METEORITES OF NORTH AMERICA. 263 



the entire surface is perfectly uniform. Under a moderately strong magnifying power Kokomo appears as an entirely 

 homogeneous mass, -with the exception of extraordinarily small, strongly reflecting points. At first, by the employ- 

 ment of a magnifying power of about 200 diameters, one sees a succession of dark, faint, and bright, glistening particles; 

 since one can not distinguish a distinct line of demarcation between one and another of them, it is not possible to 

 determine definitely whether the structure is granular or whether the appearance is due to etching pits. I consider 

 the former the more probable. No accessory material of any sort is noticeable. 



After stronger etching the surface of the section becomes dull and finally uneven, owing to the formation of small 

 round pits closely packed together; the ascertainment of the structure is not thereby furthered, however. Analysis 



by Sjostrom gave:

Cohen classed the meteorite as a compact iron with hexahedral streaks, placing it in the 

 same group with the Cape iron, etc. 



Only 655 grams of this iron are recorded in collections. Harvard has the largest amount, 

 418 grams. The whereabouts of the main mass seem to be unknown.

LA CHARCA. 



Near Irapuato, State of Guanajuato, Mexico. 



Here also Irapuato. 



Latitude 20° 53' N., longitude 100° 55' W. 



Stone. Chondrite (C) of Brezina. 



Fell 11.30 a. m., June 11, 1878. 



Weight, 399 grams (14 ozs.). 



Little seems to be known regarding this meteorite. It is merely mentioned by Vom Rath, 1 

 Brezina, 2 and Castillo. 3 Under the name of Irapuato Castillo 3 says that the meteoric stone of 

 Irapuato fell June 11, 1S78, between 11 a. m. and noon. Its weight, he states,' was 399 grams. 

 He says that it has been described by Prof. S. Navia of the College de Guanajuato. Vom Rath ' 

 states that the same college possesses the whole stone. No specimens seem to have reached 

 other collections.

The first account of this meteorite was given by Smith, 1 ' 2 as follows: 



The announcement of the discovery of this iron meteorite was made in a note in the American Journal of Science 

 and Arts. It was discovered in the month of October, I860, by Mr. William Daring, near La Grange, in Oldham County,
