Dr. W. A. Gray, who has already been mentioned as White’s associate in Denver, seems to have been doing business in Illinois some time in 1913 and a Princeton (Ill.) paper had some uncomplimentary things to say about him. Finally in July, 1913, this item appeared in a Princeton paper. “Dr. W. A. Gray, the goiter specialist who operated last winter at Princeton and Walnut until he became embroiled with Dr. Mark White, a Denver veterinary and originator of the cure, over a division of the spoils, has opened a goiter institute in Chicago under his own name. Advertisements of the Dr. Gray Goiter Institute appeared Sunday morning in the Chicago _Examiner_ and other morning papers. Dr. Gray and Mark White broke off their relations after their disagreement at Walnut, and Dr. Gray slightly changed the ingredients of the goiter cure and started off on his own hook.” One of Gray’s advertisements in Chicago newspapers made the claim that “Dr. Gray’s New Medical Treatment removes the cause of goiter in seven days.” [Illustration: Photographic reproduction (reduced) of the “professional” card used by “Dr. Mark White” after he came to Chicago.] The Tulsa (Okla.) associate of “Dr.” White seems to have been Dr. J. H. Morgan and the Tulsa papers of June, 1914, tell of “Dr.” White’s visit to that city “for the purpose of instructing Dr. J. H. Morgan in the technique of his new medical treatment for nervous disorders and goiter.” Some months later--in December, 1915--the following little item appeared in a Tulsa paper: “Dr. Mark White was found guilty in the county court yesterday of practicing medicine without a license and was fined $50. Doctor White is a goiter specialist.” In September, 1915, Mr. Thomas S. Hogan, the efficient counsel for the Illinois State Board of Health, instituted action against Mark White for practicing medicine without a license. The case was tried Oct. 15, 1915, and the jury, after being out four hours, returned a verdict of “not guilty.” Attorney Hogan attributes the failure to obtain a conviction to the testimony of Dr. Rachel Watkins, who said she had a partnership arrangement with White in carrying on the medical business. It was about this time that Mark White seems to have issued some new letterheads. These bore in their upper left hand corner the device “Rachel Watkins, M. D., Practice Limited to Goiter and Other Disorders of the Thyroid Glands,” while the upper right hand corner read “Mark White, Goiter Research.” On Dec. 9, 1915, Rachel Watkins, M. D., of Chicago, read a paper entitled “A Serum Treatment for Physiologically Defective Thyroids, With Clinical Reports” before the Stock Yards Branch of the Chicago Medical Society. The “serum treatment” discussed was Mark White’s “Goitreine” which, in the course of its checkered career, had lost its original name by the wayside. This paper appeared in the December, 1915, issue of the _Illinois Medical Journal_.
