Smithsonian Miscellaneous Collections. — Thirty papers were added 

 to the Miscellaneous Collections, including a number of biological 

 and anthropological articles, and four volumes of considerable size 

 on The Mechanics of the Earth's Atmosphere, Landmarks of Botan- 

 ical History, Bibliography of Aeronautics, and Recalculation of 

 Atomic AVeights, all of which are enumerated in detail in the appen- 

 dix to this report. 



Among the papers published just at the close of the year was one 

 by Dr. F. W. Clarke on " Chemical denudation " and one by Dr. 

 George F. Becker on the " Age of the earth." 



The Smithsonian Physical Tables have been revised and extended 

 to bring the work within the range of recent advances in the science 

 of physics, and the new edition has been put to press. The several 

 series of Smithsonian meteorological, geographical, physical, and 

 mathematical tables continue to be in demand by students, and new 

 editions are required at comparatively frequent intervals. 



As mentioned on another page, three papers have been added to the 

 series descriptive of my researches in Cambrian Geology and Pa- 

 leontology, 



Harriman Alaska Expedition. — Arrangements are being made by 

 which the publication of the series of volumes on the results of the 

 Harriman scientific expedition to Alaska in 1899 will be transferred 

 to the Smithsonian Institution and the work will hereafter be known 

 as the Harriman Alaska series of the Smithsonian Institution. The 

 remainder of the edition of the 11 volumes privately printed, as 

 well as volumes in preparation, will bear special Smithsonian title 

 pages, and all will be distributed under the auspices of the Institution.

 tions during the year included the annual report on its operations, 

 about 50 papers, chiefly biological, in the proceedings, 8 bulletins, and 

 7 botanical papers in the series of Contributions from the National 

 Herbarium. The most elaborate of these works is Bulletin No. 70, 

 devoted to the National Gallery of Art, by Assistant Secretary 

 Richard Rathbun. This book reviews the history of the Art Gallery 

 and gives a catalogue of the collections with illustrations of some of 

 the most important paintings.

 torical Association and of the National Society of the Daughters of
