In the present lectures I have endeavored to carry the thought still further and to develop the fundamental principles on which treatment and prophylaxis are to be based. I have also been much more explicit in regard to diet, and have given the exact dietary which has been used with advantage in very many cases in private and hospital practise. In regard to medical treatment I have also been more definite, although it would be quite impossible to indicate all the different remedies which those and other patients have taken over varying periods of time, to meet different requirements of the system and individual peculiarities. I think and believe, however, that sufficient data are given to enable the competent and careful physician, who is able and willing to give sufficient time and adequate attention to these cases, to accomplish the same results, provided he has thoroughly mastered and applied the matter contained in these two small books. I fully realize the responsibility I have undertaken in gathering and revealing the evidence of the unsatisfactory results of the manner of regarding and treating cancer in years past, and certainly would not have done this were I not so strongly assured that there was something better to offer. How far I am right in my thesis I now leave to the kindly judgment of my professional brethren. My only hope is that I may, in some measure, have assisted in stemming the tide of the fearful ravages made by cancer, and that others may investigate still more deeply along the lines of its medical aspects, with increasingly satisfactory results.
