8. Tails of Letters, is a Stroak proceeding from the Right-Hand Side of the Stem, in the Foot-Line; as a d t u: and most _Italick_ Lower-Case Letters have Tails: As also have most Swash-Letters. But several of their Tails reach down to the Bottom-Line. 9. Swash-Letters are _Italick_ Capitals; as you see in _Plate_ 15. Thus much of _Letter-Cutting_. The next _Exercises_ shall (God willing) be upon _Making Matrices_, _Making Molds_, _Casting and Dressing of Letters_, &c. _FINIS._ ADVERTISEMENT.

THe _Steel-Punches_ being thus finish’d, as afore was shewed, they are to be sunk or struck into pieces of _Copper_, about an Inch and an half long, and one quarter of an Inch deep; but the thickness not assignable, because of the different thicknesses in Letters, as was shewed in §. 2. and shall further be shewed, when I come to the sinking and justifying of _Matrices_. But before these _Punches_ are sunk into _Copper_, the _Letter-Founder_ must provide a _Mold_ to justifie the _Matrices_ by: And therefore it is proper that I describe this _Mold_ to you before I proceed any farther. I have given you in Plate 18. at A, the Draft of one side or half of the _Mold_; and in Plate 19. at B, its Match, or other half, which I shall in general thus describe.
