88 REPORT OF NATIONAL MUSEUM, 1914. 
Graphic arts —The more important contributions were as follows, 
namely: Materials demonstrating the process of making three-color 
half-tone plates, from the Zeese-Wilkinson Co., of New York; an 
exhibit containing half-tone screens from 50 to 400 lines to the inch, 
and a circular screen for color work, from Mr. Max Levy, of Phila- 
delphia, Pa.; a Bruce type-casting machine and a hand mold repre- 
senting the early methods of type casting, from the American Type 
Founders Co., of Jersey City, N. J.; examples of rotary intaglio 
printing, the first made in this country, as well as later develop- 
ments of the American patents, from Mr. Charles W. Saalburg, of 
New York; a collection illustrating the process of and the materials 
used in the manufacture of printing ink, from Philp Ruxton, 
of St. Paul, Minn.; an autochrome plate with progressive proofs of 
the same made by the Colorplate Engraving Co., from Dr. Ulysses 
S. Kahn, of New York; and 91 engraved bookplates from the estate 
of C. W. Sherborn, the engraver, through his brother, Mr. Charles 
Davies Sherborn, of London, England. 
In view of the extensive changes in progress in the halls of the 
Smithsonian building assigned to this division, not only was the 
work of installation brought to a standstill, but it also became neces- 
sary to place the greater part of the exhibition collection tempo- 
rarily in storage. With the completion of the renovations and im- 
provements, however, the conditions surrounding the exhibits should 
be much improved. Notwithstanding the inconveniences thus oc- 
casioned, much work was done upon the collections, including the 
preparation, remounting, and labeling of display material. 
The section of photography also came into possession of valuable 
exhibition material. A collection of talbotypes, also called calotypes, 
made by the inventor, Henry Fox Talbot, was presented by Mr. 
C. H. Talbot, of Chippenham, England. A series of photographs of 
stellar spectra, apparatus, etc., was contributed by the Harvard 
College Observatory, through Prof. E. C. Pickering, director; and a 
fine lot of photomicrographs of disease germs, illustrating the use 
of photography in laboratory investigations at the Rockefeller In- 
stitute for Medical Research, was received as a gift from that insti- 
tute. The Alfred Stieglitz collection of pictorial photography was 
purchased at a nominal price from Mr. Stieglitz, of New York, to 
whom the Museum is greatly indebted. Mrs. Julian James, of Wash- 
ington, presented a large series of graphoscopic and stereoscopic 
views, and the Eastman Kodak Co., of Rochester, N. Y., con- 
tributed an excellent representation of the history of the hand 
camera. Through the kind offices of Mr. George W. Harris, of 
Washington, a portrait from each of nine of the leading portrait 
photographers of the country was secured to form a group illustra- 
tive of professional portraiture.
