MERNOMUS, Henry, son of the preceding, was born at Lubeck in 1638. After acquiring the elements of literature in his native place, he went, in 1655, to the university of Helmsstadt, where he applied himself to philosophy and medicine, and afterwards studied at Groningen, Franeker, and Leyden. On his return to Germany, he undertook a tour through Italy, France, and England; contracted an acquaintance with the learned wherever he went; and took his degree in physic as he passed through Angers, in 1663. In 1664, he obtained a professorship of physic at Helmsstadt, to which, in 1678, were joined the professorships of history and poetry, which he held until the time of his death, in March 1700. Besides a number of works relating to his own profession, he published Scriptores Rerum Germanicarum, 1688, in three vols. folio; an useful collection which had been commenced but not completed by his father.
