Women more frequently than men are the victims of unscrupulous doctors. People do not often question the skill or the opinion of the fashionable physician; they take for granted the truth of all he may say, forgetting for the time that he has a pecuniary interest in the work that may possibly result in the death of the patient. UNNECESSARY OPERATIONS. How many people die from wholly unnecessary operations? Only the hospital records and the immediate friends of the patient can tell. These words are written to put people on their guard. Dishonest doctors are everywhere, especially in big cities. Chicago is full of them. They may be strictly ethical and affect to despise the advertiser. They do so, however, only from a business standpoint. They hate opposition, and somehow the advertising doctor manages to get a goodly share of the business, and is oftentimes the superior in skill in his particular line or specialty to his ethical brother. There are good doctors and bad ones, just as there are good and bad men in every walk and business of life. In my experience as a detective I have met with both kinds. In these pages I will deal with the advertising doctor only. I will do, and have done, what I can to drive the dishonest ones out of the business. The eye doctor, professing to cure blindness or other diseases of the eye without the knife, is one of the most dangerous and dishonest men in the medical profession. Chicago has its full quota of this form of quackery. There are two men in this city--Dr. M---- and Dr. O----, who are national advertisers. Both have been exposed in a recent New York weekly paper at the instigation of the American Medical Association. It is noteworthy, however, that this same paper accepted a full-page advertisement from Dr. O---- only a few months before the expose, thus deluding thousands of its readers. The price paid for one page and one issue was fifteen hundred dollars. This sum, paid to but one paper, will give the reader some idea of the vast expense to which the quack is put to place his name before the public in his effort to rob the blind. This same Dr. O---- pays out annually sixty thousand dollars for advertising alone. He employs twenty typewriters--mostly girls. The correspondence is handled entirely by the clerks, the doctor rarely ever seeing a letter. He employs but one assistant, a young man fresh from college. No personal interviews with patients are asked for or desired. It is a mail order business almost exclusively. Occasionally a patient comes to the city to see this great oculist. Dr. O---- himself is hardly ever in evidence. He spends most of his time in summer resorts and European capitals. The only medicine used is a solution of boric acid in water. The same can be bought at any drug store for a few cents. His charges are ten dollars per month.
