Co., Harvey, 111., and a full size hand operated planetary trans- 

 mission presented by Henry Ford, Dearborn, Mich. An original 

 Knox automobile, made in 1900, was donated by Mrs. Lansing Van 

 Auken, Watervliet, N. Y. Important additions were made to the 

 series of calculating and writing machines by the Burroughs Add- 

 ing Machine Co. and the Corona Typewriter Co., and interesting 

 specimens were contributed by the signal section of the American 

 Railway Association through H, S. Balliet, secretary of the section. 

 The original K-III airplane was presented by James V. Martin, 

 who designed it in 1917 for combat service. Important additions to 

 the series illustrating the development of the incandescent lamp were 

 made by the Edison Lamp Works of the General Electric Co. 



American manufacturers who had been instrumental in building 

 up our textile exhibits, continued their interest both in providing 

 new materials and in renewing specimens in the older exhibits. The 

 exhibits illustrating various branches of the rubber industry received 

 important additions including the greater part of the American 

 exhibit at the Sixth International Rubber Exposition held in Brus- 

 sels in 1924, which was contributed by the Rubber Association of 

 America (Inc.), New York City. An important collection of bird 

 plumage and feather articles representing many thousands of dollars, 

 secured by confiscation from plume hunters, importers, and manu- 

 facturers for violations of the Federal laws for the protection of 

 birds, was acquired by transfer from the Biological Survey. 



The section of medicine received a number of interesting additions 

 to its public health exhibits, as well as a number of specimens of 

 individual interest, including the medals and decorations conferred 

 on the late Maj. Gen. William C. Gorgas, which were loaned by his 

 widow. 



Interesting additions to the graphic arts collections comprised sub- 

 stitutes for boxwood for wood engraving, examples of micro-engrav- 

 ing, bookbinding, prints, examples of fine papers, mezzotints, print- 

 ing for the blind, and other material. Important contributions were 

 received from various sources for incorporation in the traveling 

 exhibits of this division which have proved extremely popular. 

 The section of photography was enriched by three early forms of 

 Prosch shutters evolved in the course of experiments to automati- 

 cally control exposures and obviate the use of a lens cap; a view 

 camera of 1890; a reel of historical motion pictures; some remark- 

 able examples of telephoto photographs showing the Sierra Nevada 

 Mountains at a distance of 135 miles, and a number of beautiful 

 examples of pictorial photographs presented by well known experts 

 and experimenters in this line.
