When the man's lawyer heard of the effects upon the patient, he asked that the song might be sung while he was present, that he might then ask the patient about some very important papers of great value to the patient's family. As soon as the song was again sung by the quartet his intelligence returned. He informed the lawyer accurately as to the bank vault in which his box was locked, and told where he had left the keys in a private drawer of his desk. Although the effect of the music was not permanent as to his case, many persons who know of it feel that some time music may be so applied as permanently to cure even such cases, if kept up for a sufficient length of time. Accidents to the skull, heart diseases, nervous exhaustion, and spinal ailments seem especially amenable to music. Two of the hospital cases of paralysis were permanently relieved by music. In one of these cases instrumental music seemed to produce a strong electric effect. While four violins were accompanied by an organ, the patient could use his feet and hands, but it was several weeks before he could walk without music. In the other case, vocal music put an insomnia patient to sleep, but after sleeping through the program, the patient was better; after a few trials he returned home. Some of the hundred cases experimented upon were complete failures. But those conducting the experiments were convinced that the failure was attributable to the fact that they were unable to find the right kind of music. In the use of religious selections, "Pleyel's Hymn" made the patients of every ward worse; but "The Dead March" from Saul was soothing to typhoid patients. When this march was rendered softly, the nurses discovered that two cases had been so susceptible to the influences of the music that the physicians omitted the usual treatment and the patients recovered sooner than some other patients who had the disease in a less dangerous form. Children were helped by a different class of music from that used with adults, and difference in sex also was noted. Mothers who sing to their children may become the best investigators as to the power of vocal music on the healthy development of childhood.
