In every month the S.W. wind is a multiple of every other 

 wind. In January, July, and August, this wind averages one- 

 third of each of these months, and nearly one-third in October. 

 In April its mean continuance is nearly a third of the month, 

 and in all the remaining months its duration is something more 

 or less than one-fourth. 



The mean yearly continuance 



Of the north wind is 40"70 days. 



Of the north-east wind , 47"60 days. 



Of the east wind 22 - 55 days. 



Of the south-east wind 19'90 days. 



Of the south wind 34*20 days. 



Of the south-west wind lOi'OO days. 



Of the west wind 38*30 days. 



Of the north-west wind 24 - 10 days. 



Of calm wind 33*70 days. 



RAIN GUAGES. 



Some persons having asked for information on the subject of 

 rain guages, they may be glad to know that Mr. Symons, who 

 is the great authority on all rainfall subjects, recommends a 

 guage five inches in diameter, made by Apps, No. 433, Strand, 

 London; Cassella, Hatton Garden, London; and Messrs. ISTeg- 

 retti and Zambra, Hatton Garden, London. It consists of an 

 external tin case with a funnel, and a holder inside the guage. 

 The measuring glass is also inside the case. All that is neces- 

 sary in order to record the rainfall is to measure the quantity 

 collected in the holder by pouring it into the measuring glass, 

 and then making a memorandum of the quantity so ascertained, 

 whenever the rainfall amounts to 0*01 of an inch. The mea- 

 surement should be made at nine a.m. A record should be kept 

 of the number of wet days in each month, i.e., days on which 

 0-01 of an inch of rain falls. These guages are supplied at 10/6 

 each; and if obtained through Mr. G. J. Symons, of !No. 136, 

 Camden Road, London, will be supplied accurately tested, with- 

 out additional charge.
