Mr. Harte's conjecture concerning your distemper seems to be a very reasonable one; it agrees entirely with mine, which is the universal rule by which every man judges of another man's opinion. But, whatever may have been the cause of your rheumatic disorder, the effects are still to be attended to; and as there must be a remaining acrimony in your blood, you ought to have regard to that, in your common diet as well as in your medicines; both which should be of a sweetening alkaline nature, and promotive of perspiration. Rheumatic complaints are very apt to return, and those returns would be very vexatious and detrimental to you; at your age, and in your course of travels. Your time is, now particularly, inestimable; and every hour of it, at present, worth more than a year will be to you twenty years hence. You are now laying the foundation of your future character and fortune; and one single stone wanting in that foundation is of more consequence than fifty in the superstructure; which can always be mended and embellished if the foundation is solid. To carry on the metaphor of building: I would wish you to be a Corinthian edifice upon a Tuscan foundation; the latter having the utmost strength and solidity to support, and the former all possible ornaments to decorate. The Tuscan column is coarse, clumsy, and unpleasant; nobody looks at it twice; the Corinthian fluted column is beautiful and attractive; but without a solid foundation, can hardly be seen twice, because it must soon tumble down. Yours affectionately. LETTER LXXVII LONDON, August 7, O. S. 1749. DEAR BOY: By Mr. Harte's letter to me of the 18th July N. S., which I received by the last post, I am at length informed of the particulars both of your past distemper, and of your future motions. As to the former, I am now convinced, and so is Dr. Shaw, that your lungs were only symptomatically affected; and that the rheumatic tendency is what you are chiefly now to guard against, but (for greater security) with due attention still to your lungs, as if they had been, and still were, a little affected. In either case, a cooling, pectoral regimen is equally good. By cooling, I mean cooling in its consequences, not cold to the palate; for nothing is more dangerous than very cold liquors, at the very time that one longs for them the most; which is, when one is very hot. Fruit, when full ripe, is very wholesome; but then it must be within certain bounds as to quantity; for I have known many of my countrymen die of bloody-fluxes, by indulging in too great a quantity of fruit, in those countries where, from the goodness and ripeness of it, they thought it could do them no harm. 'Ne quid nimis', is a most excellent rule in everything; but commonly the least observed, by people of your age, in anything.
