If examination were made of the excreta through the pores of an individual during 24 hours, some conclusion might be definitely arrived at as to any germs of disease present in the body and in course of expulsion in this way. All bacteria incident to detrimental processes proceeding within the human organism, are to be found in the perspiration. Freckles indicate a certain predisposition inherent in the blood, while some forms of eczema point to the conclusion that there are diseased processes in action within the body. It is most important under this system to determine the chemical condition of the body in each individual case. Acids or alkalines prevail. If the former, patients have bad teeth, a disposition to gout, diabetes and cancer. The normal condition is the predominance of alkalines. In such cases as the former, physiological chemistry will point to the counterbalancing of the acids to establish a correct composition of the blood, and thus to prevent the impending danger. The biological system of health which is rapidly taking the place of all others, is equipped with so searching a knowledge of the human organism that no disease, be it ever so adroitly concealed, can escape its minute attention; not excepting even the disposition to disease. The old adage is still true that "prevention is better than cure" and the intelligent person will probably recognize the wisdom of so safe and sane a course and endeavor to prevent the evils to which he may be exposed. Thus, for his own satisfaction, if he be wise he will adopt these two simple precautions: (1) Examination by an accredited hygienic-dietetic physician. (2) Regulation of his mode of living in accordance with the course prescribed. The words of the famous Moleschott ring true today, more than in the past, when he said: "One of the principal questions a patient should ask his physician is, how to make good, healthy blood." Experience shows that there is but one method to attain good blood,--that _priceless factor_ upon which our _thinking_, our _feeling_, our _power_ and our _progeny depend_, and that is by means of _correct food and nutrition_.
