With doctors of divinity the question is not so vexing or vexed; but it is said that of late a lion is rising in the way of rightly addressing doctors of medicine. If you wish to be attended by a physician who pays all visits after nightfall in evening dress, it is said that you are now to write Smythe Johnes, M.D., Esq., and not Dr. Smythe Johnes, as formerly. In England, the source of all our ceremonial woes, you cannot call a surgeon "doctor" without offence; he is Mr. Smythe Johnes when spoken to, but whether he is Mr. Smythe Johnes through the post, Heaven knows.
It is a thousand pities that when we cut ourselves off from that troubled source politically, we did not dam it up in all the things of etiquette. We indeed struck for freedom and sense at the very highest point, and began at once to write George Washington, President, as we still write William H. Taft, President. The Chief Magistrate is offered no taffy in our nation, or perhaps the word President is held to be taffy enough and to spare; for only the Governor of Massachusetts is legally even so much as Excellency. Yet by usage you are expected to address all ambassadors and ministers as Excellencies, and all persons in public office from members of Congress and of the Cabinet down to the lowest legislative or judicial functionaries as Honorables. This simplifies the task of directing envelopes to them, and, if a man once holds military rank in any peace establishment, he makes life a little easier for his correspondents by remaining General, or Captain, or Admiral, or Commander. You cannot Mister him, and you cannot Esquire him, and there is, therefore, no question as to what you shall superscribe him.
A score of years ago two friends, now, alas! both doctors of philosophy, of letters, and of laws, agreed to superscribe their letters simply Smythe Johnes and Johnes Smythe respectively, without any vain prefix or affix. They kept up this good custom till in process of time they went to Europe for prolonged sojourns, and there corrupted their manners, so that when they came home they began addressing each other as Esq., and have done so ever since. Neither is any the better for the honors they exchange on the envelopes they do not look at, and doubtless if mankind could be brought to the renunciation of the vain prefixes and affixes which these friends once disused the race would be none the worse for it, but all the better. One prints Mr. Smythe Johnes on one's visiting-card because it passes through the hands of a menial who is not to be supposed for a moment to announce plain Smythe Johnes; but it is the United States post-office which delivers the letters of Smythe Johnes, and they can suffer no contamination from a service which conveys the letters of plain William H. Taft to him with merely the explanatory affix of President, lest they should go to some other William H. Taft.
