The wheels may be varied in many ways,and made attractive by using colored VI. A change from the wheel, yet practically the same thing, is a column of figures written on the g board, embraced in 3 bracket, at whose point 3 are figures, preceded by signs which tell what 9 is required. This may include giving the first 5 and second terms to find the third, or the first 4 and third to find the second, or the second and 2 third to find the first term. Grades II. and III. g VII.
