DEPARTMENT OF MOLLUSKS. 109 



aimuai and monthly reports of each curator should contain a statement 

 of specimens sent out, in exchange or by donation, or with names, for 

 the assistance of local students. Much of this work is among the im- 

 portant results of the Museum organization and should be put' on record 

 in the reports as such, in order that the Museum may receive due credit 

 for it, and that the public may know that such services are rendered. 



It would also add to the completeness of the exhibit of the activity of 

 the National Museum were such specialists as receive material from 

 the Museum for investigation, or books from the Museum library for 

 use in study, to be called upon to make an annual report, more or less 

 precise, of the kind and amount of material, or the number of books, 

 in their hands, to the Director of the Museum. 



It may be thought that some of these suggestions exceed in their 

 range those limits which might be supposed to hedge in a curatorship. 

 If this be the case, I have only to say that they are inspired by a desire 

 for the utmost efficiency and prosperity of the institution to which I 

 have devoted so much of my time and strength for nearly twenty years, 

 and that, whatever be the decision upon them, I shall cheerfully ac- 

 quiesce in it.
