PROP. V. By knowing the Latitude of a Place, and the Suns Declination, to find the Ascensional Difference.
This is the Analogy or Proportion.
As Radius or S. 90°,
To Tc. of the Latitude given,
So is T. of the Suns Declination given,
To the S. of the Ascensional difference required.
☞ Note that if you reduce the degrees, &c. of the Ascensional difference into hours, it will shew you how much the Sun riseth, or setteth before, or after six a Clock, in that Latitude.
