_These things are not owing to Notion and Speculation, but to Practical Observation; I cannot tell otherwise how to explain what I have seen to be the Effects of such means; I have seen a Poor Gentleman at ~Hampstead~, in the most deplorable extremity of a Consumption, betake himself to Riding twice or thrice a day, upon his Waters, put a stop for a time to his Distemper, and keep Death as it were at a Bay for some Weeks; which plainly shew’d, that if he had done so sooner, his former Medicines would undoubtedly have took effect; and how shall I account for this, but after some such manner as I have here insisted on? This is the Sum of my Thoughts on this Case, and if it does not strike the Imaginations of some People with so much Surprize, as other Pharmaceutick Discourses, I cannot help it; nay, if any should be so hard upon me, as to alledge that I am quite mistaken in the Cure of this Disease, when far advanc’d, let it be so; yet I hope they will allow me thus much, that it appears plain enough, for the Nature and Power of Exercise, that we ought to distinguish in this Distemper in like manner, as we do in another, which it would not be good Manners to mention, at the same time with the Consumption of the Lungs; in which latter Case, if a Young ~Debauchee~ happens to get a Misfortune, he does not let it run on till it come under another Denomination, but looks out for a present Cure, which may then be certainly obtain’d; and so I think it is no less obvious, if Exercises be as efficacious as I assert, that it is our Choice, whether a Cough shall run on to a Consumption; that is, I understand, that when a Cough comes to last above a Month, and begins to chop in its Indications, to require one while incrassating Medicines, another while attenuating ones; I say it is high time to look out, and set upon a resolute Course of Riding; that by a Series of Journeys, continued Day after Day without intermission, the obstructed Perspirations may be restor’d, which may then be easily effected, because the Body not being then much impair’d, so many Millions of Succussions coming close upon one another, must affect both the Strainers of the whole Body, and the Juices to be strain’d; and he who can oppose a Truth so manifest, must fly in the Face of Nature, and deny the Principles of the Oeconomy._
