1889.] NATURAL SCIENCES OF PHILADELPHIA. 423 



The following annual reports were read and referred to the Pub- 

 lication Committee: — 



REPORT OF THE RECORDING SECRETARY. 



The Recording Secretary respectfully reports that the meetings 

 of the Academy during the greater part of the year have been un- 

 usually well attended and that the communications have been varied 

 and interesting. The improvement is due in great measure to the 

 plan of joint meetings of the several Sections with the Academy 

 which was first carried into operation in March. A programme of 

 the meetings was issued to the members with the effect of materially 

 increasing the attendance. While communications from members 

 of the Section to which the night is assigned have precedence, they 

 do not exclude those from other members of the Academy and 

 while there have been few meetings without some matter of special 

 interest no difficulty has been experienced in affording opportunity 

 to all who wish to obtain a hearing. Verbal communications have 

 been made by Messrs. Leidy, McCook, Meehan, Ryder, Heilprin,Ives, 

 Binder, Morris, Wingate, Goldsmith, Pilsbry, Foote, Koenig, Perot, 

 Horn, J. B. Brinton, Rex, Hall, Woolman, Wilson, A. H. Smith, 

 Hartzell, Willcox, Redfield, Dolley, Rothrock, Ford, U. C. Smith 

 Campbell, Sharp, Jefferis, Skinner, Baker, Thomas, D. G. Brinton, 

 Leffmau and Aaron. 



Two hundred and twenty-eight pages of the Proceedings for 1888 

 and three hundred and thirty-six for 1889 have been issued since 

 the last report. The current volume will be illustrated by thirteen 

 plates. In connection with the Academy's regular publications 

 mention should also be made of the Manual of Conchology which, 

 since the death of Mr. Geo. W. Tryon Jr., in Feb. 1888, has become 

 the property of the Conchological Section and has been promptly 

 issued in two series under the editorship of Mr. H. A. Pilsbry. Of 

 the Marine Series three hundred and twenty pages of text and 

 seventy-five colored plates, and of the series devoted to Land Mol- 

 lusca two hundred and seventy-nine pages and seventy plates have 

 been issued during the year. It is gratifying to know that the high 

 standard established for the work by Mr. Tryon has been main- 

 tained and that the subscription list is sufficient to more than pay 

 the expense of issuing the work.
