Solar Variation and the Weather

WHILE he was visiting the United States at the end of last year, Sir Richard Gregory invited me to contribute to NATURE a general review of the results of the long campaign of the Smithsonian Institution on the variation of the sun, which was instituted by the late secretary, S. P. Langley. Thus far it has accomplished about 40,000 measurements of the solar constant of radiation, involving observations filling about 10,000 days, besides numerous and interesting side researches. A more detailed account of results is expected to appear in the April issue of the Quarterly Journal of the Royal Meteorological Society.
