Abstract
All samples processed from November 1971 through January 1973 at the Illinois State Geological Survey Radiocarbon Dating Laboratory are reported here. The benzene liquid scintillation technique was used. Laboratory procedures used were the same as those reported by Coleman (1973), with the exceptions that bone collagen was separated by the Longin (1970; 1971) technique and acetylene was trimerized to benzene as described by Coleman, et al (1972).
