occasions during the year, such falls occurring in the aggregate 
at 27 stations; 15 of the 27 records are from this area, 6 are from 
the neighbourhood of Hitchin and Baldock, 4 are from the valley 
of the Yer, and the other two are contributed by Moor Park and 
Therfield. The heaviest falls of rain seem to have been on the 
high ground between the sources of the Thame and the Bulhourne, 
and in the Bulhourne and Grade valleys.

The total yearly fall ranged from 21*88 inches at the Bed House, 
Ware, to 32*91 inches at Pendley Manor, Tring; and the total 
monthly fall from 0*31 inch at Odsey in September to 5*98 inches 
at Pendley Manor in February. The greatest fall in any one day 
was 1*80 inch at Pendley Manor on the 13th of February. 
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 , f inch very considerable , 1 inch great , 14 inch very 
great , 1^ inch heavy , and If- inch very heavy. There was no excessive 
fall (2 inches). This analysis only applies to the thirty-two stations 
for which I have returns of the daily rainfall, except when the fall 
was the heaviest in the month and reached at least one inch. The 
wettest days which are given in each month are those at forty-four 
stations. 
January.— A very wet month with many days of rain or snow. 
At most stations rain fell every day for the first nine days, and 
there were not two days together without rain or snow after the 
13th. A little snow fell, with rain, on the 14th, and from the 
27th to the 30th. The fall of rain was considerable at ten stations 
on the 1st; and on the 6th it was considerable at fourteen stations,
