Again, I obfcrve that it generally rains lefs in March 

 than in November in the proportion at a medium of feven to 

 twelve. 



It generally rains lefs in ^pril than in OBobcr in the propor- 

 tion of one to two nearly at a medium ; I believe it to be other- 

 wife in Ireland. 



It generally rains lefs in May than in September ; the chances 

 that it does fo are at leaft as four to three ; but when it rains 

 plentifully in May (as 1.8 inches or more) it generally rains 

 but little in September ; and when it rains one inch or lefs in 

 May, it rains plentifully in September; this applies not only 

 to England and Ireland, but alfo I believe to all the weftern 

 parts of Europe. 



If we had tables of the quantities of rain that fall in each 

 month for eighty or one hundred years, we might calculate 

 the mean proportion of each, whether taken fingly or in groups, 

 and thence deduce the probable quantities of rain in the fuc- 

 ceeding months ; the table would every year grow more perfed, 

 and in time approach very near the truth. But I have met no 

 account of the quantities of rain that annually or monthly 

 fall in Ireland, nor any account of the weather except that 

 taken by the induftrious Dodlor Rutty with a view to medi- 

 cine ; his obfervations extend to forty- one years, but his 

 eftimations arc merely vague and popular. However, I fhall
