BOSTON SOCIETY OF NATURAL HISTORY. 229 



Corresponding or Honorary. Five Associate or Corporate members had resigned, and 

 four had died. The whole number of Associate and Corporate members was stated to be 

 451. 



There had been an average attendance of thirty-nine persons at the sixteen general 

 meetings of the Society. The largest number present at any one time was eighty-one, 

 the smallest nineteen. Eight meetings of the section of Entomology had been held, the 

 average attendance at which had been eight persons. The meetings of the botanical 

 section had been given up in consequence of the non-attendance of a sufficient number of 

 members to render them interesting. 



In December of the past year, by consent of the Society, the section of Microscopy was 

 revived, and monthly meetings had since been held, though without a very promising 

 attendance. 



Of the library, the Secretary stated that the additions to it during the year exceeded 

 those of any other in the Society's history. These were summarized thus : 



8vo. 4to. Fo. Totals. 



Volumes 348 69 2 419 



Parts of Volumes 947 156 170 1273 



Pamphlets 335 52 2 389 



Maps and Charts . 99 



In all 2180 



Besides the constant use made of the books by members and others at the Library, 

 there had been borrowed' 1110 volumes during the year, by one hundred and twenty- 

 three persons. 



Of the publications two parts of the twentieth volume of the Proceedings, and a third 

 article for the third volume of the Memoirs had been issued, the last being a revision of 

 the Palaeozoic Cockroaches of the world, by Mr. Samuel H. Scudder, 113 pages, 5 plates. 

 Of " Occasional Papers " a volume had been published, being the third of the series, con- 

 taining Mr. W. 0. Crosby's contributions to the Geology of Eastern Massachusetts, 266 

 pages, with 5 plates and a colored map. 



In addition to these, No. 6 of the series of Guides for Science Teaching, by Professor 

 Hyatt, had been printed, also a pamphlet introductory to the general guide to the Mu- 

 seum, also by Professor Hyatt. Copies of this last publication were presented to the 

 audience at the celebration of the semi-centennial anniversary of the Society. 



The Committee on Publications having suggested that a special volume should be pub- 

 lished commemorative of the fiftieth anniversary of the Society, the Council voted that 

 this should be done provided a sufficient number of subscribers could be obtained for such 

 volume at the rate of ten dollars a copy, to justify the necessary expenditure. To ensure 

 the success of this project the Rev. Robert C. Waterston, with characteristic generosity, 

 had already given one hundred dollars. It was understood that the volume should contain 

 a history of the Society, and a series of scientific papers, and be entitled "Anniversary 

 Memoirs of the Boston Society of Natural History." 



Walker Prizes. Relative to the Walker Prizes, the Secretary stated that no essay had 

 been presented on the subject proposed for 1880, viz. : 



" The evidences of the extension of the Tertiary deposits seaward along the coast ol 

 Massachusetts."
