district should be made out. I am glad to say that a good 
beginning has been made, and besides older lists appearing 
in our ‘ Transactions,’ there have been recently much 
amplified lists of Entomostraca, Coleoptera, Rotifera, and 
Hydrachnida. 
Besides lists of species, it is necessary to be acquainted 
with the physical and chemical characteristics of each separate 
sheet of water, the nature of the bottom deposits, and so on. 
I think the Broads offer peculiar opportunities for the 
study of individual species, their anatomy, physiology, and 
their relations to their environment and to each other. 
We have already had papers read before us and published 
in' our ‘ Transactions ’ dealing with bionomics by statistical 
methods, and I hope not only that this work will be continued, 
but that other workers may be found to take up different 
branches of Limnobiology and work at the same problems 
by different methods, and I should be very pleased if I could 
think that I have, by these few remarks, put before you 
to-night, persuaded any member that the study of fresh- 
waters is a fascinating one and worth spending time over. 
I may add that I hope to get together a museum collection 
at Sutton illustrative of Limnobiology, 1 and if any member 
can assist by procuring specimens, I am sure that Mr. Balfour 
Browne, who is in charge of the Laboratory, will be very 
glad of his help.
