From the Cradle to the Grave we need DRINK, and we have not far to look for the reason, when we consider that at least seventy per cent. of the human body is composed of water, to compensate the perpetual waste of which, a fresh supply is, of course, absolutely necessary. This is taken with our food (all solid nutriment containing some water), and by the drink we consume. But, as the largest constituent part of the body is fluid, so, naturally, its waste is larger than that of the solid; this fluid waste being enormous. Besides the natural losses, every breath we exhale is heavily laden with moisture, as breathing on a cold polished surface, or a cold day by condensing the breath, will show; whilst the twenty-eight miles of tubing disposed over the surface of the human body will evaporate, _invisibly_, two or three pounds of water daily. Of course, in very hot weather, or after extreme exertion, this perspiration is much more, and is visible. To remedy this loss we must DRINK, as a stoppage of the supply would kill sooner than if solid food were withheld, for then the body would, for a time, live upon its own substance, as in the cases of the fasting men of the last two years; but few people can live longer than three days without drinking, and death by thirst is looked upon as one of the most cruel forms of dissolution. To palliate thirst, however, it is not absolutely necessary to drink, as a moist atmosphere or copious bathing will do much towards allaying it,—the one by introducing moisture into the system by means of the lungs, the other through the medium of the skin. Thirst is the notice given by Nature that liquid aliment is required to repair the waste of the body; and, as in the case of Hunger, she has kindly provided that supplying the deficiency shall be a pleasant sensation, and one calculated to call up a feeling of gratitude for the means of allaying the want. Indeed, no man knows the real pleasures of eating and drinking, until he has suffered both hunger and thirst.
