10     A warning dream, a superstitious fancy, or a solemn prediction that death would occur at a certain day or at a certain hour, has not unfrequently produced all the signs of commencing and increasing disease, of approaching death and death itself at the hour announced, which could not happen without the simultaneous production of the inward change (corresponding to the state observed externally); and hence in such cases all the morbid signs indicative of approaching death have frequently been dissipated by an identical cause, by some cunning deception or persuasion to a belief in the contrary, and health suddenly restored, which could not have happened without the removal, by means of this moral remedy, of the internal and external morbid change that threatened death.
