Societies and the Control of Plant Extermination/’ which gave rise to 
considerable discussion. 
Mr. R. H. Whitehouse, of Belfast, afterwards read a paper on “ The 
Best Means of Preventing the Extinction of Local Species.” After dis¬ 
cussion on this paper, the Chairman submitted the following resolution 
of the Council on the subject in these terms :—“ That the British Associa¬ 
tion for the Advancement of Science deplores the rapid destruction of 
fauna and flora throughout the world, and regards it as an urgent duty 
that steps should be taken by the formation of suitably placed reserves 
or otherwise, to secure the preservation of examples of all species of animals 
and plants irrespective of their economic or sporting value, except in cases 
where it has been clearly proved that the preservation of particular 
organisms, even in restricted numbers or places, is a menace to human 
welfare.” 
This was seconded by Sir Edward Brabrook, and agreed to. The 
Chairman then drew the attention of the Conference to fresh evidence 
which it was desired to gather regarding the working of the Wild Birds’ 
Protection Acts, and suggested that the various societies represented 
ought to be able to furnish valuable information to the Departmental 
Committee, which it was understood would shortly be appointed. 
Cordial thanks were accorded to Mr. Wilson for the report, and for 
having represented the Club as Delegate.
