It may not be impertinent to add, that the barometers at Selborne
stand three-tenths of an inch lower than the barometers at South
Lambeth; whence we may conclude that the former place is about
three hundred feet higher than the latter; and with good reason,
because the streams that rise with us run into the Thames at
Weybridge, and so to London. Of course therefore there must be
lower ground all the way from Selborne to Sough Lambeth; the
distance between which, all the windings and indentings of the
streams considered, cannot be less than an hundred miles. I am,

Letter LXI
To The Honourable Daines Barrington
Since the weather of a district is undoubtedly part of its natural
history, I shall make no further apology for the four following
letters, which will contain many particulars concerning some of the
great frosts and a few respecting some very hot summers, that have
distinguished themselves from the rest during the course of my
observations.
As the frost in January 1768 was, for the small it lasted, the most
severe that we had then known for many years, and was
remarkably injurious to evergreens, some account of its rigour, and
reason of its ravages, may be useful, and not unacceptable to
persons that delight in planting and ornamenting; and may
particularly become a work that professes never to lose sight of
utility.
