BY the help of these 2 Tables you may know at what hour a● all those stars both rise, set, and come to the Meridian. Th●● the Sun's right Ascension, and subtract it out of the stars Ascensi●● you shall find in the second Column in the first Table, and you 〈◊〉 their rising, setting, and southing as it is there set down: but 〈◊〉 cannot make subtraction, then add 24 to the stars Ascension; remainder shall be the true rising, setting or southing of the af●● stars. Note that if after the subtraction be made there remains 〈◊〉 then 12 hours, subtract 12 out of it, and the remainder is the N●● Example. Upon the 14 of April, I desire to know when all those stars th● and south. First I find the Sun's right Ascension to be 2 how. 〈◊〉 min. and then I come to the Table of the stars, and right against cida Corona, the first star in the Catalogue or Table I find 8. m●● which I add 24 hours, and it is 24. ho. 8. m. out of which I su●● 2. hour and 9 min. and there remains 21 hours, and 59 min. b●● this is more than 12. I also cast away 12. then there remains 9● and 59 min before noon, at which time Lucida Corona sets: 〈◊〉 need not cast away 12. then it is before midnight, otherways midnight. And thus you must do for all those stars whose Ascen●● less than the Suns. But if when the stars right Ascension is most only subtract the Sun's Ascension out of it, and you have your 〈◊〉 I find Arcturus rifing upon the 20 of January in the evening, a●● fire to know to hear of the night, the same day the Sun's righ● tension is 20, hou. 54. m. I find against Arcturus setting 6 hou● 0. m. to which I add 24. hours, and the sum is 30. hou● 〈◊〉 which I subtract 20, hou. 54. m. there remains 9 ho. and 6. mi. th●● hour of the night. Thus by knowing the hour of the night, yo● know the stars by observing on what point of the Compass th● and set on. FINIS.
