EDITORIAL
Leslie Ettre of Perkin-Elmer and C. Horvath of Yale University trace the historical "Foundations of Modern Liquid Chromatography" 422 A
Professor Laitinen calls attention to the increased emphasis in analytical chemistry to biological systems and suggests that biochemists as well as analytical chemists in the early stages of their career might well consider the opportunities in this field for interdisciplinary research 609
INSTRUMENTATION Alan G. Marshall and Melvin B. Comisarow of the University of British Columbia discuss the advantages of Fourier and Hadamard transform spectroscopy over conventional scanning methods by analogy to the correct use of a doublepan balance 491 A

Our cover illustrates our REPORT, "Foundations of Modern Liquid Chromatography," by L. S. Ettre and C. Horvath, page 422 A. The design is based on a color drawing in the frontispiece of the book, "Chromatographic Adsorption Analysis," by Harold H. Strain, published in 1942 by Interscience. Represented is the separation of carotenes by adsorption of petroleum ether extracts of leaves on a magnesia column. At the top of the column are xanthophylls and chlorophylls; in the center, beta-carotene; and bottom, alpha-carotene. Strain himself was a pioneer in the introduction of modern liquid chromatography in the U.S. In the REPORT, modern liquid chromatography is shown to have evolved from pioneering activities on the art of chromatography in the 1930's and 1940's and from the development of the theory of chromatography in the 1940's and 1950's. These historical developments are placed in the scientific and political perspectives of the times.
