 Hence the necessity for conferences between the Secretaries of 

 Societies such as this, so that schedules of questions to be 

 answered may be prepared, and forms drawn up for the tabulation 

 of results, and opportunities be afforded for the discussion of 

 methods and research. Hence the advantage by these Unions of 

 Natural History Societies, under a limited number of which I 

 hope soon to see ranked all the Field Clubs of the land.
