Abstract
MY attention having been accidentally directed to this matter, I have made observations for the purpose of comparing the observed duration of sunrise and sunset with the duration computed from geographical position and Nautical Almanac data, and have now seventy-nine complete observations, made mostly with marine horizons on Manila Bay, the China Sea, the open Pacific, Vineyard Sound, and Buzzard's Bay, with a few made with land horizons. The viewpoints have been from sea-beach to 1512 metres elevation.
