    in square yards per hundredweight the following : Oxide of zinc, 870; red lead, 424; white lead, 614 to 806; the prices per hundredweight in shillings being 46, 28, and 28 to 32, respectively; and the estimated numbers of tons required for painting the surfaces in twenty years being 4, 4, and 5 to 6. When the proposed interdiction of lead paints was being discussed in the French Legislative Assembly, opinions of experts upon the relative merits of zinc and lead were quoted. It was stated that the naval engineers of Rouen, after three years' experience of both pigments, preferred zinc to lead, since the white colour of the paint did not blacken under the influence of sulphur. Equally favourable to zinc were the opinions of the naval engineers of Bordeaux. At the request of the French Government, experiments dealing with the covering and enduring power of the two paints were carried out at the Annexe of the Pas- teur Institute, Paris. A Commission nominated by the Society of Public Medicine and of Hygiene undertook a series of experiments with the object of comparing surfaces painted with zinc and lead bases. The Commission was composed of Dr. L. Martin, M. Livache (a chemist), and M. Vaillant (an architect), along with Messrs. Mauger, Wernet, and Rigolet, representing the building trades of Paris.
