On the Climate of Strathpeffer Spa. — 43 
thermometer registered .79°°8, and the lowest was 12°, on 
20th February 1885. The absolute highest and lowest read- 
ings in each year are given in Table II., in comparison with 
the Royal Observatory (London). It is a striking fact that 
in three out of six years the minimum readings were lower 
in the neighbourhood of London than at the Spa, the most 
remarkable case being 1890, the last year of the series. The 
mean of the lowest readings is precisely the same for the 
two stations. On the other hand, the mean of the highest 
(summer) readings is 75°4 at Strathpeffer against 88°:2 at 
Greenwich. It follows that the range between the extreme 
temperatures of winter and summer averages about 13° 
less at Strathpeffer than at Greenwich, and this difference is 
almost wholly due to the more temperate climate of the 
summer. .

Table III. shows the seasonal distribution of temperature, 
which is a matter of especial importance at a health resort. 
It is observable that the swnvmer is, on the average, six and 
a half degrees cooler at Strathpeffer than at Greenwich. The 
mean high day temperatures of the several summer months 
and the mean of the low night temperatures are given in 
the first table. Their difference represents the mean daily 
range, which is perhaps a more important element of climate
