these on the whole are considered to be the most convenient. Had 

 the Table been adjusted by 1st March, we should have got rid of all 

 trouble about the 29th of February in leap year, but should have 

 incurred the inconvenience with our present Calendar of reckoning two 

 months of each year as part of the year preceding. — R. S. 



§ 29. Quite true. The adjustment referred to is that by which the 

 full centuries are brought opposite the proper division on the outer 

 card. After 4000 and till 8000, the full century-division is to be ad- 

 justed by the division on the outer card containing 01 instead of that 

 containing 00 as formerly. The current year is then to be read on 

 the outer card as usual. The full century being opposite the 01 divi- 

 sion, that of the 00 will be one place to the left. Hence the full 

 century will commence on a week-day earlier by one than that over 

 the full century on the middle card. This arrangement was preferred 

 to that of shifting the places of the full centuries on the middle card, 

 as hereby the series of full centuries may be continued indefinitely 

 backwards or forwards by uniform common differences. — R. S. 



§ 37. This inference is unwarranted. New Style commenced in 1582, 

 and from that time was used generally in Catholic countries. It was 

 adopted by the Protestants of Germany in I700,and in England 1752. For 

 dates previous to these epochs in the respective countries, this Table 

 or any other as a matter oi fact must be unserviceable for New Style 

 dates ; because such dates did not exist. It is serviceable throughout 

 the whole range of Old Style dates, which still are used in Russia and 

 by the Greek Christians. The year of confusion having occurred 

 before the Christian Era, is out of date. All such cases are provided for 

 generally by the directions for dates before the Christian Era, and for 

 all such, Old Style reckoning, even when fictitious, is perhaps the most 

 convenient. In such cases, however, there is but little occasion to 

 know week-days as a matter of historical reference R. S. 



§ 39. No particular directions are needed. The full century in that 

 case is 0, and at first this digit was inserted in the place now occu- 

 pied by the letters O. S. The difficulty is sufficiently provided for by the 

 remark, that the series of full-centuries may be continued indefinitely.
