Recent Researches among some of the more simple 

 Sarcode Organisms. 



[Eead May 24, 1877.] 

 (Second Notice.) 

 In my last year's Address I attempted au exposition of researches 

 among certain lower sarcode organisms to wliicli within the last 

 few years the attention of zoologists had been directed. The 

 subject, however, proved to be so large, and the activity which had 

 prevailed in it so great, that I found it impossible to do justice to 

 it within the limits of a single address. I was therefore compelled 

 to leave untouched much of what was necessary for a complete 

 exposition, and I purpose on the present occasion to take up the 

 subject where I was then obliged to leave it.
