This fact coincides in a most interesting manner with the biological fact that man is by nature a frugivorous animal. In the process of ripening, the starch of fruits undergoes a hydration similar to that which takes place in cooking and in pancreatic digestion, whereby the insoluble starch is converted into soluble starch, dextrine, and sugar. This explains, also, why well-ripened fruit may be eaten raw with impunity, while unripe fruit and farinaceous food of all sorts require cooking. In his diet, man, like his nearest relative, the monkey, being naturally a frugivorous animal, may eat fruits in the state in which Nature has provided them; but when he introduces other natural products into his bill of fare, he must adopt artificial means for securing the preparation for digestion which Nature makes in the ripening process of fruits. The coefficient of chlorine liberation (_m_) is very nearly uniform, indicating that the mastication of food and the cooking of food have little influence upon this digestive function. The coefficient of salivary activity (_c_) was determined independently for each test breakfast. Its practical uniformity indicates that there was no essential change in the character or quality of the saliva to account for the differences shown by the totals in relation to the stomach digestion of starch. DR. EDWARD HOOKER DEWEY AND THE “NO BREAKFAST PLAN” The “No Breakfast Plan,” evolved from the long experimental experience of Dr. Dewey, to secure much needed rest for the stomach and intestines, is described in a book bearing that title which can be had direct from the author by addressing him at his home, Meadville, Penn., U. S. A. “No Breakfast” is, evidently, a misnomer, but means, in the present application, an appetite _earned_ after arising from sleep. The writer, for instance, often begins work so early in the morning that by the time the ordinary breakfast is ready he has already done a fair day’s work. The writer has no reported details of the work of Dr. Dewey to add to this volume. In “Glutton or Epicure” full appreciation of this Esculapian Luther is expressed and extracts of his writings are reprinted. In fighting for more than forty years for the principle of less abuse of the tired body of man, Dr. Dewey has rendered a service that some time will be reckoned very great; and while there is no scientific report of the good doctor’s work to call for introductory comment, it would be equally unhealthy to miss an opportunity to express gratitude for what he has done for us all.
