Imman. Joh. Gerh. Schellers ausführliche lateinische Sprachlehre oder sogenannte Grammatik

At the very beginning of the chapter “Italics, small capitals… [etc.]”, of the book The Form of the Book, Tschichold comments on typographic differentiation in scientific books, and uses the case of a Latin grammar in German to illustrate a good example of the use of various typefaces in a text, to create an illuminating contrast. Here’s a passage from the English edition:

There were, and are, always publications whose text will benefit and become more lucid and comprehensive if some manner of type differentiation is applied. We cannot help but envy Immanuel Scheller’s setting of the Ausführliche lateinische Sprachlehre (Comprehensive Latin Grammar), Leipzig, 1782 […]. Scheller in 1782 used roman and italic for Latin words. The enviable author and typesetter had at his disposal four different fonts of the same size for four categories of words. […] And how much better-looking a combination is Alte Schwabacher and Breitkopf Fraktur than Garamond and semibold Garamond! Scheller in his grammar book perfectly presents the difference between German and Latin through the clever use of contrasting shapes, Fraktur and Schwabacher on the one hand, roman and italic on the other.

The roman used must be a “Garamond”, at least judging by the italics (although the italics seem to come from a different typeface, or are at least used in a slightly larger body, cf. p. 776–777), but this is not clear. In any case, what is certainly interesting, and Tschichold is right, is the use of the four typographic varieties, and above all the Alte Schwabacher–Breitkopf-Fraktur pair, which form an exemplary body of text.
