But the vexation of almost endless delay had its alleviations, apparently much more than enough to offset it. Early in September, 1757, that is to say some five or six weeks after his landing, Franklin was taken very ill of an intermittent fever, which lasted for eight weeks. During his convalescence he wrote to his wife that the agreeable conversation of men of learning, and the notice taken of him by persons of distinction, soothed him under this painful absence from family and friends; yet these solaces would not hold him there another week, were it not for duty to his country and the hope of being able to do it service. But after the early homesickness wore off, a great attachment for England took its place. He found himself a man of note among scientists there, who gave him a ready welcome and showed a courteous and flattering recognition of his high distinction in their pursuits. Thence it was easy to penetrate into the neighboring circle of literature, wherein he made warm personal friends, such as Lord Kames, David Hume, Dr. Robertson, and others. From time to time he was a guest at many a pleasant country seat, and at the universities. He found plenty of leisure, too, for travel, and explored the United Kingdom very thoroughly. When he went to Edinburgh he was presented with the freedom of the city; and the University of St. Andrews conferred on him the degree of Doctor of Laws; later, Oxford did the same. He even had time for a trip into the Low Countries. As months and finally years slipped away, with just enough of occupation of a dignified character to save him from an annoying sense of idleness, with abundant opportunities for social pleasure, and with a very gratifying deference shown towards himself, Franklin, who liked society and did not dislike flattery, began to think the mother country no such bad place. For an intellectual and social career London certainly had advantages over Philadelphia. Mr. Strahan, the well-known publisher of those days, whom Franklin used affectionately to call Straney, became his close friend, and was very insistent with him that he should leave the provinces and take up a permanent residence in England. He baited his hook with an offer of his son in marriage with Franklin's daughter Sarah. He had never seen Sarah, but he seems to have taken it for granted that any child of her father must be matrimonially satisfactory. Franklin wrote home to his wife that the young man was eligible, and that there were abundant funds in the Strahan treasury, but that he did not suppose that she would be able to overcome her terror of the ocean voyage. Indeed, this timidity on the part of his wife was more than once put forward by him as if it were really the feather which turned the scale in the choice of his future residence.
