In John Leyden an unconquerable perseverance was united to remarkable native genius, and a memory of singular retentiveness. Eminent as a linguist, he was an able and accurate philologist; in a knowledge of the many languages of India he stood unrivalled. During his residence in the East, he published a "Dissertation on the Languages and Literature of the Indo-Chinese Nations," in the tenth volume of the "Asiatic Researches," and he left numerous MSS. on subjects connected with oriental learning. He was early a votary of the Muse; and, in youth, was familiar with the older Scottish bards. In April 1795, he appeared in the _Edinburgh Literary Magazine_ as author of an elegy "On the Death of a Sister;" and subsequently became a regular contributor of verses to the periodicals of the capital. His more esteemed poetical productions are the "Scenes of Infancy," and the ballads which he composed for the "Minstrelsy of the Scottish Border." Of the latter, the supernatural machinery is singularly striking; in the former poem, much smooth and elegant versification is combined with powerful and vigorous description. There are, indeed, occasional repetitions and numerous digressions; but amidst these marks of hasty composition, every sentence bears evidence of a masculine intellect and powerful imagination. His lyrical effusions are pervaded with simplicity and tenderness. Like some other sons of genius, Leyden was of rather eccentric habits. He affected to despise artificial manners; and, though frequenting polished circles in Edinburgh, then in London, and afterwards in Madras and Calcutta, he persevered in an indomitable aversion to the use of the English tongue, which he so well knew how to write with precision and power. He spoke the broadest provincial Scotch with singular pertinacity. His voice was extremely dissonant, but, seemingly unconscious of the defect, he talked loud; and if engaged in argument, raised his voice to a pitch which frequently proved more powerful than the strength of his reasoning. He was dogmatical in maintaining his opinions, and prone to monopolise conversation; his gesticulations were awkward and even offensive. Peculiar as were his habits, few of the distinguished persons who sought his acquaintance ever desired to renounce his friendship.[96] In his domestic habits, he was temperate often to abstinence; he was frugal, but not mean--careful, but not penurious. He was generous towards his aged parents; was deeply imbued with a sense of religion, and was the foe of vice in every form. He was of a slight figure, and of middle stature; his countenance was peculiarly expressive of intelligence. His hair was auburn, his eyes dark, and his complexion clear and sanguine. He was considerably robust, and took delight in practising gymnastics; he desired fame, not less for feats of running and leaping, than in the sedate pursuits of literature. His premature death was the subject of general lamentation; in the "Lord
