G. F. Kunz—Meteorites from Kentucky and Mexico. 235 
The specific gravity of the piece was found to be 7509, the 
analysis by James B. Mackintosh, E.M., of Lehigh University, 
is given below. ‘To this are addéd analyses of masses found 
nearest to Catorze, since G. V. Bogulawski suggests that per- 
haps the Charcas, Zacatecas and Durango irons were all parts 
of one fall.* Charcas.

Del Riot mentions that two of his pupils found above the 
Aqua Blanca Hstate, native iron in a conglomerate rock in a 
vein from one to two fingers in width. Burkart{ says that 
he saw, in the possession of Sefior Chialiva in Zacatecas, a mass 
of meteoric§ iron weighing between ten and twelve pounds 
that was said to have been found in the vicinity of Catorze— 
or rather Alamos de Catorze as it is known—which is in 
San Luis Potosi, about 200 miles southwest of Durango, 40 
miles north of Charcas, and 340 miles north of Toluca. There 
is also in the Museo Nacionale of the City of Mexico a mass| 
weigbing 576 kilos which was found at Descubridora in San 
Luis Potosi; it was described in 1878. 
The well-known Charcas mass, weighing 780 kilos, was 
found in the corner of the church at Chareas, San Luis Potosi, 
Mexico, by some French soldiers and taken by them to Paris 
in 1866. This mass was first mentioned by Sonnenschmid, 4 
and afterwards by Humboldt.** rom all appearances, how- 
ever, | am inclined to believe that the iron now under consid- 
eration is a new and distinct fall.

d Perhaps part of the iron here described, since it showed an old break on one 
side.
