Cradock tells us that on one occasion, when Goldsmith was hard at work on his Natural History, he sent to Dr. Percy and himself, entreating them to finish some pages of his work which lay upon his table, and for which the press was urgent, he being detained by other engagements at Windsor. They met by appointment at his chambers in the Temple, where they found everything in disorder, and costly books lying scattered about on the tables and on the floor; many of the books on natural history which he had recently consulted lay open among uncorrected proof-sheets. The subject in hand, and from which he had suddenly broken off, related to birds. "Do you know anything about birds?" asked Dr. Percy, smiling. "Not an atom," replied Cradock; "do you?" "Not I! I scarcely know a goose from a swan: however, let us try what we can do." They set to work and completed their friendly task. Goldsmith, however, when he came to revise it, made such alterations that they could neither of them recognize their own share. The engagement at Windsor, which had thus caused Goldsmith to break off suddenly from his multifarious engagements, was a party of pleasure with some literary ladies. Another anecdote was current, illustrative of the carelessness with which he executed works requiring accuracy and research. On the 22d of June he had received payment in advance for a Grecian History in two volumes, though only one was finished. As he was pushing on doggedly at the second volume, Gibbon, the historian, called in. "You are the man of all others I wish to see," cried the poet, glad to be saved the trouble of reference to his books. "What was the name of that Indian king who gave Alexander the Great so much trouble?" "Montezuma," replied Gibbon, sportively. The heedless author was about committing the name to paper without reflection, when Gibbon pretended to recollect himself, and gave the true name, Porus. This story, very probably, was a sportive exaggeration; but it was a multiplicity of anecdotes like this and the preceding one, some true and some false, which had impaired the confidence of booksellers in Goldsmith, as a man to be relied on for a task requiring wide and accurate research, and close and long-continued application. The project of the Universal Dictionary, therefore, met with no encouragement, and fell through.
