THE PREDACEOUS WATER BEETLES, 
In concluding these notes I would urge that none should be deterred 
from the pursuit of knowledge, even amongst the beetles of our ponds 
and streams, by any false notions of distastefulness for the objects to be 
studied. It is our want of knowledge that makes us dislike such things ; 
the more knowledge we obtain respecting them the more interested we 
shall become, and, though we may not see beauty in everything, we 
shall certainly see it in Beetles.*

* It is to be hoped that Mr. Robson will continue to observe the Water 
Beetles of Leicestershire. 
There certainly must be many more species, even of the 
Hydradephaga, to be obtained and reported.—Ebs. M.N.
