METEOROLOGICAL OBSERVATIONS ON BEN NEVIS. 169 
The maximum temperature at Fort William was 75°-0 on June 2, and 
at the top 59°-9 on September 9 ; where on June 25, 59°-8 was recorded. 
The minimum temperature was, at Fort William 8°:9 on February 11, 
and on January 28 9°-0 was recorded ; and at the top 1°8 on February 7. 
This is the lowest minimum temperature yet recorded at the Fort William 
Observatory ; and the above minimum, 1°°8, at the top of the mountain, is 
the lowest there, with the exception of the previous year, when tempera- 
ture fell to 0°°7. The minimum on the top fell below freezing each 
month. 
As regards extremes of temperature, the difference between the 
maxima was greater in July, when it was 21°-0, and least in February, 
when it was only 9°°5 ; and the difference between the minima greatest 
in April, when it was 18°-3, and least in January, when it was only 3°70. 
The registrations of the sunshine recorder at the top show 695 hours 
out of a possible 4,470 hours, being 115 hours fewer than in 1894. This 
equals 16 per cent. of the possible sunshine. The maximum was 149 hours 
in June, and the minimum 3 hours in December, being, along with January 
of the previous year, the lowest hitherto recorded in any month, except 
in December 1893, when there was only 1 hour of sunshine. At Fort 
William the number for the year was 1,132 hours, or 28 hours fewer 
than in 1894. The largest number was 208 hours in June, and the least 
& hours in December. As the number of hours of possible sunshine at 
Fort William Observatory is 3,497 hours, the sunshine of 1895 was 
32 per cent. of the possible number of hours. 
In Table V. are enumerated for each month the lowest hygrometrie 
observations :—

Of these lowest monthly humidities the lowest occurred on February 
11, when the dew-point fell to —25°-8, the elastic force of vapour to 
0-011 inch, and the humidity to 13. On the other hand, in August no 
low humidities occurred, the lowest in this month being 80, a month 
which stands out as being characterised by unrelieved high humidities 
throughout. In this month the hours of sunshine were 25, which is the 
lowest yet recorded in August, except in 1889, when only 9 hours 
occurred ; and the amount of cloud was very large, being exceeded only 
by the August of 1889. At the Ben Nevis Observatory the percentage 
of cloud covering the sky was, on the mean of the year, 82, being 2 per 
cent. less than the mean of previous years. The variation among the 
months was unusually large, the lowest being 60 per cent. in February, 
~and the highest 95 per cent. in March, July, and December. At Fort 
William the annual mean was 71 per cent., the lowest being 45 per cent. 
in February, and the highest 87 per cent. in July and August. The mean 
rain-band (scale 0-8) observation at the top was 2°3 for the year, the
