Every chemist, every chemical engi neer should make certain he keeps up to date by: (1) Subscribing and reading those ACS publications which serve his particular field. (2) Examining carefully the ad vertising pages in ACS publica tions, for they contain scientific and technical data second only in importance to the editorial pages. (3) Building up a substantial reference file of manufacturers' literature to provide valuable in formation quickly. Use this handy return card to save yourself time. It will bring information of use to chemists and engi neers in laboratory, pilot plant, and production. The items listed in this special section have been selected by the editors of ANALYTI CAL CHEMISTRY for their value and timeliness in helping you to keep abreast of the latest developments in the field.
