and Secretary, who for the past fourteen months has been engaged 

 upon it, together with work connected with the Museum. While 

 much remains to be done, it has yet reached the condition when 

 every volume, pamphlet or document is so arranged and cata- 

 logued as to be readily found when needed. This work we hope to 

 have prosecuted ; and thus will our comparatively small collection, 

 thoroughly indexed, prove, for scientific aid, of more value than a 

 larger one not so carefully classified. Were we able to resume the 

 publication of our Transactions, our Library, and, indeed, our Mu- 

 seum also, would receive large and valuable accessions, both by 

 donations and exchange. In several departments of science we 

 could furnish material for such publications had we the means to 

 expend.
