A 48. 
No. I. — A ball of greenstone, found in Ohio. 
No. 2. — Ball of syenite, Ohio. 
No. 3. — Ball of greenstone, Ohio. 
No. 4. — Ball of quartzose rock, Ohio. A stone ball, resem- 
bling the specimens in this case, found in New Mexico, is 
shown in Case A 42, No. 10. Probably, some of these stone 
balls may have served for weapons, wrapped in leather, and 
mounted at the end of a stick. 
No. 5 is a ball of chert, flattened on the under side. It was 
found in Ohio, and is bruised upon the surface like the flint 
balls met with in England, supposed to have served as hammer- 
stones. See No. 3, Case A 20, found at Icklingham ; and 
several examples from Bridlington, in Case A 21. No. 6 is a ball 
of greenstone, with a groove worked around the centre, Ohio.
