"Friend to my life, which did not you prolong, The world had wanted many an idle song;" and of whom Swift said, that "he has more wit than we all have, and his humanity is equal to his wit." "If there were a dozen Arbuthnots in the world," said Swift, "I would burn 'Gulliver's Travels.'" Arbuthnot was of Swift's age, born in 1667, son of a Scotch Episcopal clergyman, who lost his living at the Revolution. His sons--all trained in High Church principles--left Scotland to seek their fortunes; John came to London and taught mathematics. He took his degree of Doctor of Medicine at St. Andrews in 1696; found use for mathematics in his studies of medicine; became a Fellow of the Royal Society; and being by chance at Epsom when Queen Anne's husband was taken ill, prescribed for him so successfully that he was made in 1705 Physician Extraordinary, and upon the occurrence of a vacancy in 1709 Physician in Ordinary, to the Queen. Swift calls him her favourite physician. In 1710 he was admitted Fellow of the Royal College of Physicians. That was Arbuthnot's position in 1712-13 when, at the age of forty-five, he wrote this "History of John Bull." He was personal friend of the Ministers whose policy he supported, and especially of Harley, Earl of Oxford, the Sir Roger of the History. After Queen Anne's death, and the coming of the Whigs to power, Arbuthnot lost his office at Court. But he was the friend and physician of all the wits; himself without literary ambition, allowing friends to make what alterations they pleased in pieces that he wrote, or his children to make kites of them. A couple of years before his death he suffered deeply from the loss of the elder of his two sons. He was himself afflicted then with stone, and retired to Hampstead to die. "A recovery," he wrote to Swift, "is in my case and in my age impossible; the kindest wish of my friends is euthanasia." He died in 1735. AUTHOR'S PREFACE. When I was first called to the office of historiographer to John Bull, he expressed himself to this purpose:--"Sir Humphrey Polesworth,* I know you are a plain dealer; it is for that reason I have chosen you for this important trust; speak the truth and spare not." That I might fulfil those his honourable intentions, I obtained leave to repair to, and attend him in his most secret retirements; and I put the journals of all transactions into a strong box, to be opened at a fitting occasion, after the manner of the historiographers of some eastern monarchs: this I thought was the safest way; though I declare I was never afraid to be chopped** by my master for telling of truth. It is from those journals that my memoirs are compiled: therefore let not posterity a thousand years hence look for truth in the voluminous annals of pedants, who are entirely ignorant of the secret springs of great actions; if they do, let me tell them they will be nebused.***
