the stomachs were examined whiU^. fresli ; a small nnml)er were pre- 

 served in formalin for a few weeks before examination. 



In making the examinations the stomachs were split along the 

 outer cnrvatnre and the contents washed into a glass dish. The 

 material thus obtained was separated into groups and the insects or 

 parts of insects and other animals were identified by comparison with 

 named specimens. The relative per cent by bulk of each class of 

 food was then estimated and the data as to character and amount 

 were noted.

The contents of the stomachs examined may be readily separated 



into three groups, animal, mineral and vegetable, but the presence 



of substances other than of an animal nature is probably more or less 



accidental. 



Vegetahle Matter. Of the total contents of one hundred and 

 forty-nine stomachs, vegetable material formed less than one per cent 

 and from its character appears to have been taken by accident and 

 cannot be properly considered as food. .Since the toad takes the 

 greater part of its food from the ground by means of its large, fleshy 

 tongue, nothing can be more natural than that a small quantity of 

 vegetable detritus should be swept into the mouth along with the 

 insects on which the animal fesds. The miist common vegetable
