The apparent or femhg Magnitude is meafured by the Optick Angle. See Optick *ngle. ,

The greateft apparent Diameter of the Sun, according to Caffwi, is 52', , o", and the leaft 31', 38".— According to delaHire, the greateft is3a',43"j and the leaft 31,38'! The greateft apparent Diameter ot the Moon, ac- cording to Kepler, is 52', 44"; and ihe leaft 30', 00"— - u And according to de la Hire, the one is 33', 50; and tho other 29', 30". See Sun and Moon.
The apparent Diameter of Saturn's Ring, according to Huygexs, is 1', t8", Vhen ieaft. See Saturn.
The apparent Isiameters of the other 'Planets, fee uniit the Article Diameter. .
If the Diftances of any two remote very Objects, for ex- ample, two Planets, be equal, their true Diameters ate proportional to the apparent ones; and if the apparent Diameters be equal, the true Diameters will be as the Di- ftanccs from the Eye Hence, when neither the Di- ftanccs nor the apparent Diameters are equal, the true Diameters will be in a Ratio compounded of the direct B.atio of the Diftances, and of the direct Ratio of therfj>- pareut Diameters.
There is a further very obfervable Difference between the apparent Magnitudes or Diameters of the Sun and Moon when in the Horizon, from what they are in the Meridian; the reafon whereof has long perplexed the Phiiofopners.
