_ mineral, or peculiarity of base. A fourth form, and a very common 
one, is that given in the five illustrations (Figs. 
35, 36, 37, 38, 39). In these examples we see 
the one common character of an unnotched 
base, and that the blade of the arrow is consid- 
erably wider, the width increasing abruptly in 
three specimens and less so in the other two. 
The specimen (Fig. 35) is of jasper, beautifully 
wrought, and very accurately bevelled from the 
centre to the edges, which are smooth. The 
length, one inch and three-quarters, decides its 
use, that of an arrowhead only. The speci- 
men that approaches this most nearly is that 
iven in Fig. 39. This is Fig. 43.

well made, considering the material, and if 
used as an arrowpoint must have required a 
very heavy shaft and powerful bow. A series 
of specimens, figured by Prof. Nilsson as 
coming from Mexico, Ireland, and Terra del 
Fuego, and all bearing considerable resem- 
"lance to the illustration we have given, are 
Called, one an “arrowhead,” another a ‘‘har- 
Poonpoint.” We will leave it to be decided 
in future, if it can be, to which class this
