West Indian hurricanes, E. B. Garriott ( V. S. Dept. Agr., Weatlier Bureau Bui. 

 H, pp. 69, chart.^ 7). — "This paper reviews the writings of the more prominent 

 meteorologists of the nineteenth century, so far as they refer to the tropical storms 

 of the North Atlantic, and presents a chronological list of West Indian storms for 

 400 years. It grajihically illustrates and describes the more important hurricanes 

 that have occurred during the last 25 years, and contains accounts, based upon local 

 records and ol)sorvations, of liistorical storms of the West Indies." 



Prevention of hail storms by cannon, J. C. Covert (K 8. Consular Bpts., 65 

 {1901), No. 245, pp. 231-235, figs. 2). —This is an account of observations made during 

 a visit to the towns of Bois d'Oinget and D6nice, in the south of France, where the 

 method of cannonading to prevent hailstorms, described by Vermorel (E. S. R., 12, 

 p. 316), is practiced. The 1)eUef of the wine growers in the efficacy of this method, 

 as demonstrated by experience during 1900, is stated to be emphatic.
