GENERAL NOTE 77 



down by Mr. Macpherson might give us a clue as to the meaning 

 of the disparity in size between the sexes which this species more 

 than any other displays. The kestrel, peregrine, merlin, and 

 Montagu's harrier still remain to us, in favoured spots, for study on 

 the same lines, and it is to be hoped that before they are added 

 to the long list of departed species their domestic economy will 

 have been added to our records.
