Taken in moderate quantities, cold water quenches thirst, allays inordinate heat of the body, promotes the process of digestion, and, by being absorbed into the system, repairs the loss of the fluid portion of the blood, occasioned by the cutaneous and other exhalents. If taken in too large quantities, or immediately before a meal, it dilutes the gastric juice to such an extent as to incapacitate it for performing, in the normal manner, the digestive process; but if taken during a meal, and in moderate quantities, it acts partially as a solvent for the food, and thus proves highly advantageous. The large quantities of cold water advised by the hydropathists cannot but prove eventually the source of dyspeptic and other complaints, for the reason that, like most other substances, when taken in excess, it tends to weaken the tone and impair the functions of the digestive organs.
