The annual Mean Temperature of Strathpeffer Spa is 45°-4, 
that is to say 3°°5 below that of London for the same period. 
Among the neighbouring meteorological stations, Culloden, 
about fifteen miles to the south-east of the Spa, has (for the 
forty years, 1841-80) a mean temperature of 46°°6; Dunrobin, 
to the north-east (1857-80), 46°4; Wick, for the same 
period, 46°0; and Aberdeen, 46°°5. It is quite probable 
that more extended observations will show a higher mean 
temperature for Strathpeffer, inasmuch as some recent years 
have been decidedly colder than the average. The warmest 
year of this short series was, 1889 (46°°5), and the coldest, 
1886 (44°3). The highest shade temperature of the six 
years was recorded on the 18th June 1887, when the
