yet, however deficient either of them may be, I am obliged, 
through neceffity, to take up their dates and proceed as follows : 
GENERAL OPERATION. 
1. From 1745 take 1657, the remainder is 88 years; divide 
18 degrees, reduced to minutes, viz. 1080 by 88, the quotient is 
12 minutes 16 feconds. 
2. From 1751 take 1657, the remainder is g4 years; divide 
19 degrees, reduced to minutes, viz. 1140 by g4, the quotient is 
12 minues eight feconds nearly. 
3. From 1772 take 1657, the remainder is 115 years; divide 
the minutes in 23 degrees 30 minutes, viz..J410 by 115, the quo- 
tient is 12 minutes 16 feconds nearly. 
4. From 1786 take 1657, the remainder is 129; divide 26 
degrees 21 minutes, reduced to minutes, viz. 1581 by 129, the 
quotient is 12 minutes 16 feconds nearly. 
5. Lasrry, from 1790 take 1657, the remainder is 133; 
divide the minutes in 27 degrees 15 minutes, viz. 1635 by 133, 
the quotient is 12 minutes 18 feconds nearly. 
THe intermediate dates being compared (except the two firft, 
which can be accounted for) will exhibit the fame numbers nearly. 
“Any fmall difference, arifing from a comparifon of the interme- 
diate dates, fhould be attributed to a want of attention to the 
annual
