He lived 77 years, and 7 + 7 = 14. Louis XV. mounted the throne in the same year; he died in 1774, which also bears the stamp of 14, the extremes being 14, and the sum of the means 7 + 7 making 14. Louis XVI. had reigned 14 years when he convoked the States General, which was to bring about the Revolution. The number of years between the assassination of Henry IV. and the dethronement of Louis XVI. is divisible by 14. Louis XVII. died in 1794; the extreme digits of the date are 14, and the first two give his number. The restoration of the Bourbons took place in 1814, also marked by the extremes being 14; also by the sum of the ciphers making 14. The following are other curious calculations made respecting certain French kings. Add the ciphers composing the year of the birth or of the death of some of the kings of the third race, and the result of each sum is the titular number of each prince. Thus:-- Louis IX. was born in 1215; add the four ciphers of this date, and you have IX. Charles VII. was born in 1402; the sum of 1 + 4 + 2 gives VII. Louis XII. was born in 1461; and 1 + 4 + 6 + 1 = XII. Henry IV. died in 1610; and 1 + 6 + 1 = twice IV. Louis XIV. was crowned in 1643; and these four ciphers give XIV. The same king died in 1715; and this date gives also XIV. He was aged 77 years, and again 7 + 7 = 14. Louis XVIII. was born in 1755; add the digits, and you have XVIII. What is remarkable is, that this number 18 is double the number of the king to whom the law first applies, and is triple the number of the kings to whom it has applied. Here is another curious calculation:-- Robespierre fell in 1794; Napoleon in 1815, and Charles X. in 1830. Now, the remarkable fact in connection with these dates is, that the sum of the digits composing them, added to the dates, gives the date of the fall of the successor. Robespierre fell in 1794; 1 + 7 + 9 + 4 = 21, 1794 + 21 = 1815, the date of the fall of Napoleon; 1 + 8 + 1 + 5 = 15, and 1815 + 15 = 1830, the date of the fall of Charles X. There is a singular rule which has been supposed to determine the length of the reigning Pope's life, in the earlier half of a century. Add his number to that of his predecessor, to that add ten, and the result gives the year of his death. Pius VII. succeeded Pius VI.; 6 + 7 = 13; add 10, and the sum is 23. Pius VII. died in 1823. Leo XII. succeeded Pius VII.; 12 + 7 + 10 = 29; and Leo XII. died in 1829. Pius VIII. succeeded Leo XII.; 8 + 12 + 10 = 30; and Pius VIII. died in 1830. However, this calculation does not always apply. Gregory XVI. ought to have died in 1834, but he did not actually vacate his see till 1846. It is also well known that an ancient tradition forbids the hope of any of St. Peter's successors, _pervenire ad annos Petri_; i. e., to reign 25 years. Those who sat longest are
