For my knowledge of the meteoric iron of El Dorado Co, 
I am indebted to Mr. Alfred Stebbins, librarian of the Merean- 
tile Library Association of San Francisco. A letter from him, 
dated April 26th, inclosed a few grams of turnings obtained dur 
ing the separation of a slice of the mass destined for the collee- 
tion of the geological survey now in progress under the direc- 
tion of Prof. Whitne 
The mass is dcmaabea by Mr. Stebbins as having the size and we 
shape of a man’s head. It was found in a field, and, as usual, 
was first taken to a blacksmith’s shop, where it was soon found :
