METEOROLOGY. 



The most interesting feature in the progress of meteorology dur- 

 ing the year has been the increasing attention paid to the deductive 

 study of atmospheric movements, as evidenced by the works of Blan- 

 ford, Ley, Hann, Mohn, and Goldberg, all of whom have contributed 

 to a clearer knowledge of the rationale of the winds and currents of 

 the air. In climatology we have to record the publication by the 

 Smithsonian Institution of the temperature tables and the winds of 

 the globe. New data have also been published from regions hitherto 

 but little known such as the volume of meteorological observations 

 in the Amoor Valley, edited by Von Schrenck, for the St. Peters- 

 burg Academy of Sciences ; the monthly barometric and other means 

 for stations in the Argentine Confederacy, published by Dr. Gould ; 

 the two volumes of details of observations published by the Cana- 

 dian government. 



Of daily weather maps, those published by the Danish and the 

 United States Weather Bureaus have the widest circulation ; the for- 

 mer has been extended so as to form a continuation of the United 

 States maps. The daily bulletin of simultaneous observations, taken 

 throughout the world at 7.35 A.M., Washington time, has been main- 

 tained by the Army Signal Service ; and the specimen maps pub- 

 lished of a weather chart, embracing the entire northern hemisphere, 

 show that when published for every day, these will mark a new 

 epoch in meteorology. 



We have in the following summary briefly noticed some of the 

 meteorological events of the year and the publications that have 

 been received, arranging the notes, as far as possible, in the follow- 

 ing order, viz. : 



A. Meteorological Societies, Institutions, and Individuals. 



B. " Instruments and Methods, 



C. " Investigations and Results. 



A. Institutions and Persons. 



At the Geographical Congress at Paris a letter of merit, being the 

 highest award there recognized, was presented to the United States 

 Army Signal Service for the perfection of its organization and the 

 usefulness of its works.
