This statement throws no light on the discrepancies in the statements with regard to the place of the iodinized oil in the treatment, namely: (_a_) the original statement that the oil was to be given a week after the serum; (_b_) White’s statement (quoted earlier in this report) that the oil “is only an adjunct or side treatment” and “is not always used or indicated”; (_c_) the statement in Dr. Watkins’ paper that the oil and the serum are given in combination. The Council declared the Mark White Goiter Serum and Mark White Iodinized Oil ineligible for New and Nonofficial Remedies and authorized publication of this report. Editorial Note on the Mark White “Serum” As some of our readers will remember, on April 26, 1913, The Journal called attention to the Mark White preparation which at that time was being exploited from Denver. The Propaganda Department has in its files a number of letters sent out from the Mark White concern at various times. One mailed in May, 1911, on the embossed stationery of “The Mark White Goiter Institute,” Exchange Building, Denver, was evidently a general letter sent to physicians, calling their attention to “the most important medical discovery of the age.” “Dr. Mark White, a graduate of the University of Pennsylvania,” said the letter, had discovered “a simple and harmless remedy” that would cure goiter. “Because of the desire to preserve the secrecy of this remedy it is given only at the office here.” It was then suggested that the doctor might send those of his patients who were suffering from thyroidism to the “Mark White Goitre Institute.” If he would do so he would be “given a commission of $10, in cases of the $50 fee with the additional $5 for each $50 increase.” It closed with some casuistic arguments, presumably for the purpose of overcoming the physician’s scruples, summing up the matter with the statement: “No right thinking man will allow a narrow and self-seeking system of ethics to stand between him and his duty to the sick and suffering.” About 1912 the name of the concern seems to have been changed, for we have in our files a letter addressed to a layman on the stationery of the “Mark White Goitre Treatment Company.” According to this letterhead the product this concern had for sale was “Goitreine” discovered by Mark White, “President and General Manager.” Mr. White’s letter to the sufferer from goiter assured him that if he would take “Goitreine” he might “be practically sure of an immediate and permanent cure.” “Goitreine,” according to White, “has absolutely and permanently cured 90 per cent.” of all cases of goiter in which it has been used--“and the other ten showed remarkable improvement.” It was efficacious for all forms of goiter and “cannot possibly harm.”
