The total yearly fall ranged from 24*41 inches at Royston to 
30-76 ins. at Rensworth, and the total monthly fall from 0-73 in. 
at Fan hams Hall, Ware, in November, to 6*86 ins. at Rensworth 
in July. The greatest fall in any one day was 3*76 ins. at High 
Down, Hitchin, on the 12th of July. 
Distribution of Rainfall in each Month. —The nomenclature used 
in the following account of the chief falls of rain is the same as in 
previous reports, falls of at least \ inch being styled considerable , 
f inch very considerable , 1 inch great , If inch very great, 1 \ inch 
heavy , If inch very heavy, and of 2 inches and upwards excessive. 
This analysis only applies to the 23 stations from which I have 
returns of the daily rainfall, except when the fall, being at least 
half an inch, was the maximum in the month.
