To tell by a Watch Dial the Hour when a Person intends to rise.
ОглавлениеThe person is told to set the hand of his watch at any hour he pleases, which hour he tells you; and you add in your mind 12 to it. You then desire him to count privately the number of that addition on the dial, commencing at the next hour to that at which he intends to rise, and including the hour at which he has placed the hand, which will give the answer: for example.
A intends to rise at 6, (this he conceals to himself;) he places the hand at 8, which he tells B, who, in his own mind, adds 12 to 8, which makes twenty. B then tells A to count twenty on the dial, beginning at the next hour to that at which he proposes to rise, which will be 5, and counting backwards, reckoning each hour as one, and including in his addition the number of the hour the hand is placed at, the addition will end at 6, which is the hour proposed; thus,
The hour the hand is placed at is | 8 |
The next hour to that which A intends to rise at is 5, which counts for | 1 |
Count back the hours from 5, and reckon them at 1 each, there will be 11 hours, viz., 4, 3, 2, 1, 12, 11, 10, 9, 8, 7, 6 | 11 |
