The multiples and subdivisions of the several units in the above system are all adapted to the scale of Notation in common use; a circumstance of considerable importance, as it tends greatly to simplify and facilitate calculation. In the division of the circle, however, the duodecimal scale would have answered much better than the decimal. The number, by which the circumference of the circle is expressed, ought not only to be divisible into 4 integral parts, but also into 6; for the sixth part of the circumference, having its chord equal to the radius, naturally falls, in the construction of instruments, and in the computations of Trigonometry, to be expressed by an integral number.
