Graphic arts. — The 51 accessions, 4 more than last 3^car, totaled 1,433 

 specimens, of which the gifts, purchases, transfers, and deposits made 

 a permanent addition to the collections of 482 specimens. The most 

 important accession was 200 old etchings collected by J. Kay, 

 London, in 1826. The lot contains prints by such famous artists as 

 Rembrandt, Claude, Hollar, Cornelius, Bego, and Castiglione, and 

 many by lesser artists, quite a few of which are of much better 

 (jualit}' than those by the more famous etchers. Etchings and dry- 

 points by American artists were received from Joseph C. Claghorn, 

 Mrs. Sybilla M. Vv^eber, and Robert Lawson. 



In connection with the new installation of the photomechanical

 Photographs of the inventors Frederic E. Ives, Max Lev}'', Louis 

 E. Levy, and Karl Kletsch; 3G prints made by the Photogravure 

 and Color Co., of New York, from 3 old photomechanical plates 

 etched about 1860 by Fox Talbot. The Meriden Gravure Co. gave

 prints made by her late husband, Joseph Petrocelli, between 1921 

 and 1928. They are all suitably and effectively framed, and were 

 presented in the hope that they would stimulate a desire to carr^' 

 on this type of work, of which Mr. Petrocelli was a master. 



An important addition to the motion-picture exhibit was a com- 

 plete early Edison projection Idnetoscope acquired from John P. 

 Daniels, Crisfield, Md.
