That Dr. John cured at least one patient, we are told by Dr. Rush on the authority of Franklin, but it was Only himself of a tremor, and that by simply ceasing to take snuff. Dr. Pringle and himself, Franklin told Dr. Rush, observed that tremors of the hands were more frequent in France than elsewhere, and probably from the excessive use of snuff. "He concluded," says Dr. Rush, "that there was no great advantage in using tobacco in any way, for that he had kept company with persons who used it all his life, and no one had ever advised him to use it. The Doctor in the 81st year of his age declared he had never snuffed, chewed, or smoked."
Among the persons who sought Sir John's professional advice was Franklin himself. It was in relation to a cutaneous trouble which vexed him for some fourteen years, and broke out afresh when he was in his eighty-third year. But the best medicine that Franklin ever obtained from Sir John was his companionship upon two continental tours, one of which was inspired by the latter's desire to drink the waters at Pyrmont, and the other by the attractions of the French capital. When the news of Sir John's death reached Franklin at Passy he paid the usual heartfelt tribute. "We have lost our common Friend," he wrote to Jan Ingenhousz, "the excellent Pringle. How many pleasing hours you and I have pass'd together in his Company!"
Another English physician, for whom Franklin entertained a feeling of deep affection, was the Quaker Dr. John Fothergill. After the death of this friend, in a letter to Dr. John Coakley Lettsom, still another friend of his, and one of the famous English physicians of the eighteenth century, he expressed this extraordinary opinion of Dr. Fothergill's worth: "If we may estimate the goodness of a man by his disposition to do good, and his constant endeavours and success in doing it, I can hardly conceive that a better man has ever existed." No faint praise to be uttered by the founder of the Junto and one who valued above all things the character of a doer of good! Like Sir John Pringle, Dr. Fothergill belonged to the class of physicians who pursued medicine, as if it were a mistress not to be wooed except with the favor of the other members of the scientific sisterhood. He was an ardent botanist, and his collection of botanical specimens and paintings on vellum of rare plants was among the remarkable collections of his age. Two of his correspondents were the Pennsylvania botanists, John Bartram and Humphrey Marshall, who brought to his knowledge a flora in many shining instances unknown to the woods and fields of the Old World. His medical writings were held in high esteem, and were published after his death under the editorial supervision of Dr. Lettsom.
As a practitioner, he was eminently successful, and numbered among his patients many representatives of the most powerful and exclusive circles in London. What the extent of his practice was we can infer from a question put to him by Franklin in 1764.
By the way [he asked], when do you intend to live?—i. e., to enjoy life. When will you retire to your villa, give yourself repose, delight in viewing the operations of nature in the vegetable creation, assist her in her works, get your ingenious friends at times about you, make them happy with your conversation, and enjoy theirs: or, if alone, amuse yourself with your books and elegant collections?
To be hurried about perpetually from one sick chamber to another is not living. Do you please yourself with the fancy that you are doing good? You are mistaken. Half the lives you save are not worth saving, as being useless, and almost all the other half ought not to be saved, as being mischievous. Does your conscience never hint to you the impiety of being in constant warfare against the plans of Providence? Disease was intended as the punishment of intemperance, sloth, and other vices, and the example of that punishment was intended to promote and strengthen the opposite virtues.
All of which, of course, except the suggestion about retirement, which was quite in keeping with Franklin's conception of a rational life, was nothing more than humorous paradox on the part of a man who loved all his fellow-creatures too much to despair of any of them.
When Franklin himself was seized with a grave attack of illness shortly after his arrival in England on his first mission, Doctor Fothergill was his physician, and seems to have cupped and physicked him with drastic assiduity. The patient was not a very docile one, for he wrote to Deborah that, too soon thinking himself well, he ventured out twice, and both times got fresh cold, and fell down again; and that his "good doctor" grew very angry with him for acting contrary to his cautions and directions, and obliged him to promise more observance for the future. Always to Franklin the Doctor remained the "good Doctor Fothergill." Even in a codicil to his will, in bequeathing to one of his friends the silver cream pot given to him by the doctor, with the motto "Keep bright the chain," he refers to him by that designation.
Nor were his obligations as a patient the only obligations that Franklin owed to this friend. When his early letters on electricity were sent over to England, only to be laughed at in the first instance, they happened to pass under the eye of the Doctor. He saw their merit, advised their publication, and wrote the preface to the pamphlet in which they were published by Cave. But the things for which Franklin valued the Doctor most were his public spirit and philanthropy. He was well known in Philadelphia, and, when Franklin arrived in London in 1757, he was actively assisted by the Doctor in his effort to secure a settlement of the dispute over taxation between the Pennsylvania Assembly and the Proprietaries. Afterwards, when Franklin's second mission to England was coming to an end, the Doctor was drawn deeply into a vain attempt made by Lord Howe and his sister and David Barclay, another Quaker friend of Franklin, to compose the American controversy by an agreement with Franklin. For this business, among other reasons, because of "his daily Visits among the Great, in the Practice of his Profession," of which Franklin speaks in his history of these negotiations, he would have been a most helpful ally; if the quarrel had not become so embittered. But, as it was, the knot, which the negotiators were striving to disentangle, was too intricate for anything but the edge of the sword. When the negotiations came to nothing, the good Doctor, who knew the sentiments of "the Great" in London at that time, if any private person did, had no advice to give to Franklin except, when he returned to America, to get certain of the Doctor's friends in Philadelphia, and two or three other persons together, and to inform them that, whatever specious pretences were offered by the English ministry, they were all hollow, and that to obtain a larger field, on which to fatten a herd of worthless parasites, was all that was regarded. It was a bad day, indeed, for England when one of the best men in the land could hold such language.
The silk experiment in Pennsylvania furnished still another congenial field for the co-operation of Franklin and Doctor Fothergill; and, in a letter to Franklin, the latter also declared in startlingly modern terms that, in the warmth of his affection for mankind, he could wish to see "the institution of a College of Justice, where the claims of sovereigns should be weighed, an award given, and war only made on him who refused submission."
