General weather review, 1910-11, W. M. Esten and C. J. Mason (Connect- 

 icut Storrs 8ta. Rpt. 1910-11, pp. 579-597, figs. 2).— A record is given of ob- 

 servations on tem]ierature and precipitation during each month of 1910 and 

 1911 at Storrs, the rainfall for 1910 and 1911, the monthly mean temperature 

 and monthly precipitation for the 23 years, 1888 to 1910, and dates of the last 

 and first killing frosts for the 24 years, 1888 to 1911. The mean temperature at 

 Storrs during the 24 years has been 47.1° F., the highest 99°, and the lowest 

 —14°. The mean annual rainfall has been 45.35 in., the longest growing season 

 184 days, and the shortest 131, the average date of the last killing frost in the 

 spring. May 4, and of the first killing frost in the autumn October 8. 



Meteorological observations (Maine St a. Bui. 191, pp. 329-331). — Observa- 

 tions at Orono, Me., on temperature, precipitation, cloudiness, and wind during 

 1911 are compared with the means of similar observations for 43 years. The 

 mean temperature for 1911 was 43.62° F., the mean for 43 years 42.39° ; the 

 precipitation for 1911 was 36.06 in., for 43 years 43.30 in.; the snowfall for

 cloudy days 133; total movement of wind in miles, 54,526. A table is also 

 given which shows the monthly and annual precipitation during 1911 at 18 

 different places in Maine. 



Report of the meteorologist, F. Stockton (Neic Mexico Sta. Rpt. 1911, pp 

 50-55). — Summaries of observations at the station from 1905 to 1911 on tem- 

 perature, precipitation, and dates of first and last killing frosts, and from 1906 

 to 1911 on storms and wind movement are given.

 pts. 1, Cartes 16-19, pp. 62, figs. S; 3, Cartes 16-19).— The meteorological and 

 cliraatological conditions of Finland are shown in a series of charts which are 

 briefly discussed. A bibliography of the more important literature on the sub- 

 ject is given. 



"Red rain" dust, T. Steel (Chem. News, 105 (1912), No. 27Jf2, p. 282).— 

 An analysis of dust which fell in Sidney October 11, 1909, is reported, indicat- 

 ing the material to be mainly sand and clay with 0.22 per cent phosphoric acid
