Annual Meeting.] 194 [May 2, 



part of Prof. Hyatt's " Revision of North American Porif- 

 era3 " is in press, and will be published during the month. 



MEETINGS. 



The attendance at the general meetings has been good, 

 and the interest of the communications presented well sus- 

 tained. The meetings of the Section of Microscopy, whose 

 place has been taken by the new Boston Microscopical Soci- 

 ety, have been given up. The Section of Entomology holds 

 its meetings as usual, with a small but regular attendance. 



Since the last Annual Meeting a new Section, devoted to 

 Botany, has been formed, holding bi-monthly meetings 

 which, on the whole, have been fairly attended. 



During the year four Corresponding Members, six Resi- 

 dent, under the old Constitution, and twenty-five Associate 

 Members under the new, have been elected. 



LOWELL LECTURES. 



Five courses of free Lectures, supported by John A. 

 Lowell, Esq., trustee of the Lowell Institute, have been 

 given during the season, viz. : six on Comparative Embryol- 

 ogy, by Mr. Charles S. Minot ; four on North American 

 Archaeology and Ethnology, by Mr. F. W. Putnam ; three 

 by Major J. W. Powell, on the Canons of the Colorado, In- 

 dian Life in the Rocky Mts., and Indian Mythology ; six by 

 Prof. N". S. Shaler, on the Geological Problems of Boston 

 and Vicinity, and, lastly, five by Mr. S. H. Scudder, on the 

 Organization and Metamorphoses of Butterflies. The courses 

 seem to have been unusually interesting and well attended. 

 Major Powell's Lectures had the largest attendance, aver- 

 aging about two hundred.
