Experiments of Macer.
Although Odo or Macer seems to make no original contribution to botany, cites authorities frequently, and speaks often of the ancients or men of old, he also at least once cites “experts”[2520]and we have also seen his belief that the ancients had tested the virtues of plants by experience. This rather slight experimental character of the work is further emphasized in some manuscripts of it, where the title is “Experiments of Macer” and the matter seems to have been rearranged under diseases instead of by herbs.[2521]
