jurisprudence and logic, in addition to editing his father’s professional papers. Bentham’s first publication was his Catalogue des plantes indigènes des Pyrénées et du Bas Languedoc (Paris, 1826), the result of a careful exploration of the Pyrenees in company with G. A. Walker Arnott (1799–1868), afterwards professor of botany in the university of Glasgow. It is interesting to notice that in it Bentham adopted the principle from which he never deviated, of citing nothing at second-hand. This was followed by articles on various legal subjects: on codification, in which he disagreed with his uncle, on the laws affecting larceny and on the law of real property. But the most remarkable production of this period was the Outline of a New System of Logic, with a Critical Examination of Dr Whately’s Elements of Logic (1827). In this the principle of the quantification of the predicate was first explicitly stated. This Stanley Jevons declared to be “undoubtedly the most fruitful discovery made in abstract logical science since the time of Aristotle.” Before sixty copies had been sold the publisher became bankrupt and the stock went for wastepaper. The book passed into oblivion, and it was not till 1873 that Bentham’s claims to priority were finally vindicated against those of Sir William Hamilton by Herbert Spencer. In 1836 he published his Labiatarum genera et species. In preparing this work he visited, between 1830–1834, every European herbarium, several more than once. The following winter was passed in Vienna, where he produced his Commentationes de Leguminosarum generibus, published in the annals of the Vienna Museum. In 1842 he removed to Pontrilas in Herefordshire. His chief occupation for some succeeding years was his contributions to the Prodromus Systematis Naturalis Regni Vegetabilis, which was being carried on by his friend, A. P. deCandolle. In all these dealt with some 4730 species.
In 1854 he found the maintenance of a herbarium and library too great a tax on his means. He therefore offered them to the government on the understanding that they should form the foundation of such necessary aids to research in the Royal Botanic Gardens at Kew. At the same time he contemplated the abandonment of botanical work. Fortunately, he yielded to the persuasion of Sir William Hooker, John Lindley and other scientific friends. In 1855 he took up his residence in London, and worked at Kew for five days a week, with a brief summer holiday, from this time onwards till the end of his life. As his friend Asa Gray wrote: “With such methodical habits, with freedom from professional or administrative functions, which consume the time of most botanists, with steady devotion to his chosen work, and with nearly all authentic material and needful appliances at hand or within reach, it is not so surprising that he should have undertaken and have so well accomplished such a vast amount of work, and he has the crowning merit and happy fortune of having completed all that he undertook.” The government, in 1857, sanctioned a scheme for the preparation of a series of Floras or descriptions in the English language of the indigenous plants of British colonies and possessions. Bentham began with the Flora Hongkongensis in 1861, which was the first comprehensive work on any part of the little-known flora of China. This was followed by the Flora Australiensis, in seven volumes (1863–1878), the first flora of any large continental area that had ever been finished. His greatest work was the Genera Plantarum, begun in 1862, and concluded in 1883 in collaboration with Sir Joseph Hooker, “the greater portion being,” as Sir Joseph Hooker tells us, “the product of Bentham’s indefatigable industry.” As age gradually impaired his bodily powers, he seemed at last only to live for the completion of this monumental work.
When the last revise of the last sheet was returned to the printer, the stimulus was withdrawn, and his powers seemed suddenly to fail him. He began a brief autobiography, but the pen with which he had written his two greatest works broke in his hand in the middle of a page. He accepted the omen, laid aside the unfinished manuscript and patiently awaited the not distant end. He died on the both of September 1884, within a fortnight of his 84th birthday.
The scientific world received the Genera Plantarum with as unanimous an assent as was accorded to the Species Plantarum of Linnaeus. Bentham possessed, as Professor Daniel Oliver remarked, “an insight of so special a character as to deserve the name of genius, into the relative value of characters for practical systematic work, and as a consequence of this, a sure sifting of essentials from non-essentials in each respective grade.” His preparation for his crowning work had been practically lifelong. There are few parts of the world upon the botany of which he did not touch. In the sequence and arrangement of the great families of flowering plants, different views from those of Bentham may be adopted. But Bentham paved the way by an intimate and exact statement of the structural facts and their accurate relationship, which is not likely to be improved. In method and style, in descriptive work, Bentham was a supreme master. This, to quote Professor Oliver again, is “manifest not only in its terseness, aptness and precision, but especially in the judicious selection of diagnostic marks, and in the instinctive estimate of probable range in variation, which long experience and innate genius for such work could alone inspire.” (W. T. T.-D.)
BENTHAM, JEREMY (1748–1832), English philosopher and jurist, was born on the 15th of February 1748 in Red Lion Street, Houndsditch, London, in which neighbourhood his grandfather and father successively carried on business as attorneys. His father, who was a wealthy man and possessed at any rate a smattering of Greek, Latin and French, was thought to have demeaned himself by marrying the daughter of an Andover tradesman, who afterwards retired to a country house near Reading, where young Jeremy spent many happy days. The boy’s talents justified the ambitious hopes which his parents entertained of his future. When three years old he read eagerly such works as Rapin’s History and began the study of Latin. A year or two later he learnt to play the violin and to speak French. At Westminster school he obtained a reputation for Greek and Latin verse writing; and he was only thirteen when he was matriculated at Queen’s College, Oxford, where his most important acquisition seems to have been a thorough acquaintance with Sanderson’s logic. He became a B.A. in 1763, and in the same year entered at Lincoln’s Inn, and took his seat as a student in the queen’s bench, where he listened with rapture to the judgments of Lord Mansfield. He managed also to hear Blackstone’s lectures at Oxford, but says that he immediately detected the fallacies which underlay the rounded periods of the future judge.
Bentham’s family connexions would naturally have given him a fair start at the bar, but this was not the career for which he was preparing himself. He spent his time in making chemical experiments and in speculating upon legal abuses, rather than in reading Coke upon Littleton and the Reports. On being called to the bar he “found a cause or two at nurse for him, which he did his best to put to death,” to the bitter disappointment of his father, who had confidently looked forward to seeing him upon the woolsack. The first fruits of Bentham’s studies, the Fragment on Government, appeared in 1776. This masterly attack upon Blackstone’s praises of the English constitution was variously attributed to Lord Mansfield, Lord Camden and Lord Ashburton. One important result of its publication was that, in 1781, Lord Shelburne (afterwards first marquess of Lansdowne) called upon its author in his chambers at Lincoln’s Inn. Henceforth Bentham was a frequent guest at Bowood, where he saw the best society and where he met Miss Caroline Fox (daughter of the second Lord Holland), to whom he afterwards made a proposal of marriage. In 1785 Bentham started, by way of Italy and Constantinople, on a visit to his brother, Samuel Bentham, a naval engineer, holding the rank of colonel in the Russian service; and it was in Russia that he wrote his Defence of Usury. Disappointed after his return to England in 1788 in the hope which he had entertained, through a misapprehension of something said by Lord Lansdowne, of taking a personal part in the legislation of his country, he settled down to the yet higher task of discovering and teaching the principles upon which all sound legislation must proceed. The great work, upon which he had
