METEORITES OF NORTH AMERICA. 261 



Leick 5 found that plates of the iron were capable of taking and retaining magnetism from 

 an electromagnet. 



Taenite from the meteorite was described by Farrington 6 as follows : 



One of the sections of the Kenton County, Kentucky, meteorite in the Field Museum collection tends to decom- 

 pose along the planes of structure marked by the Widmanstiitten figures. The result of this decomposition is a sepa- 

 ration of the mass into fragments bounded by octahedral planes, of a homogeneous alloy of iron-gray color between 

 which lie thin, elastic plates of a tin-white color. The first alloy is undoubtedly kamacite, the second tsenite. In 

 order to compare this tsenite with that known from other meteorites, some study of it was made. The fragments which 

 it was possible to separate rarely exceeded 4 sq. mm. in surface. As plates, they were thin, elastic, and magnetic. 

 The only feature noted regarding their surface was that it is often marked by parallel rows of minute ridges extending 

 across the plate. Corresponding striations usually appear on the adjacent kamacite. The plates are soluble in copper 

 ammonium chloride, and fusible with difficulty B. B. 



In separating plates for analysis care was taken to use only those which could be completely isolated and 

 showed no rust. This proved a laborious operation, and after considerable toil the amount that could be secured for 

 analysis was only 0.022 gram. The analysis was made by Mr. H. W. Nichols. Iron was determined by titration with 

 an n/100 potassium bichromate solution, and cobalt and nickel isolated by means of two ammonia and three basic 

 acetate separations and then precipitated electrolytically. 



While the extremely small amount used for analysis makes the chances of error larger than is desirable, it is 

 believed that fairly accurate results were attained. 



The analysis gave: 



Fe 80. 3 



Ni and Co 19. 6 



99.9 

 The iron is distributed, the Field Museum possessing about one- third.

The first description of this meteorite was given in the American Journal of Science, 1 as 

 follows : 



At a meeting of the Indianapolis Academy of Sciences, November 20, 1872, Prof. E. T. Cox presented a paper on 

 a hitherto undescribed meteorite, which was found in the year 1870, in digging a well on Mr. Freeman's farm, 7 miles 

 southeast of Kokomo, in Howard County, Indiana, by Doctor Saville, who now lives in Sioux City, Iowa; and we are 

 indebted to him for its preservation. It was presented to Prof. John Collett by the doctor last August, when he visited 

 Sioux City, and it has been loaned to Professor Cox for examination and description. 



The depth at which it was found in the well could not be satisfactorily learned; but from being embedded in 

 plastic clay, which lies beneath a bed of peat, the probability is that, in falling, it met with no very great resistance 

 until it reached this clay. It is a flattened, irregularly shaped mass, rounded on one side and concave on the other; 

 the surface is darkened and covered with slight indentations. The dimensions are: Greatest length, 5 inches; average 

 width, 3.5 inches; average thickness, 1.7 inches; its weight is 4 pounds 1.5 ounces, avoirdupois. A small piece has
