years, following a December which was also, with one exception, the
coldest for twenty-one years.' He gives an abstract of the temperatures
(both maximum and minimum) for November, December, and January during
the last twenty-one years, from which it appears:--
1. That the average _maximum_ temperature of November was the lowest
during the period with two exceptions, that of December the lowest with
one exception, and that of January the lowest of the whole period.
2. That the average _minimum_ of November was the lowest during the
period with four exceptions, that of December the lowest with one
exception, and that of January the lowest.
3. That the mean temperature of the three months was not only five
degrees below the average, but also lower than in any previous year out
of the twenty-one.
On the whole, the winter of 1878-79 must be regarded as the coldest we
have had during at least the last score of years, and probably during
twice that time. It was not characterised by exceptionally severe short
periods of intense cold, like those which occurred during the winters
of 1854-55, 1855-56, and 1860-61; but it has been surpassed by few
winters during the last two centuries for constant low temperature and
long-continued moderate frost. During the last ninety years there have
been only four winters matching that of 1878-79 in these respects.

Since the preceding pages were written the weather record for February
1879 has been completed. Like the three preceding months, February
showed a mean temperature below the average, though the deficit was not
quite so great as in those months. The following table, drawn out by
Mr. Plant, shows the mean temperature at Moseley for four winter months
of 1878-79, and the average temperature for those months at Moseley
during the last twenty years:--
1878-79

November 37.0
December 31.0
