A WALK IN "NO-MAN'S LAND" 67 "eavesdrop" upon each other's work to an even greater extent than has been the case up to now. Without in the least desiring to minimize the role of the cleansing, conditioning, and make-up preparations in the cosmetic picture, I feel that true scientific developments will continue to come from these borderline territories. Perhaps they will come slowly and laboriously but their results promise to be dramatic. And so I would like to entitle my remarks upon the subject chosen: A WALK IN "NO-MAN'S LAND" By EMiL G. KL^UM^NN, D.Sc., ?ice-President, in charge of Technical Services, Lehn & Fink Products Corp., New York 22, N.Y. FRoM times immemorial, almost up to the beginning of the present cen- tury, the bulk of cosmetic preparations served substantially the purpose of covering the skin with pigment and color. The application of such make- up was carried out twenty centuries ago with the same intention as pro- fessed in a modern piece of advertising copy, viz., "to impart a glow to the skin." Ovid, the Roman poet who lived at the turn of the era says it this way in his Ars Amatoria: "Sanguine quae veto non tuber, arte tuber" which could be translated freely to read "Art will impart a glow to the com- plexion if real blood won't do it." This does not mean, of course, that the Roman woman of Ovid's days was not familiar with what we would call today a line of treatrr ent cosrr etics, compounded from more or less rational formulas. Parenthetically speaking, even the virtues of lanolin were known then as shown by Ovid's reference to "oesypum" described as the "juice drawn from a sheep's unwashed fleece." But again bridging a gap of twenty centuries, Ovid's dictum as to the eventual effect of age upon the complexion has had considerable validity until quite recently. In his poem "De Medicamine Faciei" he has this to say, with lofty resignation: ................ Formam populabitur aetas, Et placitus rugis vultus aratus erit. Tempus erit, quo vos speculum vidisse pigebit, Et yenlet rugis altera causa dolor. Sufficit, et Iongum probitas perdurat in aevum. Perque suos annos hinc bene pendet amor. ("Age will ravage beauty, and the lovely face will be ploughed by wrinkles. The time will come when it will hurt you to look in the mirror, and the resulting grief will become a second cause of wrinkles. But goodness suffices and long endures, and love thrives upon it through the years to come.")
