The following annual reports were ordered to be printed: 



REPORT OF THE RECORDING SECRETARY. 



While the Recording Secretary has been able personally to dis- 

 charge the duties of his office during the year, he is indebted to the 

 Assistant Librarian, William J. Fox, for indispensable cooperation, 

 for which grateful acknowledgment is due. As was the case last 

 year, the statistics of administration have been prepared by Mr. Fox. 



Dr. J. Percy Moore and Dr. Philip P. Calvert have placed the 

 Secretary under obligation by acting as Recording Secretary during 

 the earlier meetings of the Academy and the Council, for which 

 sincere thanks are given. The By-Laws provide for the closing of 

 the academic year with the last of November. Since that period 

 last year meetings have been held on December 18, 1917; January 

 15th, February 19th, March 19th. April 9th, April 16th and Novem- 

 ber 16th of the current year. 



The meeting of April 9th was held in commemoration of the Presi- 

 dent, Samuel Gibson DLxon, M.D., LL.D., Sc.D., who died February 2d. 

 Dr. Dixon had been elected a member of the Academy February 25, 

 1890. He had served as President since 1896. The progress of the 

 society during the twenty-two years which have since elapsed is 

 Dr. Dixon's best memorial. Details of his services to science will 

 be found in the proceedings of the memorial meeting held in April. 

 As a mark of respect to the memory of Dr. Dixon the election of 

 his successor in the presidency was by resolution postponed until the 

 annual meeting. 



Communications were made at the meetings during the year by 

 Messrs. Harley Stamp, Philip P. Calvert, James A. G. Rehn, Witmer 

 Stone, Edwin G. Conklin, John Cadwalader, Benjamin F. Royer 

 and Henry Skinner. 



In addition to the Proceedings of the Dixon Memorial Meeting 

 papers were presented for publication by Henry A. Pilsbry, F. J. 

 Keeley, Henry W. Fowler, Anna M. Cullen, Janet P. Jameson, 

 Mitchell Carroll, Joseph Hall Bodine, Bruce Wade, James A. G. 

 Rehn and E. G. Vanatta. 



The sixteenth volume of the Journal was completed by the 

 publication of a beautifully illustrated paper by Clarence B. Moore 

 on the aboriginal antiquities of Florida.
