Grave illness was more than once his lot during his mission to England.[22] Shortly after his arrival in that country in 1757, he was seized with a violent attack of sickness, accompanied by delirium, which left him in an invalid condition for quite a time. From the account that he gives of the cupping, vomiting and purging that he underwent, under the care of good Doctor Fothergill, there would seem to have been no lack of opportunity for the escape of the disease, which, judging by the amount of bark that he took in substance and infusion, was probably some form of malarial fever. This attack gives a decidedly valetudinary tone to one of his subsequent letters to Deborah. "I am much more tender than I us'd to be," he said, "and sleep in a short Callico Bedgown with close Sleeves, and Flannel close-footed Trousers; for without them I get no warmth all Night. So it seems I grow older apace." Deborah's health, too, about this time was not overgood, for, a few months later, he writes to her: "It gives me Concern to receive such frequent Accts of your being indisposed; but we both of us grow in Years, and must expect our Constitutions, though tolerably good in themselves, will by degrees give way to the Infirmities of Age." Shortly after Franklin's arrival in England in 1764, he was seized with another attack of illness, but he was soon able to declare that, thanks to God, he was got perfectly well, his cough being quite gone, and his arms mending, so that he could dress and undress himself, if he chose to endure a little pain. A few months later, he says it rejoices him to learn that Deborah is freer than she used to be from the headache and the pain in her side. He himself, he said, was likewise in perfect health. Again he writes to Deborah in the succeeding year: "I congratulate you on the soon expected Repeal of the Stamp Act; and on the great Share of Health we both enjoy, tho' now going in Four-score (that is, in the fourth score)." He was not allowed, however, to indulge long the spirit of congratulation, for, a few months later, one of his letters to Deborah brings to our knowledge the fact that he had been very ill. After his recovery from this illness, he does not seem to have been attacked by anything again while in England, beyond a fit or so of the gout, and in 1768 he readily assents to the statement of Deborah that they were both blessed with a great share of health considering their years, then sixty-three. A few years more, however, and Franklin's correspondence indicates plainly enough that this statement was no longer applicable to Deborah. In the letter last-mentioned, her husband writes to her that he wonders to hear that his friends were backward in bringing her his letters when they arrived, and thinks it must be a mere imagination of hers, the effect of some melancholy humor she happened then to be in; and some four years afterwards he recommends to her a dietary for the preservation of her health and the
