Grange, from the following localities: First, the ancient ruins of 
Tiahuanaco near Lake Titicaca, north of the high Bolivian plateau; 
second, from very old cemeteries which have been explored, in the 
vicinity of Yura, between Uyuni and Potosi; third, from the Re- 
public of Ecuador; and fourth from several localities north of the 
Argentine Republic, between Salta and the Bolivian frontier. In a 
second series (Nos. 27 to 48) have been grouped twenty-four analyses 
taken from the interesting work of Juan B. Ambrosetti upon bronze 
in the Calchaqui region. These analyses were made by Messrs. Juan 
J. J. Kyle, chemist of the mint of Buenos Aires, Eduardo Suarez, 
and Herrero Ducloux. They relate entirely to objects discovered in 
the valleys along the eastern side of the Cordillera, northwest of the 
Argentine Republic (provinces of San Juan, of La Rioja, of Cata- 
marca, of Salta, and of Jujuy).
