198 MR. T. HOPKINS ON THE 



by Mr. Millar — they are for the six summer months of 

 1848— 



Inehei. 



Seathwaite, 240 feet above the sarface of the sea,... 68'96 

 Sty-head, 1,290 feet above the surface of the sea,... 60-35 



Here we find no increase in the quantity of rain that falls 

 above 240 feet pf height where the gauge is placed in Sea- 

 thwaite. On the contrary, the quantity is greater there than 

 at Sty-head, 1,050 above it. This fact furnishes rather 

 strong presumptive evidence, that the quantity of rain that 

 is received in a gauge, at any particular elevation, is not 

 proportioned to the height at which the gauge is placed. 



In comparing the quantities of rain that fall at various 

 heights, including great elevations, it is obviously necessary 

 to compare them during the summer months alone, as has 

 been done when comparing Seathwaite and Sty-head Pass; 

 and the facts that are principally relied upon by Mr. Millar, 

 and from which he draws his general conclusions, are the 

 quantities of rain that fell in twenty-one months in 1846 

 and 1847 in six places, namely: — 



Incbes. 



The Valley (Wastdale) ... 160 feet above the sea, 17055 



Sty-head, 1,290 „ 185-74 



SeatoUer, 1,344 „ 180-23 



Sparkling Tarn, 1,900 „ 207-91 



Great Gable, 2,925 „ 136-98 



Sca-fell, 3,166 „ 128-15 



But these facts, although they countenance the hypo- 

 thesis advanced, do not afford conclusive, or even strong, 

 evidence upon the subject. The Valley we see, 160 feet 

 high, has 170*55 inches; whilst SeatoUer, 1,344 feet high, 

 and consequently 1,184 feet higher than the Valley, has 

 only 180*23 inches, not 10 inches more of rain ; whilst 

 Sty-head, 54 feet below SeatoUer, has 5^ inches more of 

 rain than that place. There is another place noticed by 

 Mr. Millar, called Brant Rigg, 500 feet high, between the 

 Valley and Sty-head, which received 12|^ per cent, less of
