I have emphasized the fact that the continued use of chloral is not so liable to end in the formation of a habit, as is the prolonged use of morphia or opium; not that physicians may exercise less care and discrimination in its employment, for the danger is sufficiently great, but simply to refute the statements of some men who are gone wild upon the subject of habituation and inebriety, and who suggest measures for reform, and plans for restraint and treatment, as impracticable and impossible as their statements are whimsical and truthless. Finally, be it distinctly understood, that many of the symptoms enumerated as occurring in both the morphine and chloral habituès, but especially the latter, are only found where the drug has been used in large amount, or for a long time. Every symptom will, moreover, be modified somewhat by the systemic peculiarities of each patient. The “mixed” habits, so called, where patients are using two or more narcotics at one time, have not been discussed separately, as they possess no distinctive characters, and the physician who understands the prominent points of each will have no trouble in detecting and treating these cases.
