1870.] 307 [Annual Report. 



Annual Meeting, May 4, 1870. 



Dr. C. T. Jackson in the chair. Seventy three members 



present. 



Mr. S. H. Scudder presented the following Report of the 

 Custodian for the past year : — 



In presenting, to-night, my final report of the annual oper- 

 ations of the Society, I trust the members will pardon an 

 occasional review of the experience of past years ; such re- 

 marks will be brief and simply offered to show what progress 

 has been already made and what lessons can be drawn for 

 future guidance. As it is evident that in many minds our 

 present system is an experimental one, any considerations 

 which may help to solve the problems of the Society's daily 

 life will be worthy of attention. 



During the year that has just closed there have been 

 eighteen general meetings of the Society, eight of the sec- 

 tion of entomology, and seven of that of microscopy. At 

 the general assemblies, the average attendance has been 

 thirty two, at those of the entomological section eleven, and 

 at the microscopical meetings nine. Forty seven scientific 

 communications, made at these meetings by twenty five per- 

 sons, have been printed in full or by title in our Proceedings, 

 viz., thirty one papers by fifteen persons at the general 

 meetings; twelve papers by nine persons at the meetings 

 of the entomological section, and four papers by as many 

 persons at those of the section of microscopy. The follow- 

 ing are their titles : —
