in the mean temperature alone. With regard to the maximum 
and minimum temperatures, the results here are similar to those 
obtained in other places, the mean daily range being more con- 
tracted, and less than that at the Institution by a difference of 0°.6 
in 1867, and of 1°.5 in 1868. 
Winds.—The direction of the wind, as indicated by the vane 
on the tower of the Abbey Church, has been noted down regu- 
larly, at the same time as the other observations in the Institu- 
tion Gardens, during the decade of years to which all the obser- 
vations relate. But a single daily entry of this kind affords a 
very imperfect idea of the relative frequency of the different 
winds, or of the duration of any particular wind, several changes 
of direction occurring occasionally during the day; whilst it 
gives us no information respecting the force of the wind, or the 
amount of its horizontal motion from one period of time to 
another. These particulars, so important for the full conside- 
ration of the laws of weather and climate, can only be obtained 
by means of an anemometer, which the Institution does not at 
present possess. I do not therefore attach much value to this 
column in our meteorological register, though it may be useful 
and of some interest to put on record such results as it affords. 
Distributing then the winds, as entered in the register, under 
the four heads of N.—E., E.—S., 8.—W., and W.—N., the first 
of these classes embracing the winds from N. and N.E., but not 
those due E.; the second in like manner E. and S.E., but not 
those due S. ; the third S. and S.W.; the fourth W. and N.W. ; 
it appears that by far the most prevalent winds in Bath are those 
from the W.—N. quarter, those next in frequency being the 
instrument in the garden (of course protected from the direct solar rays), a 
little way from the house, being at the same time only 69°.4, a difference of 
more than jwe degrees and a half. On the morning of the 31st, though the 
previous day had not been so intensely hot as in the former case, the same 
thermometer at the hall window, at 9 a.m,, was 72°, the instrument in the 
garden being 64°, a difference of eight degrees.
