[Meteorological observations in Denmark] (S/o/is-. Aarhuf/ Damnarlc, l.'f 

 (J HO!)), ii/i. Is'i-JHG). — Tables are given which show the average temperature 

 for 40 years. 1S61 to 1900, and for each year from 1001 to 1908; the maximum 

 and minimum temperature for 19(K) to 1908; the pressure of the air. direction of 

 the wind, and storms for 187.3 to 1008; preci])itation, 1801 to T.MtS; and dates 

 of frost. 1874 to 1908. 



Meteorological and magnetic observations, M. Ruikatciiev et al. (Ann. 

 Ol/scrr. I'lii/s. Cent. Mcolus, IHOG \inih. ]<)0!)\, pt. J, pp. // 77). —Detailed data are 

 given for observations during 1900 at the Constantin Observatory at Pavlovsk, 

 the Nicolas Central Physical Observatory at St. Petersburg, and the observa- 

 tory of P^katerinburg. The observations include data for atmospheric pressure, 

 temperature of the air and soil, precipitation, snow and frosts, sunshine, and 

 magnetic and electric conditions. 



Report on the work of the station of agricultural climatology of Juvisy 

 during 1908, C. Flammarion {Bill. Mens. Off. Rrnscig. Agr. [/'rn/.s], ,s' ( IHO!)), 

 No. 8, pp. 1089-1123, figs. 10). — As usual, this report contains records of ob- 

 servations on atmospheric pressure, the temperature of the air, soil (see also 

 p. 521), and underground water, the I'elative humidity, rainfall, sunshine, 

 cloudiness, radiation, and wind, influence of different colored lights and of the 

 moon on growth of ])lants (p. r>29), and the falling and renewing of leaves. 

 The data are recorded in tahh'S and diagrams. 



Composition of Barbados rainfall {Rjit. Agr. Work Barbados, Imp. Dcpt. 

 Agr. West Indies, 1906-1908, p. 3). — The amount, distribution, and composition 

 of the rainfall at Dodds Botanic Garden during 1900 to 1908 are given in 

 tabular form. The total rainfall from December, 1900, to May, 1908, was 59.02 

 in., containing approximately 201.5 lbs. of chlorin and 9.64 lbs. of nitrogen per 

 acre. 



Fertilizing value of rain water, T. Weebon (Ann. Rpt. Dept. Agr. and Stock 

 [QuecnsJand], 1908-9. pp. 59, 60, 77, 7.S). — Observations extending over 18 

 months, 1907-8, at three places in Queensland, one having a tropical rainfall, 

 another a moderate rainfall, and a third a light rainfall, are reported. The an- 

 nual rainfall at these places varied from 26 to 75 in., but the amount of nitrogen 

 supplied to the soil by the rain water was practically the same (3 to 4 lbs. per 

 acre). In the tropical rainfall nitrate nitrogen exceeded ammoniacal nitrogen. 

 Data are reported showing that the rain at the beginning of showers contains 

 more combined nitrogen than toward the end and that during heavy showers 

 the amount of nitrogen is less than during light showers. 



Agricultural and industrial hydrology of Argentina, E. H. DtiCLOUX (In 

 Censo Agropecuario Nacional la Ganaderia y la Agricultiira en 1908. Buenos 

 Aires: Govt., 1909, vol. 3, pp. 103-1 'i9). — This report deals with the character of 

 the surface, subterranean, and mineral waters of Argentina, as well as with 

 their classification and use for potable and medicinal purposes and for irriga- 

 tion. Analyses of a large number of samples from different parts of the 

 country are reported. 



Waters, T. Weedon (Ann. Rpt. Dept. Agr. and Stock [QiieenshnuU, 1908-9, 

 pp. 60, 78). — Analyses of a large number of samples (including artesian waters) 

 examined not only for industrial purposes but also as to suitability for stock 

 and irrigation are reported. 



The farmer as an aquiculturist, J. Heyking (Dent. Landw. Presse, 37 (1910), 

 No. Jf, pp. 33-35). — This article discusses the ix)ssibilities of increasing the pro-
