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 Dixon, 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.
