_Rye-bread._--There is no reason why rye-bread should not be prepared in quite as wholesome a way as is wheaten-bread, and this grain should undoubtedly rank as one of the best of the cereals. Its use, however, is so limited in this country that it is scarcely necessary to go into a lengthy discussion as to its merits. It may be remarked that the ergot fungus frequently grows on this grain, and when ground up with it occasionally poisons the consumer where the quantity of the substance is large and the bread is eaten in considerable quantities. Instances of this kind are not uncommon among the peasantry of Europe, where a black bread made from rye is the staple article of diet. Of course, when making food-preparations of rye, we should be careful to have the flour thoroughly winnowed, and to cook the bread until sufficiently dry to acquire a proper consistency for chewing. _Corn-bread and Corn Food-products._--When made from perfectly sound grain, and if not allowed to undergo fermentative changes afterward, there can be no question that food-products of corn are entirely wholesome, and, from the standpoint of chemical composition, quite as nourishing as similar articles of diet prepared from other grains. It is, however, unfortunately true that we cannot, in the majority of instances, definitely assure ourselves that our corn-bread is made from grain that comes up to the above specification, nor can we be sure that the meal is fresh, or preserved at such a temperature as would forbid the growth of various germs. It has long been known that bad corn would kill horses, but notwithstanding this, we have accepted the view that no amount of deterioration in the grain could result harmfully to man. That this latter assumption is incorrect seems now in the highest degree probable. _Pellagra._--It is known that a very curious and fatal disease called pellagra is prevalent to a considerable degree at the present time in the United States, and it is not going too far to say that all of those best capable of judging are of the opinion that the malady is the result of eating just such corn as we know kills horses.
