Meteorological notes for the year ending- September 30, 1904, A. Lander 

 ( East Kent Sci. and Nat. Hist. Soc. Rpt. and Trans., .'. ser., ', I 1904), pp. 81 iO,pl. /, 

 fig. t). — The weather conditions at Canterbury during the year are brieflj summa- 

 rized and the telluradiometer, "a new instrument for accurately measuring ten 

 radiation and foretelling the weather by indicating the variations in the am. Him ol 

 aqueous vapor present in the atmosphere," is briefly described. 



Periodic variation of rainfall in the arid region, W. B. Stockman i U. S. Dept. 

 Agr., Weather Bur. Bui. .V, pp. 15, map 1). This is a paper which was read before 

 the Twelfth National Irrigation Congress at El Paso, Texas, November, 1904, and 

 summarizes information relating to the character, distribution, and amount of pre- 

 cipitation throughout the arid region of the United States. Data are compiled " for 



a few stations in each state, selected so as to best show the average c litions that 



have obtained generally over the State and region, due consideration also being 

 given to length and continuity of record and altitude of station." 



Climate of the Province of San Luis, Argentine Republic, A. L. Cravetti 

 (An. Min. Agr. Argentina, Secc. Agr. (Agron.), / (1904), No. 5, -pp. 67-88). — This is 

 one chapter of a detailed report on the agricultural conditions of this province, sum- 

 marizing the meteorological conditions (temperature, pressure, rainfall, wind I of the 

 region. 



Climate of the Province of Buenos Ayres, Argentine Republic, R. .1. Huergo 

 (An. Min. Agr. Argentina, Secc. Agr. (Agron.), 1 (1904), No. 2, pp. 72-88). — This 

 article forms part of a detailed report on the agricultural conditions of this province, 

 [t summarizes the available meteorological data with reference to diurnal variations 

 in temperature, average and extreme monthly temperatures, mean temperatures for 

 different stations, winds, atmospheric pressure and humidity, and rainfall. 



The action of cannon used for protection against hail, J. Violle < Compt. 

 Rend. Acad. Sci. [Paris'], 140 ( 1905), No. 6, pp. 842, 848).— The results of hail pro- 

 tection experiments made during 11*04 by the Syndicate of Beaujolais over an area of 

 about 12,000 hectares, and also tests made in Cote-d'Or are summarized. It is 

 claimed that the results are encouraging and indicate that the cannonading tends to 

 restore the electrical equilibrium and so mitigates storm conditions.

Influence of the temperature of the earth's surface, of thermal inertia, 

 and of radiation on errors in the determination of the temperature of the 

 air, P. Borisov (lzv. Moscov. Selsk. Khoz. Tnst. (Ami. Tnst. Agron. Moscou), 10(1904), 

 No. 8, />/'. 546-594). — This article reports data collected at the Moscow Agricultural 

 Institute, which show that the temperatures registered by thermometers in shelters 

 differ from those of the free air, being influenced by the temperature of the surface 

 of the soil or of the plant cover, the direction and movement of tire wind, radiation 

 from the shelter, etc.; and it was further noted that the temperature in an ordinary 

 wild shelter lags behind that of the air, sometimes to the extent of one hour.—

On the presence of formaldehyde in the atmosphere of towns, A. Trillat 

 (Bid. Soc. ('him. Paris, 8. ser., 88 (1905), No. 7, j>/>. 898-895). — Studies similar to 

 those reported by Gautier and Levy and Henriet (E. S. R., L5, p. 957; 16, p. 238) 

 are reported. A method of preparing a neutral chlorhydrate of rosaniline test paper
