710 EXPERIMENT STATION RECORD. 



Report of progress in agricultural chemistry in 1906, T. Dietrich 

 {Jalncsbrr. Ayr. Clicin., 3. .scr., <J (1906), pp. XXXVIII+625).— This volume 

 reviews as usual, by abstract of the more important articles and by title of 

 those of less importance, the published account of the work of 1906 in the 

 whole field of agricultural chemistry. 



Yearbook of chemistry, edited by K. Meyer (Jalirbiirh dcr Vhemie. Bruns- 

 wick, 1901, pp. XII-\-631). — The more important contributions to plire and 

 applied chemistry during the year liiOtJ are reviewed. 



The chemistry of commerce, It. K. Duncan {^Xcw York and London, 1907, 

 pp. Xlll-\-263, pis. 32). — This is an "attempt to interpret into simple terms 

 and for educated lay-folk some new science in its relation to modern industry," 

 the object being to impress upon practical men the applicability of science to 

 industry. The portions of the book dealing with subjects of special- agricultural 

 interest are the chapters on nitrogen fixation and industrial alcohol. 



METEOROLOGY— WATER. 



The origin and the purpose of the Mount Weather Observatory, W. L. 

 Moore {U. *S'. Dept. A<jr., Bui. Mount Weather Observ., 1 {1908), pt. 1, pp. 

 7-11). — This is a brief general statement by the Chief of the Weather Bureau, 

 introducing the first number of a proposed series of quarterly bulletins report- 

 ing the results of the scientific work of the observatory. 



The methods and apparatus used in obtaining upper-air observations at 

 Mount Weather, Va., W. R. Blair (U. »S. Dept. Agr., Bui. Mount Weather 

 Ohserr., I {190S), pt. I. pp. 12-r>7. pis. 9. pus. 3. charts ,i).— The methods and 

 apparatus are described and illustrated, with tabulated records of a series of 

 kite flights during June to September, lt)07, and upper-air isotherms drawn 

 front the observations. 



The use of upper-air data in weather forecasting, A. J. Henry ( U. »S'. Dept. 

 Agr., Bui. Mount Weather Obscrr., I {I90S), pt. /. pp. 58-63, cliarts 3). — This 

 article discusses the bearing of observations at different elevations of pressure, 

 temperature, humidity, and wind movement on the development and movement 

 of weather changes, making si)ecial application of observations with kites at 

 Mount Weather Observatory during the sunmier of 1907.
