66 REPORT 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 by 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 Observatory, 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 nebulx, 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 stereomotorgraph, 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 pottery, 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
