260 SCIENTIFIC RECORD FOR 1884. 



present undertaking seems to have been given by letters from various 

 meteorologists suggesting to Professor Harrington the hope that ho 

 might undertake it. So far as the financial success of this journal Is 

 concerned there can evidently be no doubt, provided its columns suc- 

 cessfully combine the scientific and the popular features that in Ger- 

 many have been divided between the two journals published at Ham- 

 burg and Magdeburg, respectively. 



Among the principal articles that have appeared in the journal during 

 1884 are the following: 



Prof. T. C. Mendenhall, History of the Ohio State Meteorological 

 Bureau, established April 17, 1882. 



Prof. H. M. Paul, Barometric Waves of Very Short Period. 



Prof. William M. Davis, Wii:ds and Currents of the Equatorial 

 Atlantic. 



A. J. Phinney, The Oakville Tornadoes. 



Prof. H. A. Hazen, Exposure of Thermometers. The Sling Psy- 

 chrometer. 



Lieut. J. P. Finley, Tornado Predictions. 



Prof. William M. Davis, The Relation of Tornadoes to Cyclones. 



H. H. CUiyton, Meteorologic Cycle. (Showing a barometric and 

 rainfall oscillation every twenty-five months.) 



Ct. K. Gilbert, Tornado Predictions. 



Prof. H. A. Hazen, Toruado Generation. 



L. A. Sherman, Movements of Weather- Areas. 



H. H. Clayton, The Thunder Squalls of July 5, 1884. 



H. M. Paul, Thermometer-Exposure. 



Prof. F. H. Loud, Diurnal Wind Variation at Colorado Springs.

 and the meteorological instruction in colleges, another powerful help in 

 scientific progress is the organization of meteorological societies in the 

 United States. An occasional paper on some meteorological subject is 

 read before some geographical or scientific society, the most active in 

 this respect being the Philosophical Society of Washington, in which 

 there is material sufiicieut to form a special meteorological section. An 

 efibrt was made at the Philadelphia meeting of the American Associa- 

 tion for the Advancement of Science to secure the recognition of meteor- 

 ology by organizing a sectii^n of terrestrial physics as distinguished 

 from molecular physics, and this may possibly be accomplished on some 

 future occasion. The honor of establishing the first special society for 

 the study of our science belongs to Prof. W. Upton and Mr.E.B. Weston, 

 both of Providence; Mr. W. M. Davis and Prof. W. H. Niles, of Cam- 

 bridge; Mr. D. Fitzgerald, of Boston, and a few others (including the 

 present writer), who held the first preliminary meeting of organization 

 in June and the first annual regular meeting on the 21st of October, in 

 Boston. This society will for the present make a special effort to secure 

 move numerous i-aiufall, thunder-stormj and possibly other siiecial ob-
