 F. Merrifield, then delivered his Address, in which he discussed some 

 of the causes of the persistent abundance or scarcity, generally or 

 locally, of species and varieties of insects, and the relative importance 

 of the consumption of their food and the attacks of their enemies. 

 Reference was made to striking characters that seemed of no biological 

 importance ; to habits and activities not directly concerned with 

 nutrition or reproduction, and the manner in which they are affected 

 by external conditions ; and to structure and fixed habits indicating 

 their ancestral history and affecting their present capabilities. — H.
