The azimuth at the time of greatest eastern or western elongation can be easily computed from the formula: where A denotes the azimuth. p the polar distance. and the latitude of the place. DATE OF GREATEST ELONGATION. To find the time of greatest eastern or western elongation, let denote the hour angle, and and pas before, then we shall have This quantity, Hm, added to or subtracted from the time or transit given above, according to the elongation required, will give the mean time of the greatest elongation at any place whose north latitude is 7. Rules for Foretelling the Weather. ADAPTED FOR USE WITH ANEROID BAROMETERS, A RISING BAROMETER, A RAPID rise indicates unsettled weather. A gradual rise indicates settled weather. A rise with dry air and cold increasing In Summer Indicates A rise with southerly winds indicates fine weather. With dry air and seasonable temperature indicates a continuance of very fine weather. A FALLING BAROMETER. A rapid fall indicates stormy weather. A rapid fall with westerly wind indicates stormy weather from the northward. A fall with a northerly wind indicates storm, with rain and hail in Summer, and snow in Winter. A fall with increased moisture in the air, and heat increasing, indicates wind and rain from the southward. A fall with dry air and cold increasing in Winter indicates snow. A fall after very calm and warm weather indicates rain with squally weather, The barometer rises for northerly winds, including from northwest by north to the eastward for dry, or less wet weather, for less wind, or for more than one of these changes, except on a few occasions, when rain, hail, or snow comes from the northward with strong wind. The barometer falls for southerly wind, Including from southeast by south to the westward, for wet weather, for stronger wind or for more than one of these changes, except on a few occasions, when moderate wind, with rain or snow, comes from the northward. The above printed rules are in use by the Seawanhaka Corinthian Yacht Club of New York. SUNSET COLORS.-A gray, lowering sunset, or one where the sky is green or yellowishgreen, indicates rain. A red sunrise, with clouds lowering later in the morning, also indicates rain. HALO (SUN DOGS). By halo we mean the large circles, or parts of circles, about the sun or moon. A halo occurring after fine weather indicates a storm. CORONA.-By this term we mean the small colored circles frequently seen around the sun or moon. A corona growing smaller indicates rain; growing larger, fair weather. RAINBOWS.-A morning rainbow is regarded as a sign of rain; an evening rainbow of fair weather. SKY COLOR.-A deep-blue color of the sky, even when seen through clouds, indicates fair weather; a growing whiteness, an approaching storm. FOGS.-Fogs indicate settled weather. A morning fog usually breaks away before noon, VISIBILITY.-Unusual clearness of the atmosphere, unusual brightness or twinkling of the stars, indicate rain, FROST.-The first frost and last frost are usually preceded by a temperature very much above the mean.
