Distribution of the Rainfall in each Month. — The nomenclature 

 used in the following account of the chief falls of rain is the same 

 as in my previous reports, falls of at least ^ inch being styled 

 considerable, | inch very considerable, 1 inch great, \\ inch very 

 great, \\ inch heanj. If inch very heavy, and 2 inches excessive. 

 This analysis only applies to the thirty-five stations for which 

 I have returns of the daily rainfall. The wettest days which are 

 given in each month are those at forty-two stations. 



jAJfUAKT. — Rather dry on the whole, but with much snow in the 

 second half of the month, and with more than the usual number of 

 wet days. On the 8tli the fall was considerable at twenty-four 

 stations and very considerable at two, and on the 22nd it was 

 considerable at one (Cowroast). The 7th was the wettest day at 

 one station, the 8th at forty stations, and the 6th and 22nd were 

 the wettest at one station. Mr. Bonner Hopkins reports that on 

 the 22nd snow fell at Fairhill, Berkhamsted Common, to the depth 

 of 3 inches, which should have shown about 0'25 in. of water in 

 the gauge, but that there was only 0-15 in. in it. 



rEBEXTAET. — A wct month, with snow during the first week, and 

 about the usual number of wet days. On the 1st the fall was 

 considerable at six stations and great at Northchurch (1*13 in.), 

 on the 4th it was considerable at thirteen stations, and on the 

 5th considerable at eight. The 1st was the wettest day at twelve 

 stations, the 2nd at one station, the 4th at twenty-one stations, the 

 5th at seven, and the 1st and 4th were the wettest at one station. 

 There were floods in the early part of the month, some account of 

 which is given as an appendix. 



March. — A very wet month, with snow at the beginning and 

 end, and a large number of wet days. On the 2nd the fall was 

 considerable at twenty-nine stations and very considerable at two, 

 and on the 17th considerable at eight and very considerable at two. 

 The 2nd was the wettest day at thirty-eight stations, the 17th at 

 three, and the 2nd and 1 7th at one station. 



Apeil. — Rainfall a little below the average for the month and 

 on about the usual number of days. A little snow fell during the 

 first week. On no day was there a considerable fall of rain. The 

 16th was the wettest day at ten stations, the 17th at three, the 

 19th at one station, the 21st at one, the 28th at one, the 30th at
