     summary: However upon the account of the innocence of my end in publishing this Book , and that it was written only as the ha●●less ( I may add also the vertuous ) sport of leisure hours ; I think my self excusable to God and the World , for the expence of so much time , in a subject different from my Profession . What Mr. Oughtred had wrapt up in ●his Algebraick obscure Characters , was afterwards put into plainer Language ▪ by that excellent Mathematician Sir Jon. Moor , with some additions of his own ; which you have in his Math. Compend .

     summary: All which Irregularities , or difference in Right Ascension , proceed from two principal Causes : 1. From the different Positions : And , 2. From the different Centres of those Orbs in which , and according to which the Sun and Earth do move ; from whence arises a natural necessity , that between two such regular and equal Motions , whose Position is thus oblique , those appearing differences should still arise ; for though both Sun and Earth , the one in his annual the other in it's diurnal Revolutions , be rationally supposed to be regular and equal in their own Motions ; yet in regard of the different Positions of their Spheres , the Right Ascensions that are made by them cannot be equal ; it being impossible that the Sun , when near Aries and Libra , where he moves cross the Equinoctial , should then in any particular number of days make so great an alteration in Right Ascension , as he must do near the two Tropicks , where both Equinoctial and Ecliptick run paralel one to the other ; and accordingly by the best Tables of Right Ascension , 't is found that the Right Ascensions of 10 daies motion of the Sun near the Tropick of Capricorn , shall arise to above 11 degrees 30 minutes , whereas that of the same number of daies near the Equinoctial Point of Aries shall scarcely amount to 9 degrees . Since therefore there is no tolerable exactness in thus adjusting Clocks to the Sun it self , because being thus adjusted at times when daies are either shortest or longest , their gaining or losing will be the more extream in the contrary parts of the year : for Example ; Clocks adjusted to the Sun in March shall upon most daies in December gain almost 50 Seconds , which in the Months time shall amount to near half an hour ; and on the contrary , if adjusted to go true with the Sun in December , it shall in March lose the same time , and so for any other , according as daies do differ in length .
