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.
