“ For this work Dillen himself executed 324 plates, and it was described by Linnaeus, who spent a month with him at Oxford in 1736, and afterwards dedicated his Critica botanica to him, as “opus botanicum quo absolutius mundus non vidit.” In 1734 he was appointed Sherardian professor of botany at Oxford, in accordance with the will of W. Sherard, who at his death in 1728 left the university £3000 for the endowment of the chair, as well as his library and herbarium. Dillen, who was also the author of an Historia muscorum (1741) , died at Oxford, of apoplexy, on the 2nd of April 1747. ”
