METEOROLOGY. 



By Cleveland Abbe. 



PREFATORY NOTE. 



The following images take up the subject of Meteorology and closely 

 allied matters where our last summary closed, and present a series of 

 short abstracts and notes relative to the princijjal meteorological items 

 that have been published up to the end of 1884 in the special meteor- 

 ological journals, namely, the Zcitachrift of the Austrian Meteorological 

 Association {Z. 0. G. 31.), Vols, xviii, xix; the Zeitschrift of the Ger- 

 man jMeteorological Association (J). M. Z.), Vol. I; the American Journal 

 of Meteorology {A. J. J/.); the English Journal Nature^ Vols, xxvii, 

 xxviii, XXIX, and xxx. 



The compiler has, even more frequently than in former years, taken 

 the liberty of adding to these abstracts occasional remarks of his own, 

 generally historical, which, to avoid confusion, are now inclosed in 

 brackets, f ], and he hopes that these will not be taken amiss by the 

 reader and those to whom they may refer. 



By numbering each of the items in a heavier type, and by an index re- 

 ferring directly to these articles, the reader will, it is hoped, utilize the 

 information here brought together more easily than by relying solely 

 upon the general arrangement of the twelve chapters. — C. A.
