the Physician thought fit, which gave it a greater Energy; and after its Operation had recourse to another milder Method, to take off the Heat or Disorder which might have been caus’d by the Medicine. In these Practices they were so dexterous and successful, that tho’ their Ætiology strictly taken, was wrong, yet if a Man diligently attends to their Reasoning from Effects, he may be satisfi’d, that they were able by these Methods to do some wonderful Cures; and indeed they sometimes had such surprizing Success, that the abovemention’d _Herodicus_, an Eminent Master of Exercises, thought he could Cure all Distempers by those Means, and went Empirically to work upon the Bodies of those who put themselves under his Care, and was so extravagant, as to attempt to Cure Fevers by such Methods, for which he is ridicul’d by _Hippocrates_, in the _Sixth Book_ of his _Epidemicks_, and the _Third Section_. As for _Galen_, he follows _Hippocrates_ in this, as close as in other things, and declares his Opinion of the Benefit of Exercises in several places; his _Second_ Book, _de Sanitate Tuendâ_, is wholly upon the Use of the _Strigil_, or the Advantage of Regular _Chafing_; he has wrote a little Tract, _de Parvâ Pilâ_, wherein he recommends an Exercise, by which the Body and Mind are both at the same time affected. In his Discourse to _Thrasibulus_, which is a Dispute, whether the Preservation of the Health properly belongs to the Art of Physick, or to the Gymnastick Art, he inveighs against the _Athletick_, and other violent Practices of the _Gymnasium_, but approves of the more moderate Exercises, as subservient to the Ends of a Physician, and consequently part of that Art.
