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 . keywords: clock; day; mean; minutes; right; seconds; sun; time cache: A60474.xml plain text: A60474.txt item: #4 of 4 id: B06166 author: Tompion, Thomas, 1639-1713. title: A table of the equation of days, shewing how much a good pendulum watch ought to be faster or slower than a true sun-dial, every day of the year. date: 1683 words: 1813 flesch: 75 summary: Copies of the texts have been issued variously as SGML (TCP schema; ASCII text with mnemonic sdata character entities); displayable XML (TCP schema; characters represented either as UTF-8 Unicode or text strings within braces); or lossless XML (TEI P5, characters represented either as UTF-8 Unicode or TEI g elements).
