blications, investigation of the upper air, and miscellaneous subjects, 

 with appendixes as follows : Financial statement, supply of inform- 

 ation to the public, lists of observers who sent in " excellent " 

 meteorological logs during the year and logs and documents re- 

 ceived from ships, distribution of instruments, report on inspection 

 of meteorological stations, and lists of persons and institutions from 

 whom publications and meteorological data have been received 

 and to whom publications are sent. 



In 1908 the percentage of complete success in forecasts for the 

 British Isles was 58, of the sum of complete and partial successes 92. 

 This is above the average for 10 years. 



W. R. DUNLOP. Meteorology as a Branch of Agricultural 

 Science. [Rainfall Averages]. Agric. Gaz., LXX, London, 1909. 



Agriculture and climate are so intimately connected that the 

 study of meteorology seems to deserve a more prominent position 

 than is at present accorded to the subject. 



Rainfall averages are very instructive, and remain pretty cons- 

 tant. In England most rain falls in the autumn and least during 

 the spring. Going from the West of England to the East there 

 is a more or less steady gradient, starting with average 36 inches 

 in the West down to 26 inches in the Eastern Counties. Thus 

 the rainfall of different districts varies, and should where possible 

 be recorded from day to day. This would suggest how much more 

 rain could be expected. 



A proper understanding of the nature of dews and mists, eva- 

 poration and radiation, is of much use; the hygrometer and the 

 thermometer should be frequently referred to. The variation of 

 temperature from day to day should be noticed, and it should be 

 remembered, for example, that there is a greater daily range of 

 temperature in June than in January. 



The study of weather, like agriculture itself, is based on science, 

 but in practice it is an art; the study of it demands but a very 

 short time each day, but the work must be rigidly systematic, 

 otherwise it is absolutely valueless.
