Second Buchan Cold Spell April 11–14.—Of the six ‘cold spells’ enumerated by Dr. A. Buchan, the second, April 11–14, receives the least support from either fact or folk-lore. There appears to be no popular saying associating these days with a fall of temperature, and the average daily temperatures at Greenwich from 1841 until 1930 do not reveal any marked cold period in April. An examination of the figures for the individual years at Kew Observatory from 1881 until 1923 showed that April 11–14 had been more often above the temperature to be expected at this season than below it. A different series of years might give a different result, but the inference is clear that Buchan's second cold spell has no real existence in London.
