In the above example, there being only one 9 in 17, this gives us 4, which added to 3 produces the number thought of--7. When even simply add 4 for every 9 in remainder. HOW TO TELL THE AGE OF A PERSON. Tell a person to write down the figure which represents the day of the week on which he was born;--thus, 1 for Sunday, 2 for Monday, and so on; next, the figure for the month--1 for January, 2 for February, &c.; then the date of the month; now tell him to multiply the number thus formed by 2, add 5, multiply by 50, and then to add his age, and from this sum to subtract 365; now you ask him for the remainder, to which you _secretly_ add 115. The result will be:--The first figure, the day of the week; the next, the month in the year; the next, the date of the month; and the last, the age in years. Example: A person was born on Wednesday, 11th June, 1863. Write 4, as Wednesday is 4th day of the week. " 6, as June is 6th month of year. " 11, as that is the date given, 11th June. The figures then are-- 4611 2 ---- 9222 5 ---- 9227 50 ------ 461350 35 Age ------ 461385 365 ------ 461020 115 -------- 4-6-11-35 A GOOD FIGURE TRICK. Tell a person to set down a sum of money less than £12, in which the pounds exceed the pence; next to reverse this amount, making pence pounds, etc., and to subtract the one from the other, then set beneath the result itself reversed, adding the last two lines together, when you will tell him the result, which will _always_ be £12 18s. 11d. Example: £10 8 7 7 8 10 -------- 2 19 9 9 19 2 -------- £12 18 11 If the performer be blindfolded the trick looks very mystifying; he should not, however, repeat it, for many would soon discover the secret, but as the peculiarity is not confined to money, other illustrations can be given if required--for instance--if a number of yds., ft. and inches (less than 12 yds.) be operated on, the final answer will always be 12 yds. 1 ft. 11 inches; and if a number of cwts., qrs. and lbs. (less than 28 cwts.) be chosen, the answer will always be 28 cwts. 2 qrs. 27 lbs. “Girls” and “Boys.” At a school examination, the inspector set the girls to write an essay on “Boys” and the boys to write one on “Girls.” The following was handed in by a girl of 12:--
