thin twigs that the beaver was able to hold within his teeth; a 
willow twig of this kind is represented in natural size in Fig. 6. 
All heavier branches with a diameter of 40 mm and upwards only 
showed the concave facets. On one only were also found convex 
facets, but under special circumstances; that branch was mainly 
worked upon from one side and very nearly gnawed through, so 
that the two pieces into which it was to be divided were only con- 
nected by a 22 mm broad but rather thin middle part just wide 
enough for the beaver to be able to hold it within his teeth and 
snap it with a few bites. 
The observations, given here, may perhaps on investigating fos- 
siliferous strata contribute towards procuring further evidence about 
the previous presence of the beaver in possible regions.
