During 1710 Boerhaave lectured on the Methodus discendi medicinam. In 1726 the first edition was published from notes taken at his lectures but without his permission. Lindeboom, Bibliographia Boerhaaviana (1959) No. 91, describes this edition as having 457pp., with one figure, but does not name a publisher. Another edition with 458pp. was issued by J. F. Bernard in Amsterdam, also in 1726, and a third printing appeared in Venice in 1727. As Boerhaave had the habit of constantly citing classic works on various subjects during his lectures, this book served partly as a kind of brief guide to the major literature on the topics it covered.
