I have good reason to believe, that an English sea-captain, who was on the verge of the grave with the consumption, in the spring of the year 1790, owed his perfect recovery to nothing but the above gradual manner, in which, by my advice, he made use of the exercises of riding in a carriage and on horseback. I have seen many other cases of the good effects of thus accommodating exercise to debility; and I am sorry to add, that I have seen many cases in which, from the neglect of this manner of using exercise, most of the species and degrees of it, have either been useless, or done harm. However carelessly this observation may be read by physicians, or attended to by patients, I conceive no direction to be more necessary in the cure of consumptions. I have been thus particular in detailing it, not only because I believe it to be important, but that I might atone to society for that portion of evil which I might have prevented by a more strict attention to it in the first years of my practice. The more the arms are used in exercise the better. One of the proprietary governors of Pennsylvania, who laboured for many years under consumptive diathesis, derived great benefit from frequently rowing himself in a small boat, a few miles up and down the river Schuylkill. Two young men, who were predisposed to a consumption, were perfectly cured by working steadily at a printing press in this city. A French physician in Martinique cured this disease, by simply rubbing the arms between the shoulders and the elbows, until they inflamed. The remedy is strongly recommended, by the recoveries from pulmonary consumption which have followed abscesses in the arm-pits. Perhaps the superior advantages of riding on horseback, in this disease, may arise in part from the constant and gentle use of the arms in the management of the bridle and the whip.
