The MSS. of Tasso, still preserved, are illegible from the vast number of their corrections. I have given a fac-simile, as correct as it is possible to conceive, of one page of Pope's MS. Homer, as a specimen of his continual corrections and critical erasures. The celebrated Madame Dacier never could satisfy herself in translating Homer: continually retouching the version, even in its happiest passages. There were several parts which she translated in six or seven manners; and she frequently noted in the margin--_I have not yet done it_. When Pascal became warm in his celebrated controversy, he applied himself with incredible labour to the composition of his "Provincial Letters." He was frequently twenty days occupied on a single letter. He recommenced some above seven and eight times, and by this means obtained that perfection which has made his work, as Voltaire says, "one of the best books ever published in France." The Quintus Curtius of Vaugelas occupied him thirty years: generally every period was translated in the margin five or six different ways. Chapelain and Conrart, who took the pains to review this work critically, were many times perplexed in their choice of passages; they generally liked best that which had been first composed. Hume had never done with corrections; every edition varies from the preceding ones. But there are more fortunate and fluid minds than these. Voltaire tells us of Fenelon's Telemachus, that the amiable author composed it in his retirement, in the short period of three months. Fenelon had, before this, formed his style, and his mind overflowed with all the spirit of the ancients. He opened a copious fountain, and there were not ten erasures in the original MS. The same facility accompanied Gibbon after the experience of his first volume; and the same copious readiness attended Adam Smith, who dictated to his amanuensis, while he walked about his study. The ancients were as pertinacious in their corrections. Isocrates, it is said, was employed for ten years on one of his works, and to appear natural studied with the most refined art. After a labour of eleven years, Virgil pronounced his Æneid imperfect. Dio Cassius devoted twelve years to the composition of his history, and Diodorus Siculus, thirty. There is a middle between velocity and torpidity; the Italians say, it is not necessary to be a stag, but we ought not to be a tortoise. Many ingenious expedients are not to be contemned in literary labours. The critical advice, To choose an _author_ as we would a _friend_,
