of Meteorological Obfervations. 239 
numbet of years, we could, with _ tolerable 
accuracy, determine the comparative elevation of 
thofe different places above the level of the fea; 
fome of which, from their gradual rifing, are very 
difficult to afcertain, but which it would not only 
be curious, but highly interefting, to know. 
In the 59th. vol. of the Philofophical Tranfac- 
tions, fome experiments are related, by which it 
appears, that more rain is collected by a gage placed 
on the futface of the earth, than by another fimilar 
gage placed confiderably higher. Mr. Gough's 
ebfervations confirm this fact, fince the quantity of 
rain collected by the gage at Kendal, is confiderably 
greater than the quantity which fell upon Benfon- 
Knott, fituated 320 yards above the level of the 
town. This fact has engaged the attention of 
different philofophers, who have endeavoured to 
account for it, though in a manner not perfe&ly 
fatisfactory. Dr. Percival’s theory * is very 
ingenious, and undoubtedly the circumftances 
mentioned by him have their fhare in the produc- 
tion of this phenomenon, but Mr. Gough’s account 
appears by much the moft philofophical and fatis- 
factory. It appears likewife from his obfervations, - 
that this difference is lefs in fummer than in winter, 
which he accounts for in a very. ingenious manner. 
I am now endeavouring to collect fimilar obfer- 
vations made on the eaftern coaft, and fhould I be 
fuccefsful,
