812 ABBOTT LAWRENCE EOTCH. 



October 16, 1891, the Blue Hill forecasts were given to the Associated 

 Press and published in the papers of Boston and neighboring cities. 

 Since October 16, 1891, forecasts have been signaled by flags from Blue 

 Hill, and since July 9, 1911, local forecasts have been displayed at 

 the Observatory gate daily. 



Professor Rotch's list of published papers and books comprises 183 

 titles. These cover a wide range of subjects, by no means strictly 

 confined to meteorology, and show most emphatically how varied were 

 their author's interests; how extended was his reading; how alert 

 and progressive he was in all he undertook. These 183 titles in them- 

 selves furnish a satisfactory outline of the development of meteoro- 

 logical science during the past 25 years. In addition to the " Charts 

 of the Atmosphere" just referred to, he published two other books, 

 "Sounding the Ocean of Air," (1900) and "The Conquest of the 

 Air" (1909). 



Professor Rotch gave his support freely to a large number of scien- 

 tific societies and undertakings. He was one of the pioneer and most 

 enthusiastic members of the New England Meteorological Society. 

 He was, for more than ten years (1886-96), one of the associate editors 

 and one of the mainstays of the American Meteorological Journal, 

 which did a unique work for American meteorology. 



He was elected a Fellow of the American Academy of Arts and 

 Sciences March 14, 1888, and served as Librarian from May 10, 1899, 

 until his death. He was a member of the Astronomical and Astro- 

 physical Society of America; a member and trustee of the Boston 

 Society of Natural History ; a member of the American Philosophical 

 Society, of the Physical Society of London, of the International Solar 

 Commission, of the International Commission for Scientific Aero- 

 nautics, of the International Meteorological Committee; fellow and 

 later Honorary Member of the Royal Meteorological Society (London) ; 

 member of the Societe Meteorologique de France, of the Deutsche 

 Meteorologische Gesellschaft, of the Oesterreichische Gesellschaft 

 fur Meteorologie, corresponding member of the Deutscher Verein 

 fiir Forderung der Luftschift'ahrt, and member of many other societies. 



He was lecturer at the Lowell Institute, in Boston, in 1891, and again 

 in 1898. He was a member of the International Jury of Awards at 

 the Paris Exposition (1889), and was then made a Chevalier of the 

 Legion of Honor. He received the Prussian Orders of the Crown 

 (1902) and Red Eagle (1905) of the Third Class in recognition of his 

 services in advancing the knowledge of the atmosphere. Further
