can remember; for if there had been any Decrease, which is the thing in Question, it must have been very visible even to the naked Eye.  The Reason of this is very evident, because the Distance of six Miles renders the Observation much more plain and accurate, than can possibly be taken by the nicest Instrument ever yet invented: For what Proportion does six feet bear to six Miles?  It is as one to 5280.  This I think leaves no doubt of the Certainty and Conclusiveness of this Method.  But to put this Matter farther out of Doubt, I shall make [[insert]] it [[/insert]] appear from the Observations of the most expert Astrono-mers, that the Sun's greatest Inclination has Continu'd invariable for this 150 years past. 
   I believe the Observations of [[underline]] Tycho Brahe [[/underline]] are liable to least Objections of any Astrono-mer of his Time; he determined the Lati-tude of [[underline]] Uraniburgh [[/underline]] to be 55 degrees 54'30"; hence the Altitude of the Equator 34 degrees 5'30"; the greatest Meridian Altitude at the Summer Solstice 57 degrees 35':  From which the [[underline]] Flamste-dian Refraction [[/underline]] being deducted, leaves the true Height of the Sun 57 degrees 34'33"; from this substract the Height of the Equator, there will remain the greatest Obliquity of the Ecliptick 23 degrees 29'3":
   Then again at the Winter Solstice, The Alt. of the Sun [[underline]] Dec. [[/underline]] 11. was 10 degrees 41'10". 
 Refraction substract _ _ _ _ 4'15" 
 from the Sun's true Alt. _ _ 10 degrees 36'55"
 Which substracted from the Alt. of the Equator  34 degrees 5'40"
