April with the temperature of an Itahan June." A controlHng c-Hmatic factor is tl e 

 winds. "The prevailing winds are the northeast trades, at a teniperature of about 

 70° F. and a saturation of about 65 per cent, but these are greatly modified by tlie 

 mountain masses." These modifications are explained. 



Studies on the statics and kinematics of the atmosphere in the United 

 States, F. H. Bigelow {U. S. Dept. Agr., Weather Bureau Doc. 273, pp. 62, jiga.

 80, 117, 163, 250, 304, 347, and deal with a new barometric system for the United 

 States, Canada, and the West Indies; methods of observing and discussing the 

 motions of the atmosphere; the observed circulation of the atmosphere in the high 

 and low areas; review of Ferrel's and Oberbeck's theories of the local and general 

 circulations; relations between the general circulation and the cyclones and anti- 

 cyclones; certain methematical formulae useful in meteorological discussions; and a 

 contril)ution to cosmical meteorology. 



Report on the work of the Station of Agricultural Climatology of Juvisy 

 during the year 1901, V. Flammarion {Aim. Min. Agr. [F/vf/)rr], 21 {1902), Av. 

 2, pp. 395-421, figs. 14). — As in previous years (E. S. R., 13, p. 627), observations 

 were made on temperature of the air and of the soil at different depths, atmospheric 

 jiressure, humidity, rainfall, cloudiness, duration of sunshine and solar radiation, 

 and underground waters, and also on the shedding and renewal of leaves, the action 

 of solar rays of different colors on plants and animals (silkworms), and the influence 

 of electricity on plants (see p. 54S).

Rainfall in the agricultural districts of Queensland, C. L. Wragge ( Queens- 

 laml Agr. .Tour., 11 {1902), No. 3, p. 208). — This is a summary of observations at 41 

 different places in Queensland during the year ended July 31, 1902. 



Meteorology {Trans, and Proc. Nor Zealand Inst., 34 {1901), pp. 595, 596). — A
