Abstract
THE criticism by Mr. Phillips, Superintendent of the Falmouth Observatory, is more a matter for the Meteorological Office than for me. In my article it is stated clearly that the sunshine records are taken from the “Book of Normals”, published by the Meteorological Office. Exception is taken by Mr. Phillips to the paragraph he quotes from the article, where it is stated that the values quoted are taken from a “Book of Normals” (M.O. 236, Section 2) giving seasonal normals for several districts; in this the Meteorological Office has combined south-west England and south Wales in one normal. I am not at all sure that I agree with Mr. Phillips in thinking that the Meteorological Office should have separated south-west England and south Wales. I agree practically in the results obtained if these two parts are separated, and I will accept Mr. Phillips' sunshine value 4.53 hours for the year for south-west England in which observations are taken for Newquay, Cullompton, Plymouth, and Falmouth. Taking all the stations as used by the Meteorological Office for the normal for south-east England, I obtain for the year 4.47 hours a day, in good agreement with 4.49 hours given by Mr. Phillips; this value is obtained from 9 stations. By omitting observations from Kew and Marlborough, and using the remaining 7 stations, the normal for south-east England is 4.62 hours, which is a greater duration than the normal for southwest England.
