The only sensible advice that can be given in this connection is that persons should take no more liquids that they feel a desire for, and they should avoid taking them in any quantity about meal time. What has just been said concerning water applies equally well to milk. When taken alone it very frequently agrees with patients much better than does solid food, but when mixed with the latter is prone to produce indigestion, just as does water. Fermented milk in the form of buttermilk is a very popular beverage in some parts of the world, but it may be well doubted as to whether it deserves the reputation for wholesomeness generally accorded it; being a liquid, and at the same time acid, it is peculiarly prone to increase acidity, and is not tolerated by persons who suffer with sour stomach. It should, however, be said that it, on the other hand, seems to agree particularly well with some people, and has been known when taken alone, at least temporarily, to relieve obstinate forms of indigestion. _Coffee._--The most universal beverage taken at meal time in America is undoubtedly coffee. Each morning countless thousands are cheered and stimulated by its invigorating properties to undertake their daily tasks, but, as is always the case after taking drugs that have such action the system has to pay the penalty in a reaction following later, during which the capacity for work is diminished. It is, however, true that the effect last referred to is not of such importance as to constitute in itself a serious objection to the use of coffee, but other ill results are rather prone to ensue that in many instances change the aspect of the question entirely. In a great many people, particularly after the first vigor of youth has passed, coffee produces anything but pleasant effects, and on some it seems to act as a downright poison. Like all liquids taken at meal time, it predisposes to acid indigestion, particularly when it is sweetened. It is likewise true that when it contains any considerable quantity of cream the liability to dyspeptic disturbances following its use are particularly great--doubtless as a result of the considerable quantity of melted fats that it contains under such circumstances.
