BEPORT OF NATIONAL MUSEUM, 1924 105 



States patent rights on pill, tablet, and capsule machines. These 

 machines are used in the manufacture of medicines of various 

 forms, and these papers show the development of machinery of this 

 kind in the United States. Doctor Kebler also presented 16 port- 

 folios containing committee reports, circulars, and correspondence 

 relating to the ninth revision of the United States Pharmacopoeia. 



Ten illustrations and one pamphlet concerning the history and 

 development of the housing movement in Washington, also five 

 pamphlets relating to hygiene and sanitation were donated by Dr. 

 George M. Kober, Georgetown University Medical School, Wash- 

 ington, D. C. 



The American Red Cross Museum, Washington, D. C, through 

 Miss Irene M. Given wilson, curator, presented eight Upjohn child- 

 welfare posters. 



Thirty-eight pamphlets and one set of reports of investigations 

 of the Bureau of Mines, dealing with sanitation and safety in the 

 mineral industries, were obtained by transfer from the United 

 States Department of the Interior. 



A number of important and valuable additions to the collections 

 illustrating wood technology were received the past year. Probably 

 the most interesting were a cypress " knee " and cross section of one 

 of the logs removed from the excavation for the foundation and 

 basement of the new Hotel Walker at Connecticut Avenue and De 

 Sales Street, Washington, D. C, which were given by Dr. L. W. 

 Stephenson, of the Geological Survey. The survey has declared 

 that this cypress deposit can not well be less than 100,000 years old, 

 and that it may be much older. 



From the exhibition standpoint, the most important accession was 

 that of 56 products of the hardwood distillation industry received 

 as a gift from Penn Formaldehyde Manufacturing Co., East Smeth- 

 port, Pa., through the National Wood Chemical Association, Brad- 

 ford, Pa. This series includes specimens of maple, beech, and birch, 

 the three most used woods in the industry, and the products derived 

 from them by distillation, as well as a few of their compounds. In 

 connection with this, 43 photographs and 9 blue prints presented 

 by the National Wood Chemical Association form a valuable supple- 

 ment for anyone wishing to study the industry pictorially. 



The Grass Fibre Pulp & Paper Co., of Leesburg, Fla., contributed 

 32 specimens and four photographs showing the manufacture of 

 paper from Florida saw grass, a recent industry which promises to 

 add wealth to the State from the development of a hitherto useless 

 natural product. Kraft wrapping paper is to be the chief product, 

 and since true Kraft paper is made from soda wood pulp, the im-
