ously due to other causes than the waters. He recommended olive oil for the treatment of round worms in children, in 'Observations on the Case of the Norfolk Boy' in 1758, and agreed with Sir George Baker (1722-1809) [q. v.] in a letter as to the effect of lead in cider (London Med. Trans, i. 202). In 1775 he published a letter to William Heberden (1710-1801) [q. v.] on angina pectoris, which contains one of the earliest English reports of a post-mortem examination on a case of that disease. He had noticed calcification of the aortic valves and of the aorta itself. He died at Bath on 27 June 1776. He married Catherine, youngest daughter of Martin Sandys, a barrister, uncle of Samuel Sandys, first baron Sandys [q. v.] His son, Martin Wall [q. v.], collected his works into a volume entitled ' Medical Tracts,' which was published at Oxford in 1780. The preface mentions that ' an unremitting attachment to the art of painting engaged almost every moment of his leisure hours from his infancy to his death.' His portrait hangs in the board-room of the Worcester Infirmary. His picture of the head of Pompey brought to Caesar is at Hagley, Worcestershire, and there is another in the hall of Merton College, Oxford.

WALL, JOSEPH (1737–1802), governor of Goree, born in Dublin in 1737, was a son of Garrett Wall of Derryknavin, near Abbeyleix in Queen's County, who is described as 'a respectable farmer on Lord Knapton's estates.' At the age of fifteen Joseph Wall was entered at Trinity College, Dublin, but preferred an active career to the life of a student; and about the beginning of 1760, having entered the army as a cadet, he volunteered for foreign service. He distinguished himself at the capture of Havana in 1762, and at the peace returned with the rank of captain. He next obtained an appointment under the East India Company, in whose service he spent some time at Bombay. In 1773 he was appointed secretary and clerk of the council in Senegambia, where he was imprisoned by Macnamara, the lieutenant-governor, for a military offence, with circumstances of great cruelty. He afterwards obtained 1,000l. damages by a civil action. After his release he returned to Ireland ' to hunt for an heiress.' He found one in the person of a Miss Gregory whom he met at an inn on his father's estate. But he pressed his suit 'in a style so coercive' that she prosecuted him for assault and defamation, and 'succeeded in his conviction and penal chastisement.' Wall had some time previously killed an intimate friend in one of his frequent 'affairs of honour,' and he now transferred himself to England. He divided himself between London and the chief watering-places, spending his time in gaming and amorous intrigues. At length, finding himself in embarrassed circumstances, he in 1779 procured through interest the lieutenant-governorship of Senegal or Goree, as it was generally called, with the colonelcy of a corps stationed there. Goree was the emporium of West African trade; but the governorship was not coveted, not only because the climate was bad, but on account of the garrison being composed of mutinous troops sent thither for punishment, and recruited from the worst classes. On the voyage out Wall had a man named Paterson so severely flogged that he died from the effects. The occurrence is said to have so affected his brother, Ensign Patrick Wall, as to have hastened his death, which took place soon after he reached Goree.
After having been governor and superintendent of trade for rather more than two years, Wall's health gave way, and he prepared to leave the colony. On 10 July 1782 a deputation of the African corps, who had been for some time on a short allowance, waited on the governor and the commissary to ask for a settlement. It was headed by a sergeant named Benjamin Armstrong. Wall, who appears to have been in liquor, caused the man to be arrested on a charge of mutiny, and a parade to be formed. He then, without holding a court-martial, ordered him to be flogged by black slaves, which was contrary to military practice. Armstrong received eight hundred lashes, and died from the effects some hours afterwards. On Wall's return to England several charges of cruelty were laid against him by a Captain Roberts, one of his officers, and he was brought before the privy council and a court-martial; but the charges were for the time allowed to drop, as the ship in which the witnesses were returning was believed to have been lost. He then retired to Bath. Afterwards, upon the arrival of the principal witnesses, two messengers were sent to bring him to London, but Wall escaped from them at Reading, and thence to the continent. A proclamation offering a reward of 200l. for his apprehension was issued on 8 March 1784. He spent the succeeding years in France and Italy, living under an assumed name. In France he
