Having, in obedience to your request, delivered my sentiments freely, you will perceive, that, besides the objections already mentioned to the person under whose care our friend is at present, I cannot approve of his being directed to take so many drugs, or of his being detained in town, at a season when he may enjoy, in the country, what is preferable to all medicine; I mean air, exercise, and, let me even add, diet. Had I known of our friend’s complaints earlier, I should have advised him to have met the advancing spring in the South of France; but at the season in which you will receive this letter, the moderate warmth, and refreshing verdure of England, are preferable to the sultry heats and scorched fields of the South. From the view I have of his complaints, I can have no hesitation in advising you to endeavour to prevail on him to quit his drugs, and to leave London without delay. Since he bears riding on horseback so well, let him enjoy that exercise in an atmosphere freed from the smoke of the town, and impregnated with the flavour of rising plants and green herbage; a flavour which may with more truth be called _pectoral_, than any of the heating resins, or loathsome oils, on which that term has been prostituted. Let him pass the summer in drinking the waters, and riding around the environs of Bristol. It will be easy for him to find a house in the free air of the country, at some distance from that town; and it will be of use to have an additional reason for rising early, and riding every morning. It is of the greatest importance that he continue that exercise every day that the weather will permit: a little cloudiness of the sky should not fright him from it; there is no danger of catching cold during the continuation of that movement which assists digestion, promotes the determination of blood from the lungs to the surface of the body, and is more salutary in the morning than after dinner. With respect to diet, he should carefully observe the important rule of taking food frequently, in small quantities, and never making a full meal; that the digestive organs may not be overpowered, or the vessels charged with too large a quantity of chyle at a time; which never fails to bring on oppressive breathing, and augments the fever and flushing, which in some degree succeeds every repast. Since all kinds of milk are found to disagree with his constitution, that nourishment, which is in general so well adapted to similar complaints, must be omitted, and light broths, with vegetable food, particularly of the farinaceous kind, substituted in its place.
