THE FRANCE VILLE METEORITE 855 



Mr. John M. Davison, to whom was given 23.9 grams for 

 analysis, reports : 



The specific gravity of this siderite is 7.87. A proximate analysis gave : 

 Soluble in hydrochloric acid, kamacite and taenite, 99. 16 per cent.

The weight of this most interesting siderite is forty-one 

 pounds and six and one-half ounces, or 18.3 kilograms. 



Colorado has not been prolific in supplying meteorites to the 

 scientific world. As far as noted, there have been but five, 

 including the present iron, all of which are siderites, viz. : 



Russel Gulch, Gilpin county - - found 1863 



Bear Creek, near Denver - found 1866 



Jefferson, thirty miles from Denver - - fell June, 1867 



Franceville, El Paso county - - found 1890 



Mount Ouray, Chaffee county - - found 1894 



One of these, the "Jefferson (No. 8i,Shepard Collection), 

 thirty miles from Denver, Colo.," listed as having fallen in June, 

 1867, I can find no account of outside of the descriptive cata- 

 logue of the meteorite collection in the United States National 

 Museum, January, 1902. It seems apparent that a mistake has 

 been made in labeling this specimen, and it must be dropped as a 

 distinct fall for the following reasons : 



The Bear Creek meteorite has been noted in most catalogues 



o 



as having been found in Denver county, Colo., which is also a 

 mistake, as Colorado has no county by this name. The Bear 

 Creek meteorite was first mentioned by Shepard 1 as found upon 

 the eastern slope of the Sierra Madre range of the Rocky 

 Mountains, and Henry 2 notes it as found in a deep gulch near
