## A Person Having Put A Ring An One Of His Fingers To Name The Personthe Hand, the Finger, and the Joint on which it is placed. Let a third person double the number of the order in which he stands who has the ring, and add 5 to that number; then multiply that sum by 5, and to the product add 10. Let him next add 1 to the last number, if the ring be on the right hand, and 2 if on the left, and multiply the whole by 10: to the product of this he must add the number of the finger, (counting the thumb as the first finger,) and multiply the whole again by 10. Let him then add the number of the joint, and, lastly, to the whole join 35. He is then to tell you the amount of the whole, from which you are to subtract 3535, and the remainder will consist of four figures; the first of which will express the rank in which the person stands, the second the hand, (number 1 signifying the right, and 2 the left,) the third number the finger, and the fourth the joint.--For example: Suppose the person who stands the third in order has put the ring upon the second joint of the thumb of his left hand; then, The double of the rank of the third person is 6 To which add 5 11 Multiply the sum by 5 55 To which add 10 And the number of the left hand 2 67 Which being multiplied by 10 670 To which add the number of the thumb 1 671 And multiply again by 10 6710 Then add the number of the joint 2 And lastly the number 35 6747 From which deducting 3535 The remainder is 3212 Of which, as we have said, the 3 denotes the third person, the 2 the left hand, the 1 the thumb, and the last 2 the second joint.
