Should a Limenian in perfect health, who thus drinks water at stated periods, feel thirsty shortly after a meal concluded, as usual, with sugar or some sweet-meat and water, he is taught to endure the inconvenience rather than bring on himself indisposition by indulging his thirst. To understand this, it is requisite to know, that, until three hours have elapsed after the taking of the last meal, no one is supposed to drink even water, which is the most common beverage of the natives; for to commit such an irregularity would, it is believed, be to occasion a fit of indigestion or to hazard health. This may appear a ridiculous prejudice to those who are accustomed to quench their thirst, as often as it naturally arises, without regard to rules; but, on the coast of Peru, the neglect of this prophylactic rule of only drinking at stated periods, when it violates the established habits of an individual trained up in the observance of it, may be allowed to be injurious to the health, as it certainly disturbs the digestive functions. This strict attention to measured periods of drinking water is also countenanced in the hill-land of the interior, where digestion is usually so vigorous as not to require such nice precaution: but it is patronised by custom; and this, no doubt, the majority hold as a sufficient reason for the continuance of the practice. When a person suffers from acute febrile disease, and is only allowed very spare and tenuous diet, such as chicken soup, panada, tapioca, or arrow-root, &c.; then, from one meal to another, the regular interval is five hours; three hours after each meal, water, or some medicated drink, is given; and, two hours after this drink, the allotted aliment, of whatever simple sort it may be, is again repeated. Thus food and drink are regularly alternated till the patient is considered to be in a state which requires the supply of solid food; and then, as when in ordinary health, the interval from meal to meal is understood to be seven hours. The solid food given to the convalescent generally consists of chicken, which, of all the items in the list of Limenian dietary, is that in most general requisition. Now, for the proper digestion of the chicken, five hours are allowed before any medicated drink is ordered after it; and the principle recognised in this method is, that drink, which too much dilutes and weakens the gastric juice in the stomach, cannot with propriety be taken before chymification is complete.
