402 A year's weather. 



tliormometer registered seven degrees of frost, yet tlie mean 

 temperature was somewhat high. The thermometers read 60 

 degrees on two or three days ir the shade ; so that taking 

 the mean of the daily monthly heat and the nightly 

 monthly cold the mean temperature for the month was 48-5 

 degrees. The range of temperature was 14-7 degrees. The 

 barometer stood its highest on the 28th, 30-50 and its 

 lowest on the 6th, 29-50 inches, a monthly range of one inch. 

 We had fog on the 10th and 24th. The rain fell on 19 days, 

 the chief downpours being on the 4th, 18th, and 25th, when 1-84 

 of the month's rainfall of 3-11 inches was registered. Mr. 

 Davey gives me the rainfall at Ponsanooth as 4-17 inches, so 

 that in Kennal Vale the month has been somewhat dry.

Mr. Morris, of Truro, gave me a record of a Garden White 

 butterfly late in November. It was a sign of the mild season. 

 The appearance, often in noticeable numbers, of certain of our 

 common butterflies in late autumn is worth a passing word. 

 The geologist regards such a form of butterfly as a living type, 

 speaking to him, like an erratic or an ice-scratched boulder, of 

 the Ice Age, when nearly the whole of Europe lay under glacial 

 ice. A Garden White butterfly hatched in autumn — not a 

 hybernating summer specimen — differs in colour from what it
