66 KEPORT OF NATIONAL MUSEUM_, 1914. 



Muybridge arrangement for photographing men and animals in mo- 

 tion, with several prints ; and a complete series of the motion-picture 

 cameras and projectors invented bj^ Mr. C. Francis Jenkins, of 

 Washington. 



The use of photography in connection with scientific observation 

 is represented by the following series of prints, those from institu- 

 tions having been received as gifts: The apparatus and photo- 

 graphic work of the Harvard College Observator}^, in which the 

 views of the stellar spectra and also the very early results are espe- 

 cially notable ; a large photograph of the moon and one of the solar 

 spectrum by Rutherfurd in 1865, a part of the 36-foot solar spectrum 

 by Rowland in 1888, and a series of recent views of the moon by 

 Ritchey; a fine series of illustrations of work done by the Mount 

 Wilson (Cal.) Solar Observatory of the Carnegie Institution of 

 Washington between 1907 and 1911, including a direct photograph 

 of the sun, a calcium spectroheliogram, two hydrogen spectrohelio- 

 grams, pictures of various nebulae, prominences on the sun, star 

 clusters, Halley's comet, Saturn, and Mars, and views of the build- 

 ings and of the various telescopes and other instruments of the ob- 

 servatory ; some very remarkable photomicrographs of disease germs, 

 of laboratory experiments in the growth of animal tissues after the 

 death of the animal, of the transplanting of arteries, etc., from the 

 Rockefeller Institute for Medical Research; and a series of X-ray 

 photographs, mostly of surgical cases, photomicrographs of disease 

 germs causing malaria, cholera, tetanus, hay fever, etc., and of other 

 parasites. 



Under color prints are displayed a few of the various processes 

 resorted to in artificially producing colors, as well as the genuine 

 color photographs, but the representation is very incomplete, and 

 important additions are soon expected. Some of the noteworthy 

 contents of the case are a photographic reproduction in color by 

 Mr. Miley of an old family portrait; several prints by the Mac- 

 Donough-Joly ruled screen process, 1894; one of the earliest three- 

 color colotypes; several of R. W. Wood's diffraction grating color 

 photographs, 1899; one of Prof. Gabriel Lippman's direct color 

 photographs by the interference method, 1891; and a number of 

 autochromes, 1907. A stereomotorgrajDh, with a series of direct color 

 slides, is about to be installed. 



CERAMICS, METAL AND GLASS WARE, ETC. 



The gallery of the northeast court has for a long period been dedi- 

 cated to the subject of potter}^, and for 25 years it contained the re- 

 markable Chinese collection of Mr. Alfred E. Hippisley, recently 

 reclaimed by the owner. In the lack of space for the proper display 

 of certain other classes of art this gallery has also been used for
