If now you would make a _Gage_ for any number of thin Spaces and Sixth Parts of a thin Space, you must take one thin Space less than the number of thin Spaces proposed, and add . : , - ; according as the number of sixth Parts of a thin Space require; and to those complicated Thicknesses you may file a square Notch on the edge of the thin Plate aforesaid, which shall be a standing Gage or Measure for that number of thin Spaces and sixth Parts of a thin Space. All the Exception against this way of Measuring is, that thin Spaces cast in Metal may be subject to bow, and so their Thicknesses may prove deceitful. But, in Answer to that, I say, you may, if you will, Cast I for two thin Spaces thick, e for three thin Spaces thick, S for four thin Spaces thick, L for five thin Spaces thick, D for six thin Spaces thick, or any other Letters near these several Thicknesses, as you think fit; only remember, or rather, make a Table of the number of thin Spaces that each Letter on the Shank is Cast for. And by complicating the Letters and Points, as aforesaid, you will have any Thickness, either to make a Gage by, or to use otherwise. On the other Edge of the _Face-Gage_ you may file three other Notches, of the same Width with those on the former Edge, for the Long, the Assending, and Short-Letters. But though the two sides of each of these Notches are parallel to each other, yet is not the third side square to them, but hath the same Slope the _Italick_ hath from the _Roman_; as you may see in the Figure at _b b b_. ¶. 6. _Of_ Italick, _and other_ Standing Gages. These _Gages_ are to measure (as aforesaid) the Slope of the _Italick_ Stems, by applying the Top and Bottom of the _Gage_ to the Top and Bottom-Lines of the Letters, and the other Side of the _Gage_ to the Stem: for when the Letter complies with these three sides of the _Gage_ that Letter hath its true Slope. The manner of making these _Gages_ (and indeed all other _Angular Gages_) is thus. Place one Point of a Pair of Steel _Dividers_ upon the thin Plate aforesaid, at the Point _c_ or _d_ (in _Fig._ D in _Plate_ 10.) and with the other Point describe a small fine Arch of a Circle; as, _e f_ or _g h_. In this Arch of the Circle must be set off on the _Gage_ _a_ 110 Degrees, and on the _Gage_ _b_ 70 Degrees, and draw from the Centres _c_ and _d_ two straight Lines through those numbers of Degrees: Then Filing away the Plate between the two Lines, the _Gages_ are finished.
