Two things are to be observed in the last remarks, which are, that children demand drink of any kind but seldom, and that even this occasional demand is often the special result of the use of animal food. Here comes out an important secret. It is the use of animal food, to a very great degree, in adults and children both, that creates so much of that unnatural thirst which prevails in the community. When we shall come to lay aside animal food, in childhood, youth, manhood and age, much that is now _called_ thirst will be banished; and much of the intemperance and other kinds of sensuality which follow in its train. It has been sometimes said that there is but one kind of drink in the world--and that is water. This is strictly, or rather _physiologically_ true. For, though many mixtures are _called_ drinks, it is only the water which they contain that answers any of the legitimate purposes for which drink was intended by the Creator. The object of drink, besides quenching our thirst, or rather _while_ it quenches it, is, not to be digested, like food, but to pass directly from the stomach into the blood-vessels, and dilute and temper the blood, rendering it more fit to answer the great purpose of sustaining life and health. Now, there is nothing that can do this but water. Alcohol cannot do it, nor can turpentine, oil, quicksilver, melted lead, or any other liquid. Tea, coffee, chocolate, small beer, soda water, lemonade, &c., which are nearly all water, quench the thirst very well, it is true; but not quite so well as water alone would. The narcotic principle of the first two, the alcoholic principle of the fourth, and the mucilage, nutriment, acid, and alkali of the rest, are in the way; for thirst would be quenched still better without them, even when it is of an unnatural kind. Indeed, the same or similar remarks may be made in regard to all other mixtures which are usually proposed as drinks. Even milk and water, molasses and water, &c., in favor of which so much is said, are objectionable, as mere drinks. Not that they contain anything poisonous, but they evidently contain nutriment; and even this, except as a part or the whole of a regular meal, does harm; for it sets the stomach at work when it needs repose. Mere drink, as I have already said, is never digested. But if the drinks above mentioned, and even milk and water, are objectionable, what shall we say of cider, wine, and ardent spirits?--substances which contain, the latter one half, and the two former from one twentieth to one fourth alcohol. Surely, nobody will deny that these substances ought, at all events, to be banished from the nursery. And yet we occasionally find them there, not only for the use of the mother, to the ruin of the child, indirectly--but also, in some of their smoother forms, for the use of the child itself.
