A certain famous _French Physician_ being ill, fell into a violent _Delirium_, after some Days Illness of a continued Fever: the third Day of his _Delirium_, I know not by what Instinct, (says the Learned Father _Regnault_) made him desire a _Concert of Musick_; upon which, they play’d, and sung to him the Songs of _M. Bernier_[330]: Scarcely had he heard the first Notes, but his Eyes were calm; a Serenity was spread all over his Countenance, the Convulsions ceased, and he wept thro’ Excess of Pleasure; he was free from his Fever all the time of the Concert, but whenever they ceased singing, he relapsed into his former Condition: They fail’d not to continue so marvellous a Remedy, which always suspended his Indisposition. In short, after ten Days musical Entertainment, he was restored to his former Health. _Ibid._ Footnote 330: _Father Regn._ from _Hist. of the Royal Academy in France_. Another Instance, is a Dancing-Master of _Alais_ in _France_, who had the same Fate in the Year 1708; after a Fever of about four Days, and a long Lethargy, he fell into a _Delirium_, both mad and dumb. One of his Friends took his Violin, and plaid to him those Airs he was most accustom’d to: People thought at first, _that the Player was as mad as the Patient_; but, in a short time, the sick Man raised himself upright in his Bed, with the Air of a Man agreeably surpriz’d.... All his Motions discover’d the Pleasure he felt: Soon after he fell into a deep Sleep, and the Crisis he had during his Sleep, perfected his Cure. _Ibid._ One Reason of this strange Operation might be this, _viz._ The Sound of the Instrument agitates the Fibres, especially those that are in Unison, by that means brings to his Remembrance agreeable Perceptions ... sets the animal Spirits going, and restores them to their natural Course: These Spirits being moved, run into the Nerves and Muscles, where they have been used to run, in order to form the Motion of certain Airs; the Passages of the Blood thereby become more free: Hence that serene Air diffused all of a sudden over the Face of the sick Musician, who was cured by the Charms of his own Art. These two Instances are quoted by the Learned Dr. _Nieuwentyt_, who says, both of them (the Musician and Dancing-Master) were perfectly restored to their Senses by Musick. He also observes, that the Wound given by the _Tarantula_ can only be cured by the Sound of Musick, of which different Airs and Tunes must be play’d, according to the different Nature and Colour of those _Tarantula’s_ that have given the Wound[331]. Then adds; Footnote 331: _Religious Philosopher_, vol. I. Contempl. xiii. Sect. 270. That the famous _Italian_ Musician, _Angelo Vitali_ had related to him the following Story, and assured him of the Truth of it, _viz._
