BLACK, A—BLACK, J.

born in London on the 31st of January 1811. He was educated at Eton and Oriel college, Oxford, where he had a brilliant career, winning the Craven University scholarship, and taking a double first-class in classics and mathematics. He became a fellow of Oriel (1833), and won the Vinerian scholarship (1834), and fellowship (1840). He was called to the bar in 1837, but never practised. At school and at Oxford he was a contemporary of W. E. Gladstone, and at Oxford he began a lifelong friendship with J. H. Newman and R. W. Church; his classical and literary tastes, and his combination of liberalism in politics with High Church views in religion, together with his good social position and interesting character, made him an admired member of their circles. For two or three years (1841–1844) he wrote for The Times, and he helped to found The Guardian in 1846; he also did a good deal to assist the Tractarian movement. But he eventually settled down to the life of a government official. He began in 1844 as registrar of joint-stock companies, and in 1846 became commissioner of lands and emigration. Between 1857 and 1859 he was engaged in government missions abroad, connected with colonial questions, and in 1860 he was appointed permanent under-secretary of state for the colonies. Sir Frederic Rogers was the guiding spirit of the colonial office under six successive secretaries of state, and on his retirement in 1871 was raised to the peerage as Baron Blachford of Wisdome, a title taken from his place in Devonshire. He died on the 21st of November 1889.

A volume of his letters, edited by G. E. Marindin (1896), contains an interesting Life, partly autobiographical.


BLACK, ADAM (1784–1874), Scottish publisher, founder of the firm of A. & C. Black, the son of a builder, was born in Edinburgh on the 20th of February 1784. After serving his apprenticeship to the bookselling trade in Edinburgh and London, he began business for himself in Edinburgh in 1808. By 1826 he was recognized as one of the principal booksellers in the city; and a few years later he was joined in business by his nephew Charles. The two most important events connected with the history of the firm were the publication of the 7th, 8th and 9th editions of the Encyclopaedia Britannica, and the purchase of the stock and copyright of the Waverley Novels. The copyright of the Encyclopaedia passed into the hands of Adam Black and a few friends in 1827. In 1851 the firm bought the copyright of the Waverley Novels for £27,000; and in 1861 they became the proprietors of De Quincey’s works. Adam Black was twice lord provost of Edinburgh, and represented the city in parliament from 1856 to 1865. He retired from business in 1865, and died on the 24th of January 1874. He was succeeded by his sons, who removed their business in 1895 to London. There is a bronze statue of Adam Black in East Princes Street Gardens, Edinburgh.

BLACK, JEREMIAH SULLIVAN (1810–1883), American lawyer and statesman, was born in Stony Creek township, Somerset county, Pennsylvania, on the 10th of January 1810. He was largely self-educated, and before he was of age was admitted to the Pennsylvania bar. He gradually became one of the leading American lawyers, and in 1851–1857 was a member of the supreme court of Pennsylvania (chief-justice 1851–1854). In 1857 he entered President Buchanan’s cabinet as attorney-general of the United States. In this capacity he successfully contested the validity of the “California land claims”—claims to about 19,000 sq. m. of land, fraudulently alleged to have been granted to land-grabbers and others by the Mexican government prior to the close of the Mexican War. From the 17th of December 1860 to the 4th of March 1861 he was secretary of state. Perhaps the most influential of President Buchanan’s official advisers, he denied the constitutionality of secession, and urged that Fort Sumter be properly reinforced and defended. “For . . . the vigorous assertion at last in word and in deed that the United States is a nation,” says James Ford Rhodes, “for pointing out the way in which the authority of the Federal government might be exercised without infringing on the rights of the states, the gratitude of the American people is due to Jeremiah S. Black.” He became reporter to the Supreme Court of the United States in 1861, but after publishing the reports for the years 1861 and 1862 he resigned, and devoted himself almost exclusively to his private practice, appearing in such important cases before the Supreme Court as the one known as Ex-Parte Milligan, in which he ably defended the right of trial by jury, the McCardle case and the United States v. Blyew et al. After the Civil War he vigorously opposed the Congressional plan of reconstructing the late Confederate states, and himself drafted the message of President Johnson, vetoing the Reconstruction Act of the 2nd of March 1867. Black was also for a short time counsel for President Andrew Johnson, in his trial on the article of impeachment, before the United States Senate, and for William W. Belknap (1829–1890), secretary of war from 1869 to 1876, who in 1876 was impeached on a charge of corruption; and with others he represented Samuel J. Tilden during the contest for the presidency between Tilden and Hayes (see Electoral Commission). He died at Brockie, Pennsylvania, on the 19th of August 1883.

BLACK, JOSEPH (1728–1799), Scottish chemist and physicist, was born in 1728 at Bordeaux, where his father—a native of Belfast but of Scottish descent—was engaged in the wine trade. At the age of twelve he was sent to a grammar school in Belfast, whence he removed in 1746 to study medicine in Glasgow. There he had William Cullen for his instructor in chemistry, and the relation between the two soon became that of professor and assistant rather than of master and pupil. The action of lithontriptic medicines, especially lime-water, was one of the questions of the day, and through his investigations of this subject Black was led to the chemical discoveries associated with his name. The causticity of alkaline bodies was explained at that time as depending on the presence in them of the principle of fire, “phlogiston”; quicklime, for instance, was chalk which had taken up phlogiston, and when mild alkalis such as sodium or potassium carbonate were causticized by its aid, the phlogiston was supposed to pass from it to them. Black showed that on the contrary causticization meant the loss of something, as proved by loss of weight; and this something he found to be an “air,” which, because it was fixed in the substance before it was causticized, he spoke of as “fixed air.” Taking magnesia alba, which he distinguished from limestone with which it had previously been confused, he showed that on being heated it lost weight owing to the escape of this fixed air (named carbonic acid by Lavoisier in 1781), and that the weight was regained when the calcined product was made to reabsorb the fixed air with which it had parted. These investigations, by which Black not only gave a great impetus to the chemistry of gases by clearly indicating the existence of a gas distinct from common air, but also anticipated Lavoisier and modern chemistry by his appeal to the balance, were described in the thesis De humore acido a cibis orto, et magnesia alba, which he presented for his doctor’s degree in 1754; and a fuller account of them was read before the Medical Society of Edinburgh in June 1753, and published in the following year as Experiments upon magnesia, quicklime and some other alkaline substances.

It is curious that Black left to others the detailed study of this “fixed air” he had discovered. Probably the explanation is pressure of other work. In 1756 he succeeded Cullen as lecturer in chemistry at Glasgow, and was also appointed professor of anatomy, though that post he was glad to exchange for the chair of medicine. The preparation of lectures thus took up much of his time, and he was also gaining an extensive practice as a physician. Moreover, his attention was engaged on studies which ultimately led to his doctrine of latent heat. He noticed that when ice melts it takes up a quantity of heat without undergoing any change of temperature, and he argued that this heat, which as was usual in his time he looked upon as a subtle fluid, must have combined with the particles of ice and thus become latent in its substance. This hypothesis he verified quantitatively
