Rain. — The quantity of rain is within the 7- 100th of an inch of the 

 fall in 1845. The total quantity in 1846, is 49*134 inches, of which 

 17 inches fell in July and October. The quantity measured from the 

 steeple of St James* Church, 78 feet above the street, is 35*422 inches, 

 or 2 inches more than in the previous year. The fall at Cleator, near 

 Whitehaven, is 55-16, or 2*16 inches more than in 1845, and 6 inches 

 more than at this place. The fall of rain in the first six months of the 

 year was greatly below the average ; on no one day did the quantity 

 amount to an inch in depth. In the last six months there have been 

 three days in which the fall was between 1 and 2 inches ; and two days 

 (both in July) between 2 and 3 inches. The wet days exceed those of
