This book was not merely the result of his researches for the last fifteen years of his life, but of his general reading for nearly fifty years, when everything he read he remembered. Says Thackeray, "He reads twenty books to write a sentence; he travels one hundred miles to make a line of description." The extent and exactness of his knowledge were not only marvellous, but almost incredible. Mr. Buckle declared that Macaulay was perfectly accurate in all the facts which Buckle had himself investigated to write his "History of Civilization;" and so particular was he in the selection of words that he never allowed a sentence to pass muster until it was as good as he could make it. "He thought little of reconstructing a paragraph," says his biographer, "for the sake of one happy illustration." He submitted to the most tiresome mechanical drudgery in the correction of his proof-sheets. The clearness of his thought amid the profusion of his knowledge was represented in his writing by a remarkable conciseness of expression. His short, vigorous sentences are compact with details of fact, yet rich with color. His terseness has been compared to that of Tacitus. His power of condensation, aptness of phrase and epithet, and indomitable industry made him a master of rhetorical effect, in the use of his multifarious learning for the illustration of his themes. As soon as his last proof-sheet had been despatched to the printers, Macaulay at once fell to reading a series of historians from Herodotus downward, to measure his writings with theirs. Thucydides especially utterly destroyed all the conceit which naturally would arise from his unbounded popularity, as expressed in every social and literary circle, as well as in the Reviews. Like Michael Angelo, this Englishman was never satisfied with his own productions; and the only comfort he took in the impossibility of realizing his ideal was in the comparison he made of his own works with similar ones by contemporary authors. Then he was content; and then only appeared in his letters and diary that good-natured, self-satisfied feeling which arose from the consciousness that he was one of the most fortunate authors who had ever lived. There was nothing cynical in his sense of superiority, but an amiable self-assertion and self-confidence that only made men smile,--as when Lord Palmerston remarked that "he wished he was as certain of any one thing as Tom Macaulay was of everything." This self-confidence rarely provoked opposition, except when he was positive as to things outside his sphere. He wrote and talked sensibly and luminously on financial and social questions, on art, on poetry and the drama, on philosophy and theology; but on these subjects he was not an authority with specialists. In other words, he did not, so to speak, know everything profoundly, but only superficially; yet in history, especially English history, he was profound in analysis as well as brilliant in the
