In lecturing the teacher of literature must give attention to minor points as well: he will ask his class after analysing a verse to give him the parts of speech and the peculiar features of the feet which it contains: these latter should be so familiar in poetry as to make their presence desired even in the prose of oratory. He will point out what words are barbarous, what improperly used, and what are contrary to the laws of language.
