And thus we see the account established upon the arise or descent of the stars can be no reasonable rule unto distant Nations at all, and by reason of their retrogression but temporary unto any one. Nor must these respective expressions be entertained in absolute considerations; for so distinct is the relation, and so artificial the habitude of this inferiour globe unto the superiour, and even of one thing in each unto the other, that general rules are dangerous, and applications most safe that run with security of circumstance. Which rightly to effect, is beyond the subtlety of sense, and requires the artifice of reason. CHAPTER IV Of some computation of days and deductions of one part of the year unto another. [Sidenote: _That the days decrease and increase unequally._] Fourthly, There are certain vulgar opinions concerning days of the year, and conclusions popularly deduced from certain days of the moneth: men commonly believing the days increase and decrease equally in the whole year: which notwithstanding is very repugnant unto truth. For they increase in the moneth of March, almost as much as in the two moneths of January and February: and decrease as much in September, as they do in July and August. For the days increase or decrease according to the declination of the Sun, that is, its deviation Northward or Southward from the Æquator. Now this digression is not equal but near the Æquinoxial intersections, it is right and greater, near the Solstices more oblique and lesser. So from the eleventh of March the vernal Æquinox, unto the eleventh of April the Sun declineth to the North twelve degrees; from the eleventh of April unto the eleventh of May but eight, from thence unto the fifteenth of June, or the Summer Solstice but three and a half: all which make twenty two degrees and an half, the greatest declination of the Sun.
