and middle Plate?u and southwestern portions of the northern Plateau regions, and 

 the south and middle Pacific and southern portion of the north Pacific districts; 

 elsewhere it was above the normal. . . . The mean temperature was above the 

 normal in the Florida Peninsula, upper Lake region, North Dakota, Missouri Valley, 

 and the northern slope, northern Plateau, and Pacific regions; elsewhere it was 

 below the normal." The departures in temperature were as a rule small and "in 

 but few instances exceeded 1°, the greatest, +2.5°, occurred over the Red River of 

 the North Valley. . . . Over the country east of the Mississippi River the distri- 

 bution of precipitation was not well marked as to geographic districts, as excesses 

 and deficiencies of considerable amount occurred in the same district. To the west- 

 ward of the Mississippi River the lines of demarcation between the excesses and 

 deficiencies were much better defined as to geographical districts. Considering the 

 geographic districts as a whole the precipitation for the year was above the normal 

 in the Florida Peninsula, Gulf States, Missouri Valley, slope and southern and middle 

 Plateau and south Pacific regions; elsewhere it was below the normal."

Determination of number of hours of possible sunshine at Colorado 

 Springs, F. H. Loud {Colo. Col. Studies, 11 {1904), Sci. Ser. Nos. 33-35, pp. 7 7-82).—

Meteorology for the year 1905, J. Derome {Rev. Sci. [Paris'], 5. ser., 5 {1906), 

 No. 2, p. 53). — This a brief summary of observations at Paris on atmospheric pres- 

 sure, temperature, and rainfall compared with similar observations for 1903 and 1904. 

 The characteristic feature of the weather in the region of Paris during the year was 

 excessive rainfall. The rainfall at Park St. Maur was 641.1 mm. in 1905 as against 

 541 mm. in 1903 and 527 in 1904, the mean for 1841-1890 being 594 mm. There 

 were 169 rainy days in 1905, as against 159 in 1903 and 141 in 1904. The wettest 

 month was June, 108 mm. The heaviest daily rainfall, 27.2 mm., occurred August 28. 



The mean temperature of the year was 9.87° C, being lower than that of 1903 

 (10.38°) and 1904 (10.4°). The mean temperature for the period 1841-1890 was 

 9.93°. The highest temperature observed in 1905 was 32° C, the lowest -10.9°. 



The mean annual pressure was 758.97 mm. The normal for the period 1841-1890 

 was 757.6. The lowest barometer observed in 1905 was 730.3 mm., the highest 782.1. 



Meteorological summary for 1905, H. Dufour and D. Valet {Chron. Agr. 

 Vaud, 19 {1906), No. 3, pp. 49-54). — Observations at Lausanne on temperature, pre- 

 cipitation, sunshine, temperature of the soil, and general weather conditions are 

 briefly summarized for the year and compared with averages for previous years and 

 neighboring places.

Meteorological observations, G. Ginestous {Bui. Par. Agr. et Com. [Tunis'], 

 9 {1905), No. 37, pp. 590-614). — Tabular summaries are given of observations, 

 June to November, 1905, at a number of places in different parts of Tunis on pre- 

 cipitation, temperature, atmospheric pressure, humidity, evaporation, cloudiness, 

 direction of the wind, and casual phenomena. A brief account is also given of meteor
