14 EXPERIMENT STATION RECORD. 



A cold-storag'e evaporimeter, M. M. Hastings ( U. /S'. Dept. Agr., Bur. Anim. 

 Indus. Circ. l.'i'.), pp. 8, ]i(j. 1). — A practical apparatus for determining tlie hu- 

 midity in cold-storage houses which store cheese, eggs, etc., is described. The 

 principle of the apparatus is the same as that recommended by Livingston of 

 the Carnegie Desert Laboratory (E. S. R., IS, p. 328). The substance employed 

 therein, however, is a dilute sulphuric-acid solution which, like other substances 

 of the same nature, has a certain more or less definite equilibrium vapor pres- 

 sure at which absorption and evaporation e(pialize each other. 



Refrigeration and the cold-storage industry, U. Ferretti (L'Industria del 

 Freddo. Rocca San Casciano, Italy, 1909, pp. XI-\-li>i5, figs. 251). — This volume 

 is an extended treatise on the cold-storage industry from the standpoint of 

 agriculture, commerce, hygiene, horticulture, etc. Refrigerating machines, the 

 production of artificial ice, food preservation, and other topics are considered. 



A bibliography is appended to the volume.

study of meteorology as a branch of agricultural science, W. R. Dunlop 

 {Agr. Gaz. [London^, 70 (1909), No. 1855, p. 57).— This is a brief article ex- 

 plaining the relation of the more common weather observations to weather pre- 

 diction, and intended to encourage the giving of more attention to this subject 

 by farmers. 



Treatise on physical geography, E. de Martonne (Traits de O^ographie 

 Physique: Climat, Hydrographie, Relief du Sol, B log eo graphic. Paris, 1909, 

 Nos. 1, pp. 20.'t; 2, pp. 202, illus.; rev. in Rev. Gen. Chim., 12 {1909), No. llf, pp.

 {1909), pp. 168-113, figs. 2). — The climatic conditions in Wyoming are briefly 

 summarized with reference especially to so-called dry farming. 



Meteorological, magnetic, and seismic observations of the College of 

 Belen of the Society of Jesus, Havana, 1907 and 1908, L. Gangoiti {Oh- 

 servatorio Meteorologico, Magnetico y Seismico del Colegio de Belen de la Cam- 

 pania de Jesus en la Hahana, afio de 1907, 1908. Uavana, 1908, pp. 90, dgms. 3;

 the usual observations. 



The climate of Buenos Aires in 1908 {Yearbook City Buenos Aires, 18 

 {1908), pp. 3-9). — Observations on pressure, temperature, rainfall, humidity, 

 sunshine, vapor pressure, and wind are summarized for each month of the year 

 and for each 10-day period. Determinations of the amount of ozone, carbon 

 dioxid, free and organic ammonia, and bacterial content of the air, and of 

 organic and free ammonia and nitrous and nitric acid in rain water are also 

 reported. 



The weather during the agricultural year 1907-8, F. J. Brodie {Jour. Roy. 

 Agr. Soc. England, 69 (1908), pp. 384-393) .—The general character of the dif- 

 ferent seasons in the United Kingdom is described and summary tables of ob- 

 servations on temperature, sunshine, and rainfall are given. 



Meteorological observations (Stnfis. Ycariook [Natal], 1908, pp. 26-30). — 

 Tables give observations on pressure, temperature, rainfall, cloudiness, and 

 wind during the period from 1885 to 1908 at Durban, and on temperature and 

 rainfall during the period from 1894 to 1908 at a number of other places in 

 Natal.
