N. B. For every century a neve folar cycle mu ft: 
be made; becaufe, by the Ad of Parliament* 
for correcting the calendar, every 100th 
year for three centuries is common , and not 
bif extile ; fo that the fame dominical letter 
ftands againft the fame year, in the cycle only 
for 100 years in 'three fucceffive centuries. 
N. B. By a continual addition of 28 to 1700 or 
1756 -j-, we have the firjl year of each folar 
cycle ; and when the firjl year of that cycle 
next after the beginning of any century is 
had, and its dominical letter found, by the 
rules and tables in the ad, the cycle Jor that 
century may be formed , with the dominical 
letters anfwering to each year of it ; where- 
by may be feen on what years of the cycle the 
fame Sunday letter recurs. Thus ; 
Queft. 2. If it was required to find in what years 
between 2200 and 2300 Eafter Day would again 
happen on 2 2d of March ; I find by the hints above, 
that the firjl year of the folar cycle falls on 2204 ; 
and, being leap-year , I find by the rules and tables 
in the ad', that the dominical-letters are AG: from 
thence I conflrud the folar cycle of 28 years* as in 
table 1.
