The collection of lantern-slides, which is becoming year by year of 

 more importance as illustrations for the courses of lectm'es delivered 

 under the auspices of the Academy, has been increased by the addition 

 of 262 views, the entire collection now numbering 1,243. A new 

 cabinet to hold 1,000 slides has been provided and a card catalogue 

 has been prepared by Dr. Benjamin Sharp. The additions of the year 

 have been derived from the following soiu-ces: Charles Schaeffer, 

 M.D., 25; Benjamin Sharp, M.D., 19; Henry Skinner, M.D., 7; pur- 

 chased, 211. 



A large collection of maps which had accumulated since the founding 

 of the Academy and which was practically inaccessible, have been 

 cleaned, trimmed and backed with linen; 2,128 pieces, forming up- 

 ward of 9,000 square feet, have thus been treated. A case of drawers 

 has been provided for them and they have been roughly classified 

 and placed therein, to be more carefully arranged as soon as time can 

 be found for the w'ork. 



An important part of the journals and periodicals reported has been 

 received in answer to applications for deficiencies written in the course 

 of preparing sets for the binding. Among the more interesting of such 

 acquisitions is a complete set of the Memoirs of the Royal Academy 

 of the Lincei of Rome, efforts to secure which had been made inter- 

 mittently since 1883.
