There were few dentists, _eo nomine_, some sixty years ago. Our ancestors appear to have gotten along pretty comfortably, in spite of their teeth. Many of those, who practised the "_dental art_," had so little employment, that it became convenient to unite their dental practice, with some other occupation. Thus John Templeman, was a _broker and dentist_, at the northeast corner of the Old State House. Whitlock was, doubtless, frequently called out, from a rehearsal, at the play house, to pull a refractory grinder. Isaac Greenwood advertises, in the Columbian Sentinel of June 1, 1785, not only his desire to wait upon all, who may require his services, at their houses, in the dental line; but a variety of umbrellas, canes, silk caps for bathing, dice, chess men, and cane for hoops and bonnets, by the dozen, or single stick. In the Boston Mercury of Jan. 6, 1797, W. P. Greenwood combines, with his dental profession, the sale of piano-fortes and guitars. In 1799, the registered dentists were three only, Messrs. Isaac and Wm. P. Greenwood, and Josiah Flagg. In 1816, there were three only, Wm. P. Greenwood, Thomas Parsons, and Thomas Barnes. It would appear somewhat extravagant, perhaps, to state, that, including doctors of all sorts, there is a fraction more than two doctors to every one merchant, _eo nomine_, excluding commission merchants, of course, in the city of Boston. Such, nevertheless, appears to be the fact, unless Mr. Adams has made some important error, which I do not suspect, in his valuable Directory, for 1848-9. It will not be utterly worthless, to contemplate the quartermaster's department of this portentous army; and compare it with the corresponding establishment of other times. In 1789, there were fifteen druggists and apothecaries, in the town of Boston. Examples were exceedingly rare, in those days, of wholesale establishments, exclusively dealing in drugs and medicines. At present, we have, in this city, eighty-nine apothecaries, doing business, in as many different places--drugs and medicines are also sold, at wholesale, in forty-four establishments--there are fourteen special depots, for the sale of patent medicines, Gordak's drugs, Indian purgatives, Holman's restorative, Brandreth's pills, Sherry wine bitters, and pectoral balsam, Graefenberg's medicines, and many other kinds of nastiness--eighteen dealers exclusively in botanic medicines--ninety-seven nurses--twenty-eight undertakers--and eight warehouses for the sale of coffins!
