Notes on Copper Implements of America.

The article presents discussion concerning the research article "Mexican Copper Tools and the use of Copper by the Mexicans before the Conquest," by Dr. Valentini and translated by Stephen Salisbury, Jr. as originally printed in the April 1879 issue. Additional commentary is provided criticizing the report's treatment of the archaeological evidence concerning weapons and tools of Mexico in comparison to other cultures in the Bronze and Iron Ages, such as the proto-Etruscan civilization of Italy..
