The lowest line in each gives the mean montfily fall of rain. It will be 

 seen, from an inspection of the numbers, that there is no regular progression 

 in the amount of rain-flill throughout the year, such as is observed in the phe- 

 nomena of temperature or humidity. In Dublin the greatest rain-fall, in the 

 mean of the eleven years, occurs in October, and the least in February ; their 

 amounts are 3'34 and 1-74 inches respectively. At Armagh the maximum is 

 in January, and the minimum in May; and they amount to 3'7.5 and 215 

 inches. The mean yearly raiu-fall at Dublin is 29'14 inches; that at Armagh 

 is 34'68 inches. 



The following Table gives the monthly fall of rain in the year 1851, at 

 all the meteorological stations: —

Stations. 



It will be seen from the foregoing Table, that the greatest diversity exists 

 in the amount of rain-fall in different localities. To render this more apparent, 

 and to facilitate the examination of the causes which influence the distribution, 

 I have, in the following Table, given the yearly rain-fall at the several stations 

 arranged in the order of magnitude, beginning with the smallest : —
