TAKE your Compasses and extend from I in the Eye of the Volute, to the 
greatest Extent, and sweep with them a Quarter of a Circle; then holding
still in the Point where the Compasses ended the Quarter Circle, bring the
other Point of the Compasses to 2 in the Eye of the Volute; there sweep another
Quarter of a Circle, still holding your Compasses in that Point; bring the
other 
Point of your Compasses to 3 in the Eye of the Volute, and sweep another
Quarter 
of a Circle, then hold your Compasses in that Point, and bring the other
Point of 
your Compasses to 4 in the Eye of the Volute, then sweep the other Quarter;
 so 
by this Means you will complete one Round of the Volute: Then proceed in
the 
same manner from 4, to 5, 6, 7, and so on to 12.  Take Notice of the Eye
of 
the Volute at large, and observe to divide each Division into three equal
Parts, as 
is done betwixt 2 and 6, and let the Point of your Compass be placed in the
Points 
c, d, f, &c. to diminish the Fillet of the Volute.
