The two figures to the right will denote her age, and the remainder the month of her birth. For example, the amount is 822. She is twenty-two years old, and was born in the eighth month, (August.)

Thus suppose her age to be 17, you will find that number in the first and fifth columns; add the first figures of these two columns. Here is the magic table:
