W. J. Cocker, Hand-book of punctuation (1878)
“ By gestures, tones of voice, oratorical pauses, emphasis, and in various ways, a speaker can make his meaning clear [iv] to his listeners; and so a writer should certainly use all the aids which punctuation, capitals, and italics afford, in presenting clearly what he has written for the perusal of others. Business men, however, seem to think that they are not amenable to the rules that govern good writers. They affirm that they have no time to punctuate their letters, and yet they subject others to the necessity of expending time and patience in trying to make out their meaning. ”
