these curves, it must be apparent from the consideration of them that there 

 is a necessity for unremitting activity to increase the membership, and that 

 this activity should be directed on the one liand to those classes of persons, 

 such as physicians, teachers, and others, from whom we can reasonably 

 expect a greater interest and greater appreciation of the work which the 

 Academy is attempting to do, in order that the persistence of their member- 

 ship may be as long as possible. It is clear also that the Academy derives 

 its principal resources from those persons who have been members only a 

 comparatively short time and it will in all probability continue to do so; 

 hence the desirability, indeed the necessity, on the other hand of inducing 

 persons to join the Academy who, though not actively engaged in scientific 

 work, appreciate its purposes and aims and are willing to help others to do 

 the work, even if they persist for only a comparatively short time. 



All honor, then, to that small body of scientific workers who have kept the 

 Academy alive through many ups and downs ; all honor too to that larger body 

 of science-lovers who have provided the Academy, and we hope will con- 

 tinue to provide it in larger measure, with the wherewithal for doing its 

 work.
