nearly or quite fail to supply or replenish the waste of the delicate brain and nervous system; and should understand how the best foods for the active brain-worker can be procured. A dyspeptic myself, a member of a dyspeptic family, and observing much of that kind of misery and weakness which arises from digestive feebleness, I have been compelled to study the subject of food in its relation to bodily and mental and moral well-being, during many years; and it is not less a pleasure than a duty to say that an intimate acquaintance with the researches of the Health Food Co. and its products, has convinced me that this organization is the center and source of the best information obtainable in any land, on the subject of dietetics; that the food which it prepares from many substances, especially from the cereal grains, are the best in the world; and that all who seek to live wisely and well, all who are strong and would continue so, all who are feeble and would fain be strong, all in whom the spirit to lead noble and useful lives is willing, but in whom the flesh, alas! is weak—owe it to themselves and to all whom they have power to influence, to learn all that can be learned concerning the great work of this company. In this brief Appendix it is not possible to allude, even remotely, to all its investigations in the domain of dietetics, nor to fully indicate the valuable results which it has achieved. I shall be justified, however, in referring to a few of its more prominent applications of scientific thought to the daily needs of humanity.
