexican 
minerals at the United States Centennial Exhibition, in 
Philadelphia, in 1876, and afterwards brought to its present 
resting place in the National Museum, in Washington. 
The maximum dimensions of the mass are 37.5 X 24.5 X 17 
inches. So far as known, it has never been weighed, but it 
will probably weigh about 1,134 kilograms. The locality 
whence it came is entirely unknown, but I think it highly 
probable that it is the Casas Grandes mass. 
10. Cornejo, in 1869-70, and Barcena, in 1876, mention 
the occurrence of meteoric irons in the vicinity of Presidio 
del Principe, in the state of Chihuahua, but nothing definite 
is known about them. 
11. The Huejuquilla group of meteorites was originally 
known as the “ Durango iron,” on account of Humboldt’s 
erroneous supposition that one of the masses which he de¬ 
scribed was found near the city of Durango. Originally 
there were reckoned seven of these masses: 
(1.) Now at the hacienda of San Gregorio; estimated weight, 
11,560 kilograms ; 
(2.) Now at the hacienda of Concepcion; estimated weight, 
3,130 kilograms; 
(3 and 4.) Now at the hacienda of Chupaderos; estimated 
weight, 15,600 and 9,290 kilograms; 
(5.) A small fragment brought from Sierra Blanca ; 
(6.) A small fragment brought from the rancho of Tule; 
(7.) A large mass said to have been seen many years ago 
at Rio Florido, but nothing known of it now. Although 
Weidner reports to Burkart in 1870 that “ during a journey 
to Chihuahua I saw two masses, one at the hacienda la 
Florida, the other at the hacienda Concepcion. Without 
delaying the caravan, I was able to hammer off a small piece 
of the former meteorite,” etc., etc., and in 1866 reported to 
Castillo that the Florido mass was about half the size of the 
Concepcion mass, it is quite probable from Fletcher’s investi¬ 
gations that the two descriptions refer to the same mass.
