It will have been seen that I am careful in the selection of cases for this treatment. Conducted under the best circumstances for success, it involves a good deal that is costly. Neither does it answer as well, and for obvious reasons, in hospital wards; and this is most true in regard to persons who are demonstratively hysterical. As a rule, the worse the case, the more emaciated, the more easy is it to manage, to control, and to cure. It is, as Playfair remarks, the half-ill who constitute the difficult cases. I am also very careful as to being sure of the absence of certain forms of organic disease before flattering myself with the probability of success. But not all organic troubles forbid the use of this treatment. Advanced Bright's disease does, though the early stages of contracted kidney are decidedly benefited by it, if proper diet be prescribed; but intestinal troubles which are not tubercular or malignant do not; nor do moderate signs of chronic pulmonary deposits, or bronchitis.[13] Some special consideration needs to be given to the subject of heart-disease. Especially in cases of broken compensation, by lessening the work required of the heart so that it needs to beat both less often and with less force, the simple maintenance of the recumbent position is a great aid to recovery, and massage properly used will still further relieve the heart. Disturbed compensation is usually accompanied by failure of nutrition, often by distinct anæmia, and these and the anxiety which naturally enough affects the mind of a person with cardiac disorder are all best handled, at first at least, by quiet and rest. Later, the methods of Schott, baths and resistance movements, may carry the improvement further. Even in old and established cases of valvular disease much may be done if the patient have confidence and the physician courage enough to insist upon a sufficient length of rest. The palpitation and dyspnoea of exophthalmic goitre are promptly helped by rest and massage, and with other suitable measures added, cures may be effected even in this intractable ailment. In former editions I have advised against any attempt to treat the true melancholias, which are not mere depression of spirits from loss of all hope of relief, by this method, but wider experience has convinced me that rest and seclusion may often be successfully prescribed to a certain extent and in certain cases.
