ON THE QUANTITIES OF RAIN AT YORK. 
179 
Occasional remarks may be made on approach to perpen¬ 
dicularity of rain ; showery or continued rain; size of drops at 
the different stations ; hail, snow, &c. The situations chosen 
for the experiment should be in open, plain countries, because 
the influence of the form of undulated ground is extremely un¬ 
certain : stations should be selected on opposite sides of the 
island, as well as in the interior: the central plains of Ireland, 
and some parts of Scotland, offer excellent points. The ele¬ 
vations of the upper stations above the ground ought to be 
nearly the same at all the places of experiment, and the highest 
need not exceed 100 feet, as the following state of results, ob¬ 
tained by the care of my friend Mr. W. D. Littledale, at Bolton 
Park in Craven, will prove.
