I really believe, from the results of my experiences for the past fifteen years in getting tips from Mother Nature, and trying to induce mankind in general and my friends in particular to accept them as "straight" from Mother Nature, that persons who have enough respect for themselves to be interested in physical culture must come to the rescue of the pseudo-scientists who are dulled by their own dope, and who are suffering from the malaria which collects in the dark ruts they are following in the tortuous complications of the alimentary canal. The physical culturists must build models of normality for the scientists to study. When giving information as to what happens in the mouth, and as to what happens as a result of proper head digestion, I feel as if I am sitting on the upper lip of Mother Nature herself, and entrusting her messages to the current of her own sweet breath for distribution among her human children. CHAPTER VI WHAT IS HEAD DIGESTION? My Study of the Subject--The Mouth as a Digestive Organ--Dr. Cannon's Researches--Pawlow's Proofs In the latest comprehensive treatise on human nutrition, under the title of "Food and the Principles of Dietetics," by Dr. Robert Hutchinson, of London, more than six hundred pages are devoted to the subject. Of these, just fifty lines are given to "Mouth Digestion." In a footnote of sixty-four words Dr. Hutchinson has stated the case of the importance of careful eating, with admission of a fact that would mean emancipation from most of the human disabilities if it were repeated in nurseries and primary schools as religiously as are the ordinary rules of "polite conduct," and held by Society to be the basis of respectability, which it really is. When I first took up the study of dietetics in academic circles, nearly fifteen years ago, physiologists did not concede that there was any mouth digestion at all. Putting food in the mouth was for the purpose of mixing it with saliva so that it could be formed into a "bolus" for convenient swallowing. Now it is recognised that there is some mouth digestion. In the meantime Pawlow[J] has demonstrated that the psychic influence has much to do with digestion. Cannon, also, has shown by the evidence of the Röntgen rays that mental states retard and even stop entirely the digestive processes that are going on in the stomach, and has asserted, as has also Pawlow, that the stomach digestive juices flow in response to the reports and stimulation of taste, pouring out into the cavity of the stomach juices appropriate for the digestion of the particular food being tasted, in advance of its arrival in the stomach.
