102 THe WEATHER oF 1905. 
March, and during the prevalence of strong southerly and south- 
westerly winds. I believe this is not an altogether unprecedented 
phenomenon, but it is at least exceedingly rare, so rare that I do 
not myself remember of having observed it during the nearly 
twenty years to which my observations extend. 
With regard to the hygrometrical observations, I have only 
to add that the mean reading of the dry bulb thermometer for the 
year was 48.1 deg., almost exactly the same as the annual mean 
temperature, which is 48.2 deg. And the mean reading of the wet 
bulb was 45.2 deg.—from which the temperature of the dew-point 
was calculated as 41.7 deg., and the relative humidity at 80 
(saturation being equal to 100). This is lower than the average by 
3, the annual mean over a series of years being fully 83, and 
corresponds with the comparative dryness of the year. With 
regard to wind direction, the most prevalent, as usual, was S.W.., 
which blew on 863 days ; the next, W., with 594 days, and N.W., 
with 534. South blew on 20 days, S.E. on 46; N.E. on 363; 
E. on 29; N. on 164; and calm or variable was 183. The sum 
of those with a southerly and westerly direction was 206, and of 
those with a northerly and easterly was 135. 
The Chairman asked how Mr Andson accounted for the 
extraordinary rainfall of 150 inches on the Cumberland hills, and 
also what was the general track of storms visiting the country. 
Mr Andson said that the great rainfall mentioned by the 
president was recorded at a station in the Cumberland hills 
situated four or five hundred feet above sea level, and it was the 
situation in the midst of the Cumberland mountains that 
accounted for the rainfall, as also did the elevation of some parts 
‘in the midst of the Galloway hills, where the fall was 50 or 60 
inches. At the approach of a depression the wind usually backed 
to the south-east, and then veered to the south, south-west, and 
west. 
Dr Maxwell Ross moved a cordial vote of thanks to Mr 
Andson for his valuable contribution. It was specially interesting 
in relation to the state of water supplies and to the river Nith. 
He was much interested to observe that, although in the case of 
the Dumfries observation station the rainfall for 1905 had been 
the lowest that Mr Andson had recorded, yet it was not the lowest 
at some of the other stations. For example, in the case of the
