MR. J. F. MILLER ON THE METEOROLOGY OF THE LAFiE 
Note . — The mercurial thermometer got deranged in August, and a duplicate sent 
to supply its place was also found to be separated in the column on its arrival at 
Seathwaite, and consequently useless. Considerable delay took place before the in- 
struments were adjusted, and the registrar did not receive them again till the middle 
of December. From about the middle of August till the 17th of December, the 
maximum was obtained by frequent examination of the spirit thermometer in the 
course of the day; the mean of the maximum for 1850 is in consequence about 1°‘5 
too low. 
The mercurial thermometer, prior to its getting out of order, was considered to be 
nearly free from index error, and the night thermometer has been compared with it 
throughout the scale, and reduced to the mercurial as a standard.

* The results of the thermometers exposed to the sky at Whitehaven and at Seath-waite, are not strictly 
comparable. At Seathwaite, the thermometer on grass is a common spirit thermometer on a boxwood scale. 
Naked thermometers were used for a year or two, but the observations were so frequently interrupted by 
breakage, that it was deemed preferable to employ a less fragile instrument.
