MR. J. F. MILLER ON THE METEOROLOGY OF THE LAKE 
The Mountain Gauges . — The phenomena exhibited by the mountain gauges in the 
year 1850, do not seem to call for any particular comment, as the results are very 
generally in accordance with the deductions embodied in former papers which have 
appeared in the Transactions of the Royal Society; and at the present time I am 
more anxious to eliminate new facts and to accumulate a mass of accurate observa- 
tions and well-digested results made and obtained both in normal and abnormal 
seasons and under various modifying circumstances, than to theorize upon or draw 
from them inferences or conclusions which extended experience may modify, con- 
tradict or destroy. The following Table shows the excess or deficiency per cent, of 
the principal mountain gauges over or under the quantity of rain received by the 
adjacent valley of Wastdale, both in the summer and winter months, in each year 
since the instruments were erected in 1 846. 
The positive sign signifies that the quantity is greater, and the negative sign that 
it is less than the fall in the valley in the same period.

The remarkable deficiency in the per-centage of rain both in the summer and winter 
months of 1849, is accounted for by the abnormal and relatively excessive fall of rain 
in the Vale of Wastdale in that year, as explained in my last report on the meteorology 
* The per-centages in 1846 and 1847, show the mean of the two years, which were tabulated together.
