started with his staff for Panjkora. On the 27th General Jeffreys resumed punitive operations in the Mamund valley, destroying numerous villages. On the 30th he encountered strong opposition at Agrah, and had 61 casualties. On the 2nd of October General Blood arrived at Inayat Killa with reinforcements, and on the 11th the Mamunds tendered their submission. The total British loss in the Mamund valley was 282 out of a force which never exceeded 1200 men. After marching into Buner, and revisiting the scenes of the Umbeyla expedition of 1863, the Malakand field-force was broken up on the 21st of January. The objects of the expedition were completely attained, in spite of the great natural difficulties of the country. The employment of imperial service troops with the Peshawar column marked a new departure in frontier campaigns. (C. J. B.)
MOHONK LAKE, a summer settlement at the northern end of
Lake Mohonk, Ulster county, New York, U.S.A., about 14 m.
N.W. of Poughkeepsie. It is served from New Paltz, about 1 m.
S.E. (about 512 m. by stage), by the Wallkill Valley railway, a
branch of the West Shore. The lake is a small body of water,
picturesquely situated 1245 ft. above the sea-level, on Sky Top
Mountain (1542 ft.), one of the highest peaks of the Shawangunk
range. The highest point of Sky Top lies just east of the south
end of the lake; close by, to the west, Eagle Cliff rises to a height
of 1412 ft. The development of this beautiful region into a
summer resort and the holding of Indian and arbitration conferences
here have been due to Albert Keith Smiley (b. 1828),
a graduate of Haverford College (1849), who conducted an
English and classical academy in Philadelphia in 1853–1857,
was principal of the Oak Grove academy at Vassalboro, Maine,
in 1858–1860, was principal and superintendent of the Friends
school at Providence, Rhode Island, in 1860–1879, and became a
member of the United States Board of Indian Commissioners in
1879. In 1869 he bought, at the northern end of Lake Mohonk,
a tract of land on which he built a large hotel. Here, in October
1883, the first Conference of the Friends of the American Indian
met; these conferences have since been held annually, their
scope being enlarged in 1904 to include consideration of the
condition of “other dependent peoples”—i.e. the natives of the
Philippines, Porto Rico and Hawaii. The first conference on
international arbitration was held here in June 1895.
MOHR, KARL FRIEDRICH (1806–1879), German pharmacist, son of a well-to-do druggist in Coblentz, was born on the 4th of November 1806. Being a delicate child he received much of his early education at home, in great part in his father’s laboratory. To this may be traced much of the skill he showed in devising instruments and methods of analysis. At the age of twenty-one he began to study chemistry under Leopold Gmelin, and, after five years spent in Heidelberg, Berlin and Bonn, returned with the degree of Ph.D. to join his father’s establishment. On the death of his father in 1840 he succeeded to the business, retiring from it for scientific leisure in 1857. Serious pecuniary losses led him at the age of fifty-seven to become a privatdozent in Bonn, where in 1867 he was appointed, by the direct influence of the emperor, extraordinary professor of pharmacy. He died at Bonn on the 28th of September 1879. Mohr was the leading scientific pharmacist of his time in Germany, and he was the author of many improvements in analytical processes. His methods of volumetric analysis were expounded in his Lehrbuch der chemisch-analytischen Titrirmethode (1855), which won the special commendation of Liebig and has run through many editions. His Geschichte der Erde, eine Geologie auf neuer Grundlage (1866), also obtained a wide circulation. In a paper “Über die Natur der Wärme,” published in the Zeitschrift für Physik in 1837, he gave one of the earliest general statements of the doctrine of the conservation of energy in the words: “besides the 54 known chemical elements there is in the physical world one agent only, and this is called Kraft (energy). It may appear, according to circumstances, as motion, chemical affinity, cohesion, electricity, light and magnetism; and from any one of these forms it can be transformed into any of the others.”
MOHS, FRIEDRICH (1773–1839), German mineralogist, was born at Gernrode in the Harz Mountains, on the 29th of January 1773. He was educated at Halle, and at the mining academy at Freiburg. He spent much time in Austria in studying mineralogy and mining, and became professor of mineralogy at Gratz in 1812. On the death of Werner in 1817, he was appointed to the chair of mineralogy in the mining academy of Freiburg, and in 1826 he became professor of mineralogy and superintendent of the Imperial Cabinet at Vienna. His great work was the Grundriss der Mineralogie (Eng. trans. Treatise on Mineralogy, by Wilhelm Haidinger, 1825). He died at Agardo, near Belluno, Italy, on the 29th of September, 1839.
MOHUN, CHARLES MOHUN, 4th Baron (c. 1675–1712), was the son of the 3rd Baron Mohun, who died in October 1677 as the result of a wound received while acting as second in a duel. The boy had no regular guardian, and before he was seventeen he had earned an unpleasant notoriety in London for rowdyism and brawling, had fought a duel and had been tried on a charge of murder. His friend, Captain Richard Hill, a roystering young officer, was in love with the actress Mrs Bracegirdle, and thought William Mountfort, the actor, to be his successful rival. On the night of the 9th of December 1692 Mohun assisted Hill to attempt the actress’s abduction. The attempt failed, and Mohun and Hill then escorted Mrs Bracegirdle to her house, and subsequently remained together outside drinking till the appearance of Mountfort, who lived close at hand. Greetings were exchanged between Mohun and Mountfort, and the latter made a disparaging remark about Hill, who either without warning (according to Mountfort’s deathbed statement) or in fair fight (according to other evidence) ran Mountfort through the body, and then absconded. Mohun was arrested and put on trial in Westminster Hall before his peers for murder as an accessory before the fact (1693), but by an overwhelming majority the peers found him not guilty. This verdict has been severely criticized, notably by Macaulay, who saw in it merely a gross instance of class favouritism. But a careful examination of the evidence (in the State Trials) justifies the decision, and establishes the presumption that the fight was a fair one. In 1699 Mohun was put on his trial for another alleged murder, but was unanimously and quite justly acquitted. His boon companion, Edward Rich, earl of Warwick (1673–1701), who was tried on a separate indictment for the same crime, was found guilty of manslaughter. On this occasion Mohun expressed regret for his past life, and he seems subsequently to have made a genuine attempt to alter his ways and to have taken a practical interest in public affairs. But in 1712 his violent temper again got the better of him, and he forced the 4th duke of Hamilton, with whom he had been at law for some years, into a desperate duel in Hyde Park in the early hours of the 15th of November, in which both combatants were killed. Thackeray has utilized this incident in Esmond. Lord Mohun had no issue, and on his death the barony, which was created in 1628 in favour of his great-grandfather John Mohun (c. 1592–1640), became extinct.

MOHUN, MICHAEL (c. 1625–1684), English actor, played at the Cockpit in Drury Lane before the Civil War. He served on the king’s side with credit and was promoted captain, and subsequently, in Flanders, major. At the Restoration he returned with Charles II. and took up his former profession, playing a great variety of parts, usually as second to Charles Hart.
MOHUR, the name of a Persian gold coin, used in India from the 16th century. The word is taken from the Persian muhr a seal or ring. Between 1835 and 1891 a gold coin, also called a “mohur,” was struck by the government of British India and was of the nominal value of 15 rupees. On the establishment of a gold standard in India in 1899, on the basis of 16d. a rupee,
