I was informed by some old residents that, during a period of thirty years, a piece of water in the vicinity of Penzance was in a fit condition for skating only four times, viz. in 1788, 1794, 1814, and 1819.

From Mr. Giddy, sen.'s tables, it appears that the mean number of days on which thunder has been heard, annually, is only two and a half, and the greatest number of days in any one year is only seven.
