and on the whole it resembles them considerably. Published analy- 

 ses of Toluca irons give percentages varying somewhat widely, within 

 which limits the Los Reyes values may certainly be included. For 

 purposes of comparison of analyses, several that have been made of 

 Toluca irons by different authorities are given below:

The resemblance in chemical composition to the average of To- 

 luca irons is thus seen to be close. Further, the etching figures come 

 within the limits found in Toluca irons, since these vary considerably 

 in detail as is well known. The meteorite will be designated, there- 

 fore, as Toluca (Los Reyes). 



HOPEWELL MOUNDS, ROSS COUNTY, OHIO. 



MUSEUM No. Me. 480. 



Among the objects obtained from the Hopewell Mounds of 

 Ohio, and now in the Anthropological collections of this Museum, 

 are a number made of iron. These include a part of a head 

 and ear ornament, some celts, a number of beads, and lastly a 

 small unwrought mass weighing about 130 grams (5 ounces). 

 Dr. G. A. Dorsey, to whom I am indebted for calling my 

 attention to them, informs me that they were all found 

 associated with a single human skeleton near an altar of one of 

 the mounds. They were considerably oxidized, so that the original 

 metal is in most cases obliterated, but the unwrought mass above 

 mentioned was found to be oxidized only on the surface. A quali-
