Any teacher interested in registering an undergraduate chemistry student in one of the research projects should write to the dirertor of that project. The National Cooperative Undergraduate Chemical Research Program has been mailing an annual catalogue to about 150 colleges. This article replaces the 1952 catalogl~e. Any teacher interested in directing a new project should write to one of the authors of this article as soon as possible, since a project is listed under the direction of the first person to request it. Previous catalogues carried a list of "Projects in Search of Directors." Such a list can be obtained upon request. An outline of any project for the 1953 catalogue must be sent to one of the authors by January 15, 1953.
