The stronger the nature of a patient, the safer it becomes to rely upon a single mode of procedure. Thus, cold packs may be sufficient in case of high fever if applied about every half hour or hour; or, if the temperature is not quite so high, at intervals, from one hour and a half to two hours With weaker persons more variety of procedure is imperative, but none of them must be too stringently applied. In these cases mild ablutions should be used several times during the day, and they may be alternated with packs of the whole lower part of the body or packs on the calves of the legs. Cool or cold enemas are rapidly absorbed and thus have a quieting influence on the large blood reservoir in the abdomen. Little mouthfuls of water are also taken from time to time, but too much water always weakens the patient. (C) DIET IN CASES OF FEVER. As diet in cases of fever I recommend the prescriptions of Professor Moritz, which coincide with my own experiences, so far as a fever diet is concerned; and in addition the physiologico-chemical cell-food which I have used for many years with the greatest success (Dech-Manna Diet). The importance of the latter is due to the fact that it not only _prevents_ the destruction of the cells, but has a general strengthening effect upon the system. Whatever the differences in manifestation the febrile diseases may show, the _febrile reduction of the digestive capacity of the stomach and the bowels is so characteristic_, that it should be specially noted in this connection. True, fever shows considerable _disturbance of metabolism_, since the _decomposition of the albumen is increased in an abnormal way_. This fact, however, does not demand any particular attention, in regard to diet. As far as possible during fever it is well to exercise an economizing influence on the decomposition of the albumen of the body through the introduction of _all kinds of food_ that produce energy, so that it is not necessary to _give preference to any one particular kind of food_. The injury to digestion during fever comprises not only the peptic functions, which manifest themselves clearly in a reduction of the excretion of hydrochloric acid, but all functions pertaining thereto, the motory as well as the resorptive.
