Oxide of zinc as an internal medicine was introduced by Gaubius, who was Professor of Medicine at Amsterdam about the middle of the eighteenth century. It had been known and used under the name of flowers of zinc from Glauber’s time. A shoemaker at Amsterdam, named Ludemann, sold a medicine for epilepsy which he called Luna fixata, for which he acquired some fame. Gaubius was interested in it and analysed it. He found it to be simply oxide of zinc, and though he did not endorse the particular medical claim put forward on its behalf he found it useful for spasms and to promote digestion. END OF VOL. I R.

FOOTNOTES: [1] Schelenz in “Geschichte der Pharmacie,” 1904, has collected a remarkable number of facts and documents illustrative of the development of pharmacy in Germany. He quotes a Nuremberg ordinance of 1350 which forbids physicians to be interested in the business of an apothecary, and requires apothecaries to be satisfied with moderate profits. [2] Dr. Monk gives a copy of the Latin minute in the books of the College referring to this curious recantation. The actual words which Geynes signed were these:--“Ego, Johannes Geynes, fateor Galenum in iis, quae proposui contra eum, non errasse.” [3] “Free Phosphorus in Medicine,” 1874.
