BIOGRAPHICAL SKETCHES, 51 It is said that when Sam was in London, on one occasion he was advised to show himself for money, and that although he declined exhibiting himself in his own character, he so far acted on the hint as to dress in female attire, and advertise as ‘‘ The remarkably tall woman.” By this ingenious expedient, Sam became so well furnished with cash that his expenditure attracted the notice of his Colonel, who being curious to ascertain in what way he had obtained his supplies, interrogated Sam, who candidly disclosed the fact, and in this way the secret transpired. Sarn was once persuaded to appear on the stage, whilst in the service of his late Majesty, at the request of his Royal Master. This took place at the Opera-House in the Haymarket, then occupied by the Drury Lane Company. upon occasion of the representation of a dramatic entertainment, called “ Cymon and Iphigenia,” and in which he acted the appropriate part of Hercules.’ Numberless anecdotes are told of M‘Donald, illustrative of his great strengkh. On one occasion, having been challenged by two soldiers of his own regiment on the understanding that he was to fight both at once, Samuel agreed, but said, as he had no quarrel with them, he should wish to shake hands with them before they began. One of the combatants instantly held out his hand. Samuel took hold of it, but instead of giving it the friendly shake expected, he used it as a Iever to raise its owner from the ground, when he swung him round as he would a cat by the tail, and threw him to a great distance. The other combatant, not admiring this preliminary process, took to his heels. Many feats of strength similar to this are, as already mentioned, recorded of him. While in Edinburgh, Sam occasionally patronised Geordie Cranstoun (see No. 19) to whose singing he took much pleasure in listening. He was nevertheless much displeased to find himself associated with him in this Print, which was shown him by Mr. Kay. He remarked to the engraver that he did not choose to be classed with a beggar, and insisted that the little man’s portrait should be expunged. Although this demand was not complied with, the next time that Sarn called on the artist he was in his usual good humour. Sam was six feet ten inches high, four feet round the chest, extremely strongbuilt and muscular, but yet proportionable, unless his legs might be thought even too large for the load they had to bear. No. XXI. MAJOR FISHER. THIS gentleman, represented as giving the word of command, was an officer in the 55th Regiment of Foot, which was in Edinburgh in 1790. Both officers and men conducted themselves with great propriety while there. 1 Gentleman’s Magazine, voL Ixxii. p. 478.
52 BIOGRAPHICAL SKETCHES. No. XXII. DR. JOSEPH BLACK. DR. BLACK was born in France, on the banks of the Garonne, in 1728. His father, Mr. John Black, was a native of Belfast, in Ireland, but his ancestors were originally from Scotland. Mr. Black had settled in Bordeaux as a winemerchant, where he married a daughter of Mr. Robert Gordon of Hillhead, in Aberdeenshire, who also resided at Bordeaux, and was engaged in the same trade. At the age of twelve, young Black was sent to his relations in Belfast for his education, and he accordingly attended the schools of that town. In 1746 he entered the University of Glasgow, where he was very early patronised by Mr. Robert Dick, Professor of Natural Philosophy, and speedily became the intimate companion of his son, who, as well as his youthful friend, had already given a decided preference to physical knowledge. During the course of the same year in which he went to college, Dr. Cullen commenced his illustrious career as lecturer on chemistry in the University of Glasgow, and his fame quickly spread through the city of Glasgow. His class, besides being filled with regular students, was attended by many gentlemen who had no idea of prosecuting professionally the study of medicine. Dr. Cullen, whoin every situation which he held either in Glasgow or in Edinburgh, made it a point to cultivate an acquaintance with those who attended his lectures-uniformly treating them with respect, but from the natural openness and generosity of his temper, never keeping them at a distance-was accessible at all times, and took cognisance of the progress of their studies. He became early acquainted with young Black, and, perceiving the bent of his genius, strongly impressed upon him the propriety of prosecuting with ardour the cultivation of that field of science upon which he had just entered. In a short time he was advanced to be Dr. Cullen’s assistant in the performance of experiments ; and by the extraordinary neatness and address which he displayed in this department, he essentially contributed to increase the eclbt of the Professor’s lectures, He repaired to Edinburgh to finish his medical studies, and in 1751 was enrolled as a student of medicine, Whilst there, he resided with his cousingerman, Mr. Russell, Professor of Natural Philosophy in that University. The usefulness of this seminary as a medical school was then only beginning to be known, but the reputation of its teachers had already spread through various parts of the world. During three sessions he attended all the necessary classes, and took the degree of Doctor of Medicine in 1754. On this occasion it is customary in Edinburgh to print a thesis, in the Latin language, on some subject connected with medical science. Dr. Black chose for his theme “ The Acid arising from Food, and Magnesia Alba,” in which was contained
