LAUFFER, Ph.D.* A lecture delivered at the 15th December, 1955, meeting of the Society in New York Dr. Lauffer surveys the subjects of the articles published in the "JournaP' showing the development of a "cosmetic chemistry." He welcomes the increasing interest in cosmetic science, surveys some branches of that science and suggests fields for useful future work where present knowledge is inadequate. THE TENTH anniversary of our Society seems a fitting occasion for a bird's-eye view ooe the Society's scientific and technological activities, and for an attempt to describe and delineate the body of cosmetic chemistry that is gradually taking form. A study of the papers presented at meetings of the Society will give an indication of our members' interests. The first five volumes of the Journal of the Society of Cosmetic Chemists include substantially all the papers presented at the meetings of the American Society, the British Society, and the Chicago Chapter, from 1945 to mid- 1954. These five volumes contain 170 papers, by 172 different individuals. One author's name appears on five papers, two on four, five on three, and eleven on two. * The George W.
