| Let the number chosen be | 6 |
| Which doubled is | 12 |
| And 4 added to it, makes | 16 |
| Which multiplied by 5, gives | 80 |
| To which 12 being added, it is | 92 |
| That multiplied by 10, makes | 920 |
| From which deducting 320, remains | 600 |
And by striking off the two cyphers, it becomes the former number 6.
The Camelion Spirit.
Put into a decanter some volatile spirit, in which copper filings have been dissolved, and it will produce a fine blue tincture, if the bottle be stopped the colour will immediately disappear, but when unstopped, it will return.
Three Dice being thrown on a Table, to tell the Number of each of them, and the order in which they stand.
Let the person who has thrown the dice double the number of that next to his left hand, and add five to that sum; then multiply the amount by five and to the product add the number of the middle dice, then let the whole be multiplied by ten, and to that product add the number of the third dice. From the total let there be substracted 250, and the figures of the number that remains will answer to the points of the three dice, as they stand on the table.
Example.
Suppose the points of the three dice thrown on the table to be 4, 6, and 2.
| Then the double of the first die will be | 8 |
| To which add | 5 |
| 13 | |
| 5 | |
| That sum multiplied by 5 will be 65 | 65 |
| To which add the number of the middle dice | 6 |
| 71 | |
| And multiply the sum by 10 | 10 |
| 710 | |
| To that product add the number of the third dice | 2 |
| 712 | |
| Substract | 250 |
| 462 |
The numbers of the dice and the order in which they stand.
