Liquid food or nourishment and no other is suitable for a sick person; an invalid can drink food when it would be impossible for him to swallow solid material. I have often seen the whim of patients who craved meat indulged; they got a juicy porterhouse steak with the understanding that it was to be thoroughly masticated before swallowing. As a rule, the patient is disappointed with his own bill of fare, and after trying one or two mouthfuls orders the meat taken away with the remark that it is as dry as a chip. But this same person will drink a milk punch, a thin gruel with the yellow or all of an egg beaten into it, with some degree of relish; salt should always be added and indeed, as much as the taste will permit, but sugar should be used as sparingly as possible. Salt is what is needed above all other seasoning; the system requires the chlorides for they are wasted in fevers, but even in health, the chlorides are very essential and salt is the best one we have; salt is the source of the hydrochloric acid in the stomach and one of the most important factors in albuminous digestion. The saliva is not secreted in sufficient quantity in fever to allow insalivation of food, or to moisten the solid morsel sufficiently to permit its being swallowed without a choking sensation as it glides into the stomach. A person prostrated by disease has not the strength to masticate solid food and that is another reason why liquid food is to be given. The famous physiologist, Dr. E. Brown-Séquard, is the author of a method for feeding the sick peculiarly his own, namely, that of administering small quantities of food at short intervals. He would give a glassful of milk punch in tablespoonful doses, repeating every ten or fifteen minutes; this method is advised for the treatment and cure of dyspepsia, anæmia, chlorosis, nervous diseases and even organic diseases of the stomach. No particular kind of food was selected for this treatment; butter, milk, cheese, and meats, bread and potatoes were alike to be given in small quantities and at short intervals. One or two mouthfuls even to be eaten at a time, and then repeated in ten or fifteen minutes, until thirty to forty ounces are consumed daily. This system never became a recognized expedient, it is wrong in theory, and certainly in practice; while it may be applicable in isolated cases, they would be so very few that this method of feeding forms the exception and not the rule.
