Ad 1: Posthumously published first edition of Rembert Dodoens's 127 Latin lectures on medicine, edited and extensively annotated by Sebastian Egbertsz. de Vrij. Dodoens (1517-1585), the greatest botanist of his age, was appointed professor of medicine at Leiden University in 1582 and delivered the present lectures in 1583 and 1584. He never published them, but they were prepared for publication by his student Sebastian Egbertsz. de Vrij. Much of the material is, of course, of botanical and pharmacological as well as medical interest.
Ad 2: Dodoens's description of 54 remarkable medical case studies from his forty years' experience as a physician, first published together with Dodoens's Historia vitis vinique in 1580 and issued separately in 1581. It originally contained 53 case studies, but Dodoens added one on palpitations in Plantin's 1585 edition.
With contemporary and later inscriptions. Some quires in the appendices to the Medicinalium observationum are slightly browned, and a hole at the foot of its last leaf affects a few words in the index. Otherwise in good condition and only slightly trimmed. Ad 1: Krivatsy 3300; STCN (5 copies); ad 2: Krivatsy 3299; STCN (5 copies).
