REPORT OF NATIONAL, MUSEUM, 1924 121 



and Mrs. J. L. Grimwood, Brooklyn, N. Y. This is a camera in 

 which 12 plates could be exposed in rapid succession by turning a 

 crank. It was entirely different in principle from the "battery of 

 cameras " invented and used by Muybridge. In his case the ex- 

 posure was made by the person or animal being photographed com- 

 ing in contact with strings which were attached to each camera. In 

 the Levison machine the exposure was governed by the operator, all 

 plates being exposed through one lens and from the same identical 

 spot. This machine was described in several newspapers of 1887 

 and application for patent was made June 26, 1888, but was allowed 

 to lapse. This is one of the first, if not the first, motion-picture 

 camera made to expose successive plates from one spot and was 

 adaptable to the use of film. Proof of its early existence, and plates 

 and prints made in 1887, accompanied the gift. 



From Miss Frances Benjamin Johnston of New York came com- 

 plete sets of Camera Work and Camera Notes. These are very rare. 



The pictorial section received many notable additions, of which 

 the following are important: Two very attractive prints from the 

 veteran child photographer E. B. Core, New York City; Dr. T. W. 

 Kilmer, New York, four multiple-gum prints which had been exhib- 

 ited at several salons ; and Dr. J. B. Pardoe, Bound Brook, N. J., In 

 the Doorway, one of his very attractive productions. Three specimens 

 of the new printing process, " Resinopigmentipia," were received 

 from Joseph Petrocelli, Brooklyn, N. Y. This is a dry-pigment 

 process which produces very beautiful results. H. A. Latimer, Bos- 

 ton, Mass., added six multiple-gum prints to his already generous 

 contributions. 



Floyd Vail, New York City, added one more of his beautiful 

 prints, which makes seven now owned by the Museum. His son, 

 Floyd Eugene Vail, gave two bromoils and a portrait of his father ; 

 his work is of high pictorial and technical quality. 



The international character of the pictorial section was strength- 

 ened by eight prints from E. O. Hoppe, London, England, and three 

 from Christopher James Symes, Birkenhead, England, all of which 

 are of high artistic quality. Our pictorial section now contains 

 representative examples of many of the famous pictorial photogra- 

 phers of the world. 



Notable assistance has been rendered by the following persons: 

 Frank V. Chambers, of Philadelphia, editor of The Camera, has 

 given much publicity to the photographic collections and through 

 notices of the needs of the exhibition series, valuable exhibits have
