botanical gardens are enough to warn us that human interference 

 may upset pretty completely for our snails the infinite complex in 

 which they live and move and have their being. 



Much help in the examination of the waters has been gratefully 

 received from E. VV. Bowell, J. A. Boycott, and A. A. Whitaker. 

 The data relating to Pisidium are wholly due to C. Oldham, who has 

 identified all our material ; I know about them only enough to appre- 

 ciate the skill and labour that he has been good enough to spend on 

 them. My thanks are also due to the many naturalists whose obser- 

 vations I have freely used without acknowledgment.
