606 Notes on Capt. Shortredes Scheme. [No. 116. 



28. Observe here that only four days of the week begin the hundreds 

 of New Style ; and three days of the week never have that privilege, 

 not for 40 centuries. The years in column/, are all leap years in New 

 Style. This accounts for that arrangement of Capt. Shortrede's scheme, 

 which occupies only 4 of the 7 divisions with N. S. centuries. 



29. About the time of the 40th century, the Vernal Equinox will be 

 1 day nearly in advance of the 20th of March ; in which case if the 

 British Calendar and British Parliament be in existence, it may be 

 found necessary to throw out a day from the Calendar. If the mea- 

 sure be adopted in the year 4000 a. d. then this year will not be a leap 

 year, and as 4000 is a multiple of 400, and consequently falls in column 

 / the year 4000 will begin and end with/ Art. 4 ; the week-days a and c 



will go out and b and g will occupy their place for the next 40 centuries, 

 during which period the hundreds will begin thus : — 

 d b g e 



100 200 300 400 &c. 



Centuries and years and hundredth years will begin a day earlier. 

 By adjusting the "full-century-division one place to the right of 

 for every 40 centuries," according to the directions given in the scheme, 

 a correction will be effected for the current years ; but as the centuries 

 and week-days are in fixed position on the same card, the prescribed 

 adjustment is not effective for the hundredth years or full centuries on 

 the middle card. 



30. It is now time to shew the relation between the week-days of Old 

 and New Style. On the 3d of September 1752, New Style was intro- 

 duced in England, when the 3rd of September was called the 14th (25). 

 Consequently the 14th of September N. S. fell on a certain day in the 

 first week, but the 14th September O. S. fell 11 days after in the 

 second week : therefore the New Style dates may be said to occur i 1 

 week-days, that is, 1 week and 4 days, that is 4 week-days earlier than 

 O. S. dates. 



31. If it should ever happen that a day is rejected from any year 

 by New Style and not by Old Style, then that year in New Style will 

 end 1 day sooner than in Old Style ; and consequently the next year of 

 New Style will be another day earlier than Old Style ; that is 12 days 

 of date or 5 week-days ; and as often as this happens, New Style will be 

 an additional day earlier than Old Style.
