which there mud be fomc little Variation made in 
the four laft Precepts or Rules ; but it would be to 
little Purpofe now, to attempt the framing of a new 
Set of Rules for fo diftant a Time. 
The Gregoria?is have chofen to make life of the 
Epacfs to determine the Days of the New Moons, 
and follow pretty nearly the Rules preferibed above; 
except that they order the Epatts to have an ad- 
ditional Augmentation of an Unit eight times in 
2 yoo Years, beginning with the Year 1800, as at the 
End of 400 Years; to which 400 Years if there be 
added three times feven hundred, or 2100 Years, the 
Period of 25-00 Years will be completed in the Year 
3903. After which they do not make their extra- 
ordinary Augmentation of an Unit in the Epafts, till 
at the End of another Term of 400 Years ; which de- 
fers that Augmentation from the Year 4200 to the 
Year 4300. And this is the Reafon that the Rules 
above deliver'd will require a Variation in the Year 
4200; whereas it is dirc&ed in this Paper that the 
Epa&s fhould be augmented, or (which is the fame 
thing) the Golden Numbers be let back in the Ca- 
lendar nine times in 2800 Years. This arifes from the 
Gregorians fuppofing, that the Difference betwixt 19 
Solar and as many Lunar Years would not amount to 
a whole Day in lei’s than 312 Years and a half; 
whereas it has appeared above, that it would amount 
to a whole Day in 310.7 Years. But although the 
Rule preferibed in this Paper comes much nearer to 
the Truth, yet the Error in either Cafe is very incon- 
Ederable, being fo fmall as not to amount to a whole 
Day in many thoufand Years; and therefore is not 
worth regarding.
