To distinguish between the course of rhetorical ideas, and the growth of style on the one hand, and of systematic rhetoric on the other, is perhaps to endeavor after too nice a distinction. Yet when we read sixteenth-century English, we may see, between the general effort to use prose with effect and the rather arid sequence of treatises on formal rhetoric, certain definite ideas on prose expression, certain views as to the best vocabulary, certain views on sentence-structure or figures of speech. The frank, vigorous prose of Latimer has style of a sort, the slight treatise of Cox has system. Neither the one thing nor the other is the opinion pro and con as to inkhorn words, for example. The following paper notes in the direction of the vocabulary only, a conscious effort to determine some fundamental principles which should obtain in the use of English as a means of literary expression.
