- If the physician clearly perceives what is to be cured in diseases, that is to say, in every individual case of disease (knowledge of disease, indication), if he clearly perceives what is curative in medicines, that is to say, in each individual medicine (knowledge of medical powers), and if he knows how to adapt, according to clearly defined principles, what is curative in medicines to what he has discovered to be undoubtedly morbid in the patient, so that the recovery must ensue - to adapt it, as well in respect to the suitability of the medicine most appropriate according to its mode of action to the case before him (choice of the remedy, the medicine indicated), as also in respect to the exact mode of preparation and quantity of it required (proper dose), and the proper period for repeating the dose; - if, finally, he knows the obstacles to recovery in each case and is aware how to remove them, so that the restoration may be permanent, then he understands how to treat judiciously and rationally, and he is a true practitioner of the healing art .
- The lukewarm baths at 25 to 27° serve to arouse the slumbering sensibility of fibre in the apparent dead (frozen, drowned, suffocated) which benumbed the sensation of the nerves. Though only palliative, still they often prove themselves sufficiently active, especially when given in conjunction with coffee and rubbing with the hands. They may give homœopathic aid in cases where the irritability is very unevenly distributed and accumulated too unevenly in some organs as is the case in certain hysteric spasms and infantile convulsions. In the same way, cold baths 10 to 6° in persons cured medically of chronic diseases and with deficiency of vital heat, act as an homœopathic aid. By instantaneous and later with repeated immersions they act as a palliative restorative of the tone of the exhausted fibre. For this purpose, such baths are to be used for more than momentary duration, rather for minutes and of gradually lowered temperature, they are a palliative, which, since it acts only physically has no connection with the disadvantage of a reverse action to be feared afterwards, as takes place with dynamic medicinal palliatives.
