REPORTS OF MEETINGS. 



Monday evening, February 25. Joint meeting of Sections B 

 and D, the President of Section D in the chair; Mr. Edgar D. 

 Cass Secretary pro tern. 



This being the last joint meeting for the season of Sections B 

 and D, a review of the biological work undertaken during the 

 fall and winter was presented by Mr. E. J. Burnham, who traced 

 the development of the brain from the simple notochord of the 

 lancelets progressively upward to the extremely complex organ 

 possessed by the highest vertebrates. 



At the close of the review a vote of thanks was extended to 

 the speaker for his able and generous assistance in maintaining 

 the interest of the joint meetings. 



Adjourned to March 20. 



Wednesday evening, March 20. Regular meeting ; the Vice 

 President in the chair ; Miss Mary F. Dana Secretary pro tern. 



Mr. E. H. Fogg, for the Executive Committee, reported a 

 plan of work for the ensuing season. This was to consist of 

 lectures, papers and readings on topics of interest to the Section. 

 The report was accepted. 



By request. Miss Dana read for the second time her paper on 

 '■ The Theory of the Migration of Birds." This was followed 

 by a discussion. An article in Bird Lore by Mr. William 

 Brewster, on " A Study of a Ivincoln's Sparrow," was read. 

 Members of the Section were urged to look carefully for this 

 species, since it doubtless passes through the Merrimack valley 

 in the migrations.
