it is thought that the petrographs afford additional testimony. Where these viciiua-like animals 

 are delineated ou the ancient rock-caivings, they are often associated with the figure of a man 

 holding in his hand a pecuUar four-branched instrument ; one of the branches is held by its extremity 

 in the liaud, the others are in the air (Figs. 17, 18, and 19). This is thought to depict a herdsman 

 or hunter in the act of casting the holas. The bolas have, as far as can be ascertained, not been

 the Peruvian. 



4. In addition to these indications we must consider the great and closely corresponding 

 prevalence of the os Inew in the skulls of these two widely separated peoples. This is a subject 

 discussed more fully in the somatological part of this work.
