A serious illness now follows,--a weakness of the heart, from the effects of which Macaulay died a few years afterwards. He retires to Clifton, and gives himself up to getting well, visiting Barley Wood, and driving in his private carriage among the most interesting scenery in the west of England. But he was never perfectly well again, although he continued to work on his History. His intimate friends saw the change in him with sadness, but he himself was serene and uncomplaining. Although he suffered from an oppression of the chest, he still on great occasions addressed the House. His mind was clear, but his voice was faint. The last speech he made was in behalf of the independence of the Scottish Church. The strain of the House of Commons proved to be too great for his now enfeebled constitution. "Nor could he conceal from himself and his friends," says Trevelyan, "that it was a grievous waste, while the reign of Anne still remained unwritten, for him to consume his scanty stock of vigor in the tedious and exhaustive routine of political existence; waiting whole evenings for the vote, and then ... trudging home at three in the morning through the slush of a February thaw." He therefore spared himself as a member of Parliament, and carefully husbanded his powers in order to work upon his book. He gave himself more time for his annual vacation, yet would write when he could on the subjects which engrossed his life. His labors were too severe for his strength, but he worked on, and even harder and harder. At length on the 25th of November, 1855, Macaulay sent to the printer the last twenty pages of his History, and an edition of twenty-five thousand was ordered. Within a generation one hundred and forty thousand copies of the work were sold in the United Kingdom alone. Six rival translators were engaged in turning it into German; and it was published in the Polish, the Danish, the Swedish, the Italian, the French, the Dutch, the Spanish, the Hungarian, the Russian, and the Bohemian languages, to say nothing of its immense circulation in the United States. Such extraordinary literary popularity was accompanied by great honors. In 1857 Macaulay was created a British Peer and elected Lord High Steward of the borough of Cambridge. The academies of Utrecht, Munich, and Turin elected him to honorary membership. The King of Prussia made him a member of the Order of Merit. Oxford conferred on him the degree of Doctor of Civil Law, and he was elected president of the Philosophical Institution of Edinburgh. He could have little more in the way of academic and governmental honors.
