A chronological outline of the history of meteorology in the United States 

 of North America [Mo. WcathcrRcv., 37 {]!)0!)), Xos. 3, pp. 87-80; J,, pp. J',6- 

 lJi9; J. pp. 17 8-1 HO). — This is a chronology of what are regarded as the most 

 important events in the history of the science of meteorology, which has been 

 prepared " to meet a somewhat general demand for the information it contains." 



Beport of the Iowa Weather and Crop Service for 1908, G. M. Chappel 

 {loicu Yearbook Ayr.. '.) [I'.IOS), pp. 3-'j7, df/iiis. 10, cltart /). — "This report i.-s 

 a condensation of the monthly and weekly bulh^tins and reports of the Iowa 

 Weather and Crop Service. It contains, in a condensed form, all of the" salient 

 climatic features of the year, together with tabulated statistics of the staple 

 soil products of the State." 



Fourth annual report of the meteorological committee (Ann. Rpt. Met. 

 Com. [Gt. Brit.], Jf {190'.)). pp. l-'/O, pis. .'/, fig. 1). — This consists as usual of 

 administrative reports regai-ding organization and operations (during the year 

 ended March 31, 190S) in marine meteorology, forecasts and storm warnings, 

 climatology, publications, investigation of the upper air, and miscellaneous sub- 

 jects, with appendixes as follows: Financial statement, supply of information 

 to the public, lists of observers who sent in " excellent " meteorological logs 

 during the year and of logs and documents received from ships, distribution 

 of instruments, report on inspection of meteorological stations, and lists of per- 

 sons and institutions from whom publications and meteorological data have 

 been received and to whom i)ublications are sent.. 



In 1908 the percentage of complete success in forecasts for the British Isles 

 was 58, of the sum of complete and partial successes 92. This is above the 

 average for 10 years. 



The mean temperature of the air at sea level, calculated as a function of 

 geographical longitude, latitude, and season of the year, H. Fritsche {Die 

 mittlere Tempcratur der Luft im Meeresniveau, dargesteUt als Funktion der 

 geogruphisehen Ldnge, Breite uiid Juhre.'izeit. Riga, 1909. pp. I'lJ,, 2)ls. 7). — The 

 calculations are given in detail in tabular form. 



On the probable influence of the movement of the moon on atmospheric 

 radioactivity, P. Besson {Compt. Rend. Anid. Sei. [Paris], 1 ',9 {1909), So. 

 15, pp. 595-597). — The meteorological relations of this influence were studied. 

 It was found that with the passage of the moon to meridian the radioactivity 

 increases while the atmospheric pressure decreases, and that with a constant
