1841.] Notes on Capt. Shortredes Scheme. 607 



32. This happens in those years of N. S. which are divisible by 100, but 

 not by 400 ; that is in the years contained in the columns e, c, a, of Table 

 (5). The following centuries begin as many days earlier in New Style 

 than they do in Old Style, as are indicated by the numbers below them. 



It is necessary to keep in mind that, as the intercalary day is 

 thrown out in these years, at the end of February, this suppression of 

 a day does not affect the calculations for the dates and days preceding 

 the 28th of February : it makes those years end sooner, but not begin 

 sooner or later in the week.* 

 Centuries, 17, 18, 19, 20, 21, 22, 23, 24, 25, 2Q, 27, 28, 29, 30. 

 Days, ... 11, 12, 13, 13, 14, 15, 16, 16, 17, 18, 19, 19, 20, 21, &c. 



Consequently the years from 1801 to 1900 inclusive begin 12 days 

 earlier than they do in Old Style, 



The hundreds of New Style advance as below : — 

 Hundredth Years, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29. 



Days, 10, 11, 12, 13, 13, 14, 15, 16, 16, 17, 18, 19, 19. 



Week Days, ... 3, 4, 5, 6, 6, 0, 1, 2, 2, 3, 4, 5, 5, 



33. If New Style be carried back in theory, the preceding arrange- 

 ment will shew that New and Old Style agree in the following hun- 

 dredth years or full centuries. 



Years a. d. 300, 1200, 1300, 2200, 3100, 4000, 4100.t 



34. The year 1841 N. S. began on Friday, therefore the year 1841 

 O. S. began 12 days or 5 week-days later; viz. on Wednesday. The 

 year 1800 N. S. began on Wednesday ; the year 1800 O. S. began 4 

 days later on Sunday. But 1800 O. S. stands in column b of Table (2), 

 consequently b is Sunday, and 1800 N. S. stands in column c. of Table 

 (5) therefore c is Wednesday. Therefore the letters indicating the 

 days of the week have the significations attached below : — 



O. S. Table (2) e Wednesday, 

 d Tuesday, 

 c Monday, 

 b Sunday. 

 a Saturday, 

 g Friday. 

 f Thursday. 



N. S. Table (5) e Friday. 



c Wednesday, 

 a Monday, 

 f Saturday. 



* The note at the foot of p. 35 Cab, Cyc, Chronology of History, "The Style" is 

 partly erroneous. 



t The agreement of 1200 commences on the 28th N. S. 29th O. S. of February of the 

 year 1100, and terminates on the 28th N. S., 29th 0. S. of February of the year 1300.
