The numbers, representing an ascending7 series from 6 to 89, with one recurring 6, suggested the possibility of this form of cryptogram having been used. The numbers in the centre suggested a sum, which, when done, would throw some light on the arithmetical puzzle in the centre of the circle by division, subtraction8, or multiplication9.
