About his Time the _Roman_ Physicians sent their Consumptive Patients to _Alexandria_ in _Ægypt_, and with very good Success, as we find by both the _Pliny’s_; this was done partly for the Change of Air, but chiefly for the Sake of the Exercise by the Motion of the Ship, and therefore _Celsus_ says, _Si vera a Phthisis est, opus est longâ Navigatione_; and a little after he makes _Vehiculum & Navis_ to be two of the chiefest Remedies; and I am apt to believe they were the more inclin’d to make use of the Sea-Carriage, as an Exercise, for the sake of the Vomiting, which happens at the Beginning of it, that they might thereby supply their Want of gentle Emeticks, which at times are so beneficial in that Distemper, in which scarce any of the Emeticks which they then knew, can be us’d with Safety, and it was a great part of their Industry and Sagacity to make good what they wanted in Pharmacy by other Means. As for the other more common Exercises, that were daily practis’d, as it is very manifest from _Celsus_, _Cælius Aurelianus_, _Theodorus Priscianus_, and the rest of the _Latin_ Physicians. And we don’t want Instances of the Cures wrought by these means. _Suetonius_ tells us, that _Germanicus_ was Cur’d of a _Crurum Gracilitas_, as he expresses it, I suppose he means an _Atrophy_, by Riding; and _Plutarch_ in the Life of _Tully_ gives us an account of his Infirmness, and that he recovered a great Measure of Health by Travelling, and excessive Diligence in Rubbing and _Chafing_ his Body; and he himself in his _Brutus, seu de claris Oratioribus_, relates his Case, That he was so weak, that his Friends and Physicians advis’d him to leave off Pleading, which struck him so, that he thought he would undergo any Fatigue, rather than lose the Glory of his Profession, and so betook himself to Travelling, which with other regular Courses brought him to his Health again. _Pliny_, _lib. 31. Cap. 6._ tells us _Annæas Gallio_, who had been Consul, was Cured of a Consumption by a Sea Voyage; and _Galen_ gives us such Accounts of the good Effects of particular Exercises, and all People so unanimously apply’d themselves with Patience and Resolution to these Practices, that it cannot be suppos’d, but they must have been able to produce great and good Effects.
