Excerpt from A System of Mature Medicine, Vol. 1: As Taught in McCormick Medical College; Optics and Ophthalmology In 1898 I published Optical Truths in which I gave clinical experiences with epilepsy, female ills, and all sorts of nervous diseases, explained how the nerve supply and demand could be measured, showed the fallacy of prisms as therapeutic agents, exploited the-straightening of cross-eyes with out operation and exposed ophthalmic Charlatans and their practices. For all of which I was roundly abused by some of the so-called authorities. In 1900 I began the publication of the Ophthalmologist, a monthly, which was continued for ten years, in which I had the means of answering critics and spreading good tidings as I discovered them. In 1905 I published Neurology and Metaphysics, a large, illustrated volume, in which were recorded in detail many discoveries beyond the field of Ophthalmology and the manner in which it was received was most gratifying. I still receive letters, almost weekly, from those who have tried out the propositions and found they all worked.
