which he created ultimately dwindled away under the hands of his degenerate descendants, leaving not a wrack behind, we have in the presence of the Turks in Europe a consequence of his rule, since it was the advance of his armies which drove their Osmanli ancestors from their original home in northern Asia, and thus led to their invasion of Bithynia under Othman, and finally their advance into Europe under Amurath I.

JENKIN, HENRY CHARLES FLEEMING (1833–1885), British
engineer, was born near Dungeness on the 25th of March 1833,
his father (d. 1885) being a naval commander, and his mother
(d. 1885) a novelist of some literary repute, her best books perhaps
being Cousin Stella (1859) and Who breaks, pays (1861). Fleeming
Jenkin was educated at first in Scotland, but in 1846 the
family went to live abroad, owing to financial straits, and he
studied at Genoa University, where he took a first-class degree
in physical science. In 1851 he began his engineering career as
apprentice in an establishment at Manchester, and subsequently
he entered Newall’s submarine cable works at Birkenhead. In
1859 he began, in concert with Sir William Thomson (afterwards
Lord Kelvin), to work on problems respecting the making and
use of cables, and the importance of his researches on the resistance
of gutta-percha was at once recognized. From this time
he was in constant request in connexion with submarine telegraphy,
and he became known also as an inventor. In partnership
with Thomson, he made a large income as a consulting
telegraph engineer. In 1865 he was elected F.R.S., and was
appointed professor of engineering at University College, London.
In 1868 he obtained the same professorship at Edinburgh University,
and in 1873 he published a textbook of Magnetism and
Electricity, full of original work. He was author of the article
“Bridges” in the ninth edition of this encyclopaedia. His
influence among the Edinburgh students was pronounced, and
R. L. Stevenson’s well-known Memoir is a sympathetic tribute
to his ability and character. The meteoric charm of his conversation
is well described in Stevenson’s essay on “Talk and
Talkers,” under the name of Cockshot. Jenkin’s interests were
by no means confined to engineering, but extended to the arts and
literature; his miscellaneous papers, showing his critical and
unconventional views, were issued posthumously in two volumes
(1887). In 1882 Jenkin invented an automatic method of
electric transport for goods—“telpherage”—but the completion
of its details was prevented by his death on the 12th of June
1885. A telpher line on his system was subsequently erected
at Glynde in Sussex. He was also well known as a sanitary
reformer, and during the last ten years of his life he did much
useful work in inculcating more enlightened ideas on the subject
both in Edinburgh and other places.
JENKINS, SIR LEOLINE (1623–1685), English lawyer and diplomatist, was the son of a Welsh country gentleman. He was born in 1623 and was educated at Jesus College, Oxford, of which he was elected a fellow at the Restoration in 1660, having been an ardent royalist during the civil war and commonwealth; and in 1661 he became head of the college. In the same year he was made registrar of the consistory court of Westminster; in 1664 deputy judge of the court of arches; about a year later judge of the admiralty court; in 1689 judge of the prerogative court of Canterbury. In these offices Jenkins did enduring work in elucidating and establishing legal principles, especially in relation to international law and admiralty jurisdiction. He was selected to draw up the claim of Charles II. to succeed to the property of his mother, Henrietta Maria, on her death in August 1666, and while in Paris for this purpose he succeeded in defeating the rival claim of the duchess of Orleans, being rewarded by a knighthood on his return. In 1673, on being elected member for Hythe, Jenkins resigned the headship of Jesus College. He was one of the English representatives at the congress of Cologne in 1673, and at the more important congress of Nijmwegen in 1676–1679. He was made a privy councillor in February 1680 and became secretary of state in April of the same year, in which office he was the official leader of the opposition to the Exclusion Bill, though he was by no means a pliant tool in the hands of the court. He resigned office in 1684, and died on the 1st of September 1685. He left most of his property to Jesus College, Oxford, including his books, which he bequeathed to the college library, built by himself; and he left some important manuscripts to All Souls College, where they are preserved. Jenkins left his impress on the law of England in the Statute of Frauds, and the Statute of Distributions, of which he was the principal author, and of which the former profoundly affected the mercantile law of the country, while the latter regulated the inheritance of the personal property of intestates. He was never married.

Bliss (4 vols., London, 1813–1820), and History and Antiquities of the University of Oxford, edited by J. Gutch (Oxford, 1792–1796).
JENKINS, ROBERT (fl. 1731–1745), English master mariner, is known as the protagonist of the “Jenkins’s ear” incident, which, magnified in England by the press and the opposition, became a contributory cause of the war between England and Spain (1739). Bringing home the brig “Rebecca” from the West Indies in 1731, Jenkins was boarded by a Spanish guarda-costa, whose commander rifled the holds and cut off one of his ears. On arriving in England Jenkins stated his grievance to the king, and a report was furnished by the commander-in-chief in the West Indies confirming his account. At first the case created no great stir, but in 1738 he repeated his story with dramatic detail before a committee of the House of Commons, producing what purported to be the ear that had been cut off. Afterwards it was suggested that he might have lost the ear in the pillory.
Jenkins was subsequently given the command of a ship in the East India Company’s service, and later became supervisor of the company’s affairs at St Helena. In 1741 he was sent from England to that island to investigate charges of corruption brought against the acting governor, and from May 1741 until March 1742 he administered the affairs of the island. Thereafter he resumed his naval career, and is stated in an action with a pirate vessel to have preserved his own vessel and three others under his care (see T. H. Brooke, History of the Island of St Helena (London, 2nd ed., 1824), and H. R. Janisch, Extracts from the St Helena Records, 1885).
JENKS, JEREMIAH WHIPPLE (1856– ), American economist, was born in St Clair, Michigan, on the 2nd of September 1856. He graduated at the university of Michigan in 1878; taught Greek, Latin and German in Mt. Morris College, Illinois; studied in Germany, receiving the degree of Ph.D. from the university of Halle in 1885; taught political science and English literature at Knox College, Galesburg, Ill., in 1886–1889; was professor of political economy and social science at Indiana State University in 1889–1891; and was successively professor of political, municipal and social institutions (1891–1892), professor of political economy and civil and social institutions (1892–1901), and after 1901 professor of political economy and politics at Cornell University. In 1899–1901 he served as an expert agent of the United States industrial commission on investigation of trusts and industrial combinations in the United States and Europe, and contributed to vols. i., viii. and xiii. of this commission’s report (1900 and 1901), vol. viii. being a report, written wholly by him, on industrial combinations in Europe. In 1901–1902 he was special commissioner of the United States war department on colonial administration, and wrote a Report on Certain Economic Questions in the English and Dutch Colonies in the Orient, published (1902) by the bureau of insular affairs; and in 1903 he was adviser to the Mexican ministry of finance on projected currency changes. In 1903–1904 he was a member of the United States commission on international exchange, in especial charge of the reform of currency in China; in 1905 he was special representative of the United States with the imperial Chinese special mission visiting the United States. In 1907 he became a member of the United States immigration commission. Best known as an expert on “trusts,” he has written besides on elections, ballot reform, proportional representation, on education (especially as a training for citizenship), on legislation regarding highways, &c.
