The bay was discovered by the Portuguese navigator Antonio de Campo, one of Vasco da Gama’s companions, in 1502, and the Portuguese post of Lourenço Marques was established not long after on the north side of the English river. In 1720 the Dutch East India Company built a fort and “factory” on the spot where Lourenço Marques now stands; but in 1730 the settlement was abandoned. Thereafter the Portuguese had—intermittently—trading stations in the Espirito Santo. These stations were protected by small forts, usually incapable, however, of withstanding attacks by the natives. In 1823 Captain (afterwards Vice-Admiral) W. F. W. Owen, of the British navy, finding that the Portuguese exercised no jurisdiction south of the settlement of Lourenço Marques, concluded treaties of cession with native chiefs, hoisted the British flag, and appropriated the country from the English river southwards; but when he visited the bay again in 1824 he found that the Portuguese, disregarding the British treaties, had concluded others with the natives, and had endeavoured (unsuccessfully) to take military possession of the country. Captain Owen rehoisted the British flag, but the sovereignty of either power was left undecided till the claims of the Transvaal Republic rendered a solution of the question urgent. In the meantime Great Britain had taken no steps to exercise authority on the spot, while the ravages of Zulu hordes confined Portuguese authority to the limits of their fort. In 1835 Boers, under a leader named Orich, had attempted to form a settlement on the bay, which is the natural outlet for the Transvaal; and in 1868 the Transvaal president, Marthinus Pretorius, claimed the country on each side of the Maputa down to the sea. In the following year, however, the Transvaal acknowledged Portugal’s sovereignty over the bay. In 1861 Captain Bickford, R.N., had declared Inyak and Elephant islands British territory; an act protested against by the Lisbon authorities. In 1872 the dispute between Great Britain and Portugal was submitted to the arbitration of M. Thiers, the French president; and on the 19th of April 1875 his successor, Marshal MacMahon, declared in favour of the Portuguese. It had been previously agreed by Great Britain and Portugal that the right of pre-emption in case of sale or cession should be given to the unsuccessful claimant to the bay. Portuguese authority over the interior was not established until some time after the MacMahon award; nominally the country south of the Manhissa river was ceded to them by the Matshangana chief Umzila in 1861. In 1889 another dispute arose between Portugal and Great Britain in consequence of the seizure by the Portuguese of the railway running from the bay to the Transvaal. This dispute was referred to arbitration, and in 1900 Portugal was condemned to pay nearly £1,000,000 in compensation to the shareholders in the railway company.

DELAMBRE, JEAN BAPTISTE JOSEPH (1749-1822), French astronomer, was born at Amiens on the 19th of September 1749. His college course, begun at Amiens under the abbé Jacques Delille, was finished in Paris, where he took a scholarship at the college of Plessis. Despite extreme penury, he then continued to study indefatigably ancient and modern languages, history and literature, finally turning his attention to mathematics and astronomy. In 1771 he became tutor to the son of M. d’Assy, receiver-general of finances; and while acting in this capacity, attended the lectures of J. J. Lalande, who, struck with his remarkable acquirements, induced M. d’Assy in 1788 to install an observatory for his benefit at his own residence. Here Delambre observed and computed almost uninterruptedly, and in 1790 obtained for his Tables of Uranus the prize offered by the academy of sciences, of which body he was elected a member two years later. He was admitted to the Institute on its organization in 1795, and became, in 1803, perpetual secretary to its mathematical section. He, moreover, belonged from 1795 to the bureau of longitudes. From 1792 to 1799 he was occupied with the measurement of the arc of the meridian extending from Dunkirk to Barcelona, and published a detailed account of the operations in Base du système métrique (3 vols., 1806, 1807, 1810), for which he was awarded in 1810 the decennial prize of the Institute. The first consul nominated him inspector-general of studies; he succeeded Lalande in 1807 as professor of astronomy at the Collège de France, and filled the office of treasurer to the imperial university from 1808 until its suppression in 1815. Delambre died at Paris on the 19th of August 1822. His last years were devoted to researches into the history of science, resulting in the successive publication of: Histoire de l’astronomie ancienne (2 vols., 1817); Histoire de l’astronomie au moyen âge (1819); Histoire de l’astronomie moderne (2 vols., 1821); and Histoire de l’astronomie au XVIIIe siècle, issued in 1827 under the care of C. L. Mathieu. These books show marvellous erudition; but some of the judgments expressed in them are warped by prejudice; they are diffuse in style and overloaded with computations. He wrote besides: Tables écliptiques des satellites de Jupiter, inserted in the third edition of J. J. Lalande’s Astronomie (1792), and republished in an improved form by the bureau of longitudes in 1817; Méthodes analytiques pour la détermination d’un arc du méridien (1799); Tables du soleil (publiées par le bureau des longitudes) (1806); Rapport historique sur les progrès des sciences mathématiques depuis l’an 1789 (1810); Abrégé d’astronomie (1813); Astronomie théorique et pratique (1814); &c.

DELAMERE (or De la Mer), GEORGE BOOTH, 1st Baron (1622-1684), son of William Booth, a member of an ancient family settled at Dunham Massey in Cheshire, and of Vere, daughter and co-heir of Sir Thomas Egerton, was born in August 1622. He took an active part in the Civil War with his grandfather, Sir George Booth, on the parliamentary side. He was returned for Cheshire to the Long Parliament in 1645 and to Cromwell’s parliaments of 1654 and 1656. In 1655 he was appointed military commissioner for Cheshire and treasurer at war. He was one of the excluded members who tried and failed to regain their seats after the fall of Richard Cromwell in 1659. He had for some time been regarded by the royalists as a well-wisher to their cause, and was described to the king in May 1659 as “very considerable in his country, a presbyterian in opinion, yet so moral a man.... I think your Majesty may safely [rely] on him and his promises which are considerable and hearty.”[1] He now became one of the chief leaders of the new “royalists” who at this time united with the cavaliers to effect the restoration. A rising was arranged for the 5th of August in several districts, and Booth took charge of operations in Cheshire, Lancashire and North Wales. He got possession of Chester on the 19th, issued a proclamation declaring that arms had been taken up “in vindication of the freedom of parliament, of the known laws, liberty and property,” and marched towards York. The plot, however, was known to Thurloe. It had entirely failed in other parts of the country, and Lambert advancing with his forces defeated Booth’s men at Nantwich Bridge. Booth himself escaped disguised as a woman, but was discovered at Newport Pagnell on the 23rd in the act of shaving, and was imprisoned in the Tower. He was, however, soon liberated, took his seat in the parliament of 1659-1660, and was one of the twelve members deputed to carry the message of the Commons to Charles II. at the Hague. In July 1660 he received a grant of £10,000, having refused the larger sum of £20,000 at first offered to him, and on the 20th of April 1661, on the occasion of the coronation, he was created Baron Delamere, with a licence to create six new knights. The same year he was appointed custos rotulorum of Cheshire. In later years he showed himself strongly antagonistic to the reactionary policy of the government. He died on the 8th of August 1684, and was buried at Bowdon. He married (1) Lady Catherine Clinton, daughter and co-heir of Theophilus, 4th earl of Lincoln, by whom he had one daughter; and (2) Lady Elizabeth Grey, daughter of Henry, 1st earl of Stamford, by whom, besides five daughters, he had seven sons, the second of whom, Henry, succeeded him in the title and estates and was created earl of Warrington. The earldom became extinct on the death of the latter’s son, the 2nd earl, without male issue, in 1758, and the barony of Delamere terminated in the person of the 4th baron in 1770; the title was revived in 1821 in the Cholmondeley family.
