THE MEXICAN METEORITES.

latter location the maximum dispersion, according to present 
indications, was not over sixty-six miles. 
The principal object of the paper which I present this 
evening is to bring together in as compact form as possible 
the latest and most complete information in regard to the 
Mexican meteorites and to place the data in convenient form 
for reference. 
Much of the data here presented will correct and supple¬ 
ment some of the tabular matter in regard to Mexican me¬ 
teorites that occurs in a former paper by the present writer 
and read before the Philosophical Society April 12, 1890.* 
The results of the investigations in the two papers already 
referred to have been freely used, as well as information from 
other sources, while no small amount of time has been be¬ 
stowed upon my own investigations. The paper by Fletcher 
contains copious references to the bibliography of the sub¬ 
ject, rendering such references in this paper quite unneces¬ 
sary. 
The actually observed falls of meteorites in Mexico have 
been very few. The following list is believed to contain all 
that have been well observed: 
1. November 24, | is04 J ■^■ ac ^ en( ^ a Bocas, state of San Luis Potosi. 
% 
2. January, 1844, at Loma de la Cosina, state of Guanajuato. 1.2 
3. June, 1865, at Hacienda d’Avilez, state of Durango. 
4. June 11, 1878, at Irapuato, state of Guanajuato. 0.40 
5. September 17,1879, state of Jalisco. 
6. June 18,1881, at Pacula, state of Hidalgo. 3.36 
7. November 27,1885, at Mazapil, state of Zacatecas. 3.95 
Number 7 of the above list is an iron meteorite and fell 
during the meteoric shower of November 27,1885. It is the 
only recorded fall of an iron meteorite during a periodic 
shower, but it is not likely that it had any connection what¬ 
ever with the small bodies producing the shower of Novem¬ 
ber 27. The first six numbers on the list are stony meteorites.
