330 GUERNSEY COUNTY (OHIO) METEORITES. 



examined that fell in Harrison County, Indiana, on the 28th 

 of March, 1859. The latter, however, is the coarser-grained 

 of the two. Prof. Shepard, who is familiar with the meteoric 

 stones preserved in the cabinets of this country and in Europe, 

 says: "In its internal aspect it approaches the stone of Iekat- 

 erinoslaw, Eussia (1825), though it is somewhat finer and more 

 compact. In crust the two are identical. It is also similar to 

 the stone Slobodka, Eussia (August 10, 1818), and compares 

 closely with those of Politz (October 13, 1819), of Nanjemoy, 

 Maryland (February 10, 1828), and of Kuleschowka, Eussia 

 (March 12, 1811); but the crust is less smooth on the Ohio 

 stone than in that of the latter. In fact, its character is that 

 of a large portion of the known meteoric stones." 



The general thickness of the crust is about from one thirtieth 

 to one fourtieth of an inch. 



The cut (fig. 3) is a representation of the largest stone that 

 has been found, now in the cabinet of Marietta College, and 

 described by Prof. E. B. Andrews. We reproduce the figure 

 from Prof. Andrews's article here cited. 



Several specimens have been examined. They all show the 

 presence of the same minerals, with a slight variation in their 

 proportions, as might be expected in a mass not homogeneous. 

 Its composition is fairly represented as follows : Specific gravity,
