ON BRISTOL EOTIFEES. 161 



In conclusion, I have only to add that, although Ikistol has but 

 few ponds, and (so far as I know) not a single clear slow stream, 

 yet there is ample scope (as I think I have shown by the above 

 sketch) for anyone who wishes to delight and instruct himself 

 by the study of these beautiful living atoms.
