LONDON.
Royal Meteorological Society, December 15.-Major H. G. Lyons, president, in the chair.-F. J. Brodie: The incidence of bright sunshine over the United Kingdom during the thirty years 1881-1910. The author described the steady increase in the use of sunshine recorders from the somewhat crude type invented by Mr. J. F. Campbell in the early part of last century to the improved pattern of Sir George Stokes of 1879, which has remained in use with very slight modification to the present day. The paper is based on figures taken from appendix iv. of the Weekly Weather Report for 1913, published by the Meteorological Office, and the maps which have been constructed differ somewhat in detail from those appearing in the official volume. The author dealt with the prevalence of sunshine, both by the seasons in their usual grouping, and annually. He also referred to the average number of sunny days at Greenwich and Falmouth, and to the loss of sunshine recorded in London and other large manufacturing centres. He showed that the abatement of the smoke evil tended to an increased record of sunshine, and placed o the large towns more on a footing of equality with the urban districts.-Dr. W. Galloway: Remarkable cloud phenomena. The author described the curious and rapid changes which took place in a small portion of a thundercloud, witnessed on July 31 last year near Ormesby Broad, Norfolk. The phenomena pointed to the occurrence of electrical discharges, but neither rain, thunder, or lightning occurred.
