Smithsonian tahles.—lt has long been the practice of the Institution 

 to assist students and research workers by publishing compilations of 

 tables useful in all kinds of technical, industrial, and scientific work. 

 Since 1852, when the first edition of Prof. Arnold Guyot's "Meteoro- 

 logical and Physical Tables" was published by the Institution, thou- 

 sands of copies of the Smithsonian tables have been distributed 

 throughout the world. These volumes, which have fallen in four 

 categories (meteorological, physical, mathematical, and geographi- 

 cal), have been kept revised and reprinted as new data in these fields 

 became available. During the present year, three volumes of these 

 tables were in process: 



The sixth revised edition of the Smithsonian Meteorological Tables, 

 prepared by Kobert J. List, of the U. S. Weather Bureau, was ex- 

 pected to be off the press before the end of the calendar year 1951. 



The manuscript for the ninth revised edition of the Smithsonian 

 Physical Tables, compiled under the direction of Dr. W. E. Forsythe, 

 of Cleveland, was completed during the year and submitted for print- 

 ing estimates. 



The Institution accepted the manuscript for a new volume in the 

 mathematical series: Smithsonian Logarithmic Tables, prepared by 

 G. W. Spenceley, Rheba M. Spenceley, and E. R. Epperson, of Miami 

 (Ohio) University. These tables present 23-decimal-place values of 

 natural and common logarithms and will be published by the Institu- 

 tion under a grant from the Research Corporation of New York.
