    SEDATIVE ASTRINGENT OINTMENTS. Bismuth. 6. Bismuth oxide gj, oleic acid gviij, white wax To be made in the same way as the oleate of zinc. To form an ointment, equal parts of vaseline, lard, or lanolin must be added. McCall Anderson strongly advocates this for eczema. It may also be made by double decomposition. Boracic Acid. 7. Boracic acid 5ss, benzoated lard §j. It is very important that the boracic acid should be ground into an impalpable powder ; merely rubbing in a mortar is insufficient. Excellent in eczema, and as an antiseptic in wounds and excoriations. Lead. 8. Ung. diachytt (Hebra).—Boil together olive oil *xv, litharge Jiij et 3yj, to a good consistence, and add Jij of oil of lavender. For eczema spread on linen and bind on. A simple way is to melt together equal parts of lead plaister and olive oil. These ointments are really oleates of lead. 9. Solution of the subacetate of lead in.xv to mxxx, vaseline, lanolin, or lard 3j. 10. Lead (carbonate of) gr. 4, glycerine % simple ointment 3. ror erythema (Tilbury Fox.) Zinc. 11 Prepared lard gvj, powdered benzoin Melt together for twenty-four hours at a gentle heat in a closed vessel, and then strain and add oxide of zinc Si Mix and strain. This is Wilson's ung. zinci oxidi benzoatum, and is a well-known remedy for eczema. The ung. zinci B.P. is nearly the same, but with less benzoin. . . 12 Zinc oleate, as devised by Mr. Marshall, was made by dissolving 5] ol oxide of zinc in viij of oleic acid by means of a water bath after they have been mixed for two hours. An equal weight of vaseline is stirred in to make it to the consistency of an ointment. Since my advocacy of it for eczema it has been widely adopted, and is now in B.P. Shoemaker has proposed to have this and other oleates made by double decomposition. A sodium oleate is decomposed by means of a saturated solution of zinc sulphate. The pre- cipitate is boiled out and dried, and then reduced to an impalpable powder like French chalk. One part to 3 of any fatty vehicle is the proportion he recommends. I have used 1 to 7. It makes an excellent ointment, and there is no free oleic acid, and it is therefore an improvement. Bismuth and lead oleates may be made on similar lines. Ung. calamine B.P. for wounds and excoriations. ANTISEPTIC OINTMENTS. Iodoform. 13. Iodoform gr. 3 to 5, vaseline or lard §j. 14. Iodol gr. 3 to 5, vaseline or lard 5j. Both these ointments are valuable for pustular eczema, impetigo contag.osa,
