- Curator's comments
- Register 1955:
No. 15: Metal alley ball, hollow and with internal bar, possibly originally a bolas weight.
No. 16: Similar [to Am1955,08.15].
No. 17: Similar [to Am1955,08.15], crosses cut and filled with a black material.
From modern Indians in the highlands of Perú.
15-17 [Am1955,08.15-17]: Spectrographic analysis shows that they were made of copper, tin, iron, silver. They seem to have been cast in one piece. The inlay of 17 [Am1955,08.17] shows copper, tin, manganese, iron, silver, phosphorus - under the microscope it consisted of a granular bronze mixed with some black material, which was non-inflammable and insoluble in acids. The sample was too small to identify it. See Correspondence, 1955, s.v. Planderleith. (H.J.Pl).
