02 ANNUAL RECORD OF SCIENCE AND INDUSTRY. 



The Royal Academy of Copenhagen has published the 

 valuable meteorological observations of the famous astrono- 

 mer Tycho Brahe. The record extends over sixteen years 

 (1582 to 1597), and enumerates seventy-eight auroras; it 

 has been carefully analyzed by De la Cour. 



The Paris Observatory has published, the Atlas 3feteorolo- 

 gique ties Orages for 1875. This series of annual volumes 

 now embraces some of the most admirable memoirs that we 

 possess on subjects relating to thunder-storms. 



The Observatory at Sydney, Australia, has during the 

 year published a daily weather map, based, of course, on 

 telegraphic reports, and which may be expected to be the 

 precursor of a general map for Australia. 



The director of the Paris Observatory seems to have 

 taken the right course in encouraging the enterprise of the 

 New York Herald, which paper has endeavored to lay all 

 Europe under still further obligations to it by showing that 

 storm predictions are possible for Europe a week in advance. 

 This bold undertaking has been welcomed with considerable 

 popular applause in Great Britain and France ; but the more 

 conservative and rational students still continue to doubt 

 the possibility of real success in the undertaking twenty- 

 five per cent, of successful predictions will hardly overbal- 

 ance the seventy-five per cent, of failures that a careful ex- 

 amination of the weather maps has revealed. 



When in 18G8 the writer started the Daily Weather Bul- 

 letin of the Cincinnati Observatory, with its local predic- 

 tions, the proposition to furnish daily synopses to Leverrier 

 was gladly accepted by him, and a greater familiarity with 

 the subject, while serving to show the difficulties, has also 

 impressed him with the possibilities. A simple synopsis 

 of existing conditions on our side of the Atlantic would be 

 a decided help to the European students in their daily pre- 

 dictions. 



Since the death of Leverrier the advocates of a complete 

 separation of meteorology from the Paris Observatory have 

 made strong efforts to accomplish their aims. Probably 

 nothing will be done that is inconsistent with existing de- 

 crees. It seems to be felt in France that meteorology has 

 not made the advance that it should have done.
