The strokes which were originally at an angle in the vertical letters must still have their thickness laid off at right angles. This principle can readily be seen when applied to the Z. In many cases, however, the W for example, this question makes such a minute difference that the thickness of the heavy stroke may be laid off horizontally.
The principle of converting a vertical letter into a slant letter is graphically illustrated in the following diagram (figure 11).
Fig 11.
The letter is not " rolled along, " not tilted over, but the points move horizontally to the right until the original vertical center line assumes a "3 in 8 " slant, that is, until the point A, in the accompanying cut, has moved to the right through a distance of ⅜, of the height of the letter.
With these explanations of the general theory of the slant letter, no difficulties should be encountered.
