By the climate of a
district is meant its average weather. This is largely determined by
its temperature and its rainfall, and very much depends on its
altitude and its distance from, or proximity to, the sea. No British
county is large enough to have a distinctive climate of its own:
each shares in that of the geographical region to which it belongs.
The following table,
compiled from the late Dr Buchanís papers, shows the mean
temperature over forty years ending 1895 of several stations in
Forfarshire; and, when allowance has been made for local conditions,
it illustrates how uniformly temperature varies with altitude.
