In like manner, you may measure any Angle in the Drafts of Letters, by describing a small Arch on the Angular Point, and an Arch of the same Radius on the Centre of your divided Circle: For then, placing one Foot of your Compasses at the Intersection of the small Arch with either of the straight Lines proceeding from the Angle in the Draft, and extending the other Foot to the Intersection of the small Arch, with the other straight Line that proceeds from the Angle, you have between the Feet of your Compasses, the Width of the Angle; and by placing one Foot of your Compasses at the Intersection of any of the straight Lines that proceed from the Centre of the divided Circle, and the small Arch you made on it, and making a Mark where the other Foot of your Compasses falls in the said small Arch, you may, by a straight Ruler laid on the Centre of the divided Circle, and the Mark on the small Arch, see in the Limb of the Circle the number of Degrees contained between the Diametral, or straight Line and the Mark. If you have already a dividing-Plate of 360 Degrees, of a larger Radius than the Arch on your _Gage_, you may save your self the labour of dividing a Circle (as aforesaid,) and work by your dividing-Plate as you were directed to do with the Circle that I shewed you to divide. In these Documents I have exposed my self to a double Censure; First, of _Geometricians_: Secondly, of _Letter-Cutters_. _Geometricians_ will censure me for writing anew that which almost every young Beginner knows: And _Letter-Cutters_ will censure me for proposing a Rule for that which they dare pretend they can do without Rule. To the _Geometricians_ I cross the Cudgels: yet I writ this not to them; and I doubt I have written superfluously to _Letter-Cutters_, because I think few of them either will or care to take pains to understand these small Rudiments of _Geometry_. If they do, and be ingenious, they will thank me for discovering this Help in their own Way, which few of them know. For by this Rule they will not only make Letters truer, but also quicker, and with less care; because they shall never need to stamp their _Counter-Punch_ in Lead, to see how it pleases them; which they do many times, before they like their _Counter-Punch_, (be it of A _A_ V v W w _V_ _W_, and several other Letters) and at last finish their _Counter-Punch_ but with a good Opinion they have that it may do well, though they frequently see it does not in many Angular Letters on different Bodies Cut by the same Hand. And were _Letter-Cutting_ brought to so common Practice as _Joynery_, _Cabinet-making_, or _Mathematical Instrument-making_, every young Beginner should then be taught by Rules, as they of these Trades are; because _Letter-Cutting_ depends as much upon Rule and Compass as any other Trade does.
