Smithsonian miscellaneous collections . departures at Buenos Aires. have led him to the conclusion that the weather as distinguished fromthe climate is governed by variations of the sun and would be predict-able both qualitatively and quantitatively if we had daily accuratedeterminations of the solar variation. If this be true, we stand, itseems to me, on the threshold of a very important research in meteorol-ogy. What is needed is the establishment of sufficient stations forobserving solar radiation, in order that, by combining the results ofall of them, well-founded mean solar radiation measurements may beavailable every day in the year, and for a sufficient succession ofyears, so that quantitative studies of the dependence of weather con-ditions on solar variations similar to those of Mr. Clayton may beadvantageously pursued.
