How to Work the Oraculum
Make marks in four lines, one under another, in the following manner, making more or less in each line, according to your fancy:
Then reckon the number of marks in each line, and, if it be odd, mark down one dot; if even, two dots. If there be more than nine marks, reckon the surplus ones over that number only, viz.:
| The number of marks in the first line of the foregoing are odd; therefore make one mark, thus | * |
| In the second, even, so make two, thus | * * |
| In the third, odd again, make one mark only | * |
| In the fourth, even again, two marks | * * |
