This skull belongs to the Philadelphia Museum, and was lent me by Mr. T. 

 R. Peale. The entire desiccated body was obtained from the borders of the 

 desert of Atacama, not far from Arica. The remains were those of a woman 

 who may have reached her thirtieth year. The hair was very long, and had lost 

 none of its natural black color. With the body was found a small bag, not unhke 

 a modern reticule, in which were contained some copper fish-hooks and small 

 instruments of bone which were probably used in forming the meshes of their 

 nets or other fabrics. Among the envelopes were also observed small pieces of an 

 aromatic gum. 



Through the kindness of Alexander Naysmith, Esq., of London, I possess 

 casts of the six skulls brought by Mr. Pentland from the vicinity of the lake 

 Titicaca, and five of them are strikingly like the specimen here figured, both as 

 respects their general form, their narrow face, their small size, and their several 

 diameters ; yet they present more obvious marks of artificial modification.
