g. Let D — 15 ; the reft as before. Then' 
ftnce ^ 9 = D = 1 5 ; therefore d = 6, and 
e — 5> as before ; and 28x2x1 6 = 62 5 and 
62 d- 532 x 4 = 219a. This cyclar number will 
not do, for the fame reafon as before. 
4. Let D = 26 ; the reft as before. Then 
d -j- 9 =s 26 ; therefore d — 17, and e = 5, 
as before; and 28 X 2 X 12 + 17=682; and 
689 4- 532 x 3 — 2285 ; and this is the only year 
that will anfwer the queftion ; becaufe it has 6 for its 
golden number, and D for its dominical letter. 
Whence we may conclude, that after A. D. 1761,.. 
there will not be fo long a Trinity-vacation again till 
1818; and after that year, the like will not happea 
till 2285,
