At any rate Dr. Wilkinson receives the information he asks for, and beyond returning a brief note of thanks to the local doctor and saying that he will give the matter thorough attention as soon as he gets a little respite from his rush of duties, that is the end of it for the time being. But Dr. Wilkinson is not idle. He is conducting, or rather his secretary is, a similar correspondence with scores of other physicians and prospective patients. From the letters thus received a card system is arranged, all the “prospects” being grouped by localities. One day Dr. Wilkinson finds that he has some fifty good “prospects” in the immediate vicinity of some good town, and decides to make a round up. He then writes, either to the prospective patients in that neighborhood, or the physicians, if his correspondence with the latter has been encouraging, a letter somewhat as follows: G. H. WILKINSON, M.D. SPECIALIST IN CHRONIC DISEASES —— Michigan Avenue Thomas H. Jennings, M.D., Godfrey’s Corners, Ia. Dear Doctor Jennings: Since the receipt of your letter relative to the case of Mr. Smith I have been called to —— for consultation 81in a serious case. I will be at the —— hotel on Thursday next but will be very busy, and do not think it safe to make any engagements, aside from the consultation, for that day. If you can arrange to meet me on Friday (the following day) between 10 and 11 a.m., I will remain over. I suggest this as it will afford us an opportunity of discussing Mr. Smith’s case to better advantage than it is possible to do by mail. There will, of course, be no fee attached to this service on my part. Kindly let me know at once whether I may expect to have the pleasure of meeting you so that I may arrange my time accordingly. Yours fraternally, ———— Dr. Jennings is impressed by the compliment thus paid him by the eminent specialist. So are the dozen or more other physicians to whom Dr. Wilkinson writes, most of them hastening to make engagements to meet the specialist at varying hours. If the correspondence has been entirely with the prospective patient, and no family physician has been enlisted as an intermediary, the “come on” letter is made to read differently. In cases of this kind the doctor would say: G. H. WILKINSON, M.D. SPECIALIST IN CHRONIC DISEASES —— Michigan Avenue Mr. Thomas Ratcliffe, Eagle Mills, Ia. Dear Sir: Since writing you last I have been called to —— for consultation in a serious case and will be at the —— hotel on Thursday next. As I can arrange to have a little leisure I would suggest that you meet me there at 11 a.m. so that I may be able to make a satisfactory diagnosis of your case, and thus be in position to advise you intelligently as to the prospects for obtaining relief.
