oils employed in Germany, and the four charts of Prussia : 

 pressure, wind, and cloudiness on the 1st; temperature and 

 precipitation on the 2d; 24-hour changes in pressure on the 

 3d; and 24-hour changes in temperature on the 4th. Nu- 

 merous details are given with reference to the methods of 

 doing work in Germany, England, Denmark, France, Austria, 

 and Belgium. 



Under the misleading title of Physical Astronomy, the ed- 

 itor of Les Mondes republishes one of the last contributions 

 of Seech i to meteorology, in the shape of a short article writ- 

 ten in March, 1878, on the Prediction of the Weather. Sec- 

 chi's idea appears to be that, at least in Italy, the probability 

 of coming clear, cloudy, or rainy weather depends on the di- 

 rection of the wind and changes in the pressure ; and that the 

 prediction of future weather may be founded upon the con- 

 ditions of the atmosphere in the regions all around Italy, be- 

 cause the weather in that country will be the result of the 

 conditions existing in the surrounding countries. 



The Climate of Rome, by R. P. Ferrari, who succeeds Sec- 

 chi as Director of the Observatory of the Roman College, is 

 a valuable monograph compiled by Ferrari as a part of an 

 archa3ological and statistical monograph on Rome and the 

 Roman Campagna. It reviews the history of meteorology 

 since the year 1780, and the meteorological work of Phi- 

 lippe Gili (1797 to 1821), Calandrelli (1782 to 1801),Conti, 

 Du Monchel, and De Vico (1822 to 1854), and of Secchi 

 (1854 to 1878). He has drawn freely from the memoirs of 

 Respighi, Mancini, and Secchi. The last chapter of his work 

 is devoted to the hygienic conditions of the climate of 

 Rome. 



The meteorological journal kept by Tycho Brahe from 

 1582 to 1597 has been published by the Swedish Academy 

 of Sciences, under the editorship of Paul de La Cour, who 

 subjects the observations to analysis and. criticism. 



The climate of Eastern Switzerland is elucidated in a mem- 

 oir by Wanner in the annual report of the Association of St. 

 Galle. The suddenness of the changes in temperature at- 

 tending the occurrence of a Fohn wind is shown by a rise of 

 14.8 C.,or 32 Fahr.,in half an hour. 



Interesting notes on the climate of Greece are contributed 

 to the British Meteorological Society by Boys, of Patras. The,
