Linton. — Trematode Parasites of Fish 259 



In large bodies of water or in the open sea, the problem 

 becomes a more difficult one. And yet, even in such places, 

 it is not incredible that some check is possible for these forms 

 of parasitism. 



There has been and is much laudable zeal displayed in 

 the enactment of laws for the protection of birds. I hope 

 that I shall not be misunderstood when I suggest that this 

 zeal might be allowed to suffer some abatement, especially 

 with respect to fish-eating birds. Surely the fish are deserv- 

 ing of some consideration as well as the birds, and man's 

 comfort and well-being are still of vital interest and im- 

 portance.
