Let the number chosen be6
Which doubled is12
And 4 added to it, makes16
Which multiplied by 5, gives80
To which 12 being added, it is92
That multiplied by 10, makes920
From which deducting 320, remains600

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 be8
To which add5
13
5
That sum multiplied by 5 will be 6565
To which add the number of the middle dice6
71
And multiply the sum by 1010
710
To that product add the number of the third dice2
712
