"The further investigation of your discovery by those competent will, I am confident, result in such a simplification of the rules for a healthy life that the medical profession, at present forced by a lack of knowledge of the vital processes of nutrition to base their treatment on the veriest empiricism, will then be able to teach all and sundry how to live. At present, all we can do is to treat and perchance cure for a time certain symptoms, allowing the patient to return afterwards to a mode of life that is really responsible for his malady. 'Disease is an abnormal mode of life.' (Harry Campbell.) The three factors in its causation are:
"(a) Cell structure.
"(b) Internal cell environment.
"(c) External body environment.
"Heredity determines, to a very large extent, our cell structure, and consequently our body structure.
"Sanitary science regulates our external body environment as much as the artificial and noxious habits of so-called civilisation will allow. The mental and physical external body environments have also their effect on the organism.
"Your discovery of simple rules for an Economic Nutrition will control the internal cell environment. In doing this, the predisposition to disease is materially affected. The internal cell environment being free from toxic material, and the cell itself better nourished, the cell's resistance to disease is increased, the possible source of disease being limited to the external body environment.
"In concluding this endorsement I can promise, to each and all who may intelligently practise the principles of Thorough Buccal-Digestion, a complete knowledge of their body's food requirements, or, as a patient of mine tersely put it, they will learn the way to 'run their own machines.'

Dr. Van Someren and the author, assisted by Dr. Professor Leonardi, of Venice, as Consulting Physiological-Chemist, and several colleagues, pursued some experiments during the winter of 1900-1901; and Dr. Van Someren read a paper on our work, entitled, "Was Luigi Cornaro Right?", before the meeting of the British Medical Association the following August.
The paper is too long to reprint here but it will be found in full in another volume, entitled, "The A.B.-Z. of Our Own Nutrition."
The following "Note" by Dr. Professor, Sir Michael Foster, K.C.B., M.P., F.R.S. etc., is a further link in the chain of development of appreciation of the need of serious attention to the science of human nutrition excited by this initiative.
