The psychic factor in digestion is even more important than originally claimed by the author, and fully accounts for the strength attained by the Christian Science movement. In the "A.B.-Z. of Our Own Nutrition" are reprinted, for recent scientific reports, in addition to the papers of Dr. Van Someren and Professor Chittenden, before mentioned, articles and lectures by Dr. Professor Pawlow, the great Russian physiologist and one of the Board of Assessors in the International Nutrition Investigation, described in the "A.B.-Z.," (reprinted from the fine English Translation by Dr. W. H. Thompson, of Trinity College, Dublin; English publishers, Griffin & Co.; American publishers, Lippincott & Co.), on the mental influence over the salivary, gastric, and intestinal secretions. Also, nearly an hundred pages of most virile, readable, and important "Observations on Mastication," by Dr. Harry Campbell, M.D., F.R.C.P., of the North-west London Hospital; reprinted by courteous permission of the author and of the editor of the _Lancet_. Also, a description of the digestive process in animals as seen by aid of the Röntgen, or X-Ray; a most readable account of the infinite patience and application of Dr. W. B. Cannon, of the Harvard Medical School, devoted to learning the "reasons for things" done in the closed and secret laboratory of the stomach and intestines. The above is a necessary advertisement of another volume in the A.B.C. Life Series; because the details of this particular attempt to reduce the philosophy of every-day life to profitable simples is linked-up in several volumes developed in the course of study of the subject for location of the germinal causes. "Menticulture" was the first of the series and relates to the individual. "Happiness" came next and located the chief enemy of happiness in _Fearthought_, the unprofitable element of forethought. "That Last Waif" treated the question as related to the Social Whole, children in particular, and recommended _Social Quarantine_; by extension of infant education to the extreme of allowing no child to escape educational care. This present treatise deals with the first requirement of such infantile care and education, right feeding. DR. KELLOGG'S APPRECIATION The great Battle Creek Sanitarium, under the inspiration and direction of Dr. J. H. Kellogg, has grown to enormous proportions in thirty-seven years. It began with one patient in a two-storey frame house in a country village, and has been largely influential in creating the present proud distinction of Battle Creek, Michigan, with its millions upon millions of invested industrial capital.
