Meteorology, P. Bqname {Rap. An. fita. Ayron. Mauritius, 190.'), pp. 1-10). — 

 Obscrv.itions on atmospheric pressure, temperature, precipitation, humidity, 

 and evaporation in Mauritius during 190.5 are summarized. 



A marked fall of barometer preceding tornadoes which passed over or near 

 the island is recorded. The year w-as unusually wet, the mean annual humidity 

 being 88.4, the rainfall 2.410.2 mm., 50 per cent higher than for the previous 

 year. The number of rainy days was 326 and the annual evaporation 

 .'^76.2 nnn. 



Meteorological observations for the year 1905 at the Ploti Agricultural 

 Experiment Station, M. Svolinsky {Ghodichnuii Otchct Plot)/. ,Selsk. Khoz. 

 Opuitii. tStaiitzii, II {1905). pp. l-2Ji, 121-12ff). — As in previous years, observa- 

 tions are reported on atmospheric precipitation, snow cover, evaporation, humid- 

 ity of the air, temperature of the air and soil, sunshine, solar radiation, atmos- 

 pheric pressure, and winds, with some description of the self-registering 

 apparatus used. The characteristic features of the season 1905 were a marked 

 deficiency of rainfall, especially during the summer, high temperatures of the 

 Jiir and soil, and increased sunshine. 



Some facts about the weather, W. Marriott {London: Edicard Htunford. 

 1906, pp. 32; rev. in Nature [London], ?// {1906), No. 1917, p. 29.')). — A popular 

 discussion of the subject esjiecially adapted to the British Isles. 



Weather forecasting from synoptic charts, A. J. Henry {./our. Franklin 

 In.st.. 162 (1906), No. J. /*/). 291-.M6. fifis. 6). — This method, based upcm two 

 well established facts, namely. (1) the general eastward drift of the atmos- 

 phere in temperate latitudes of the Northern Hemisphere, and (2) the close 

 relation between the weather and the distribution of atmospheric pressure, 

 is described and the gain in accuracy, length, and usefulness of weather fore- 

 casts is discussed. 



The recently organized weather service for North Germany, R. Bornstein 

 (Mitt. Deut. Landir. GescU., 21 {1906). Xo. .il. pp. 313, 31.'i).— This service is 

 briefly described.
