Ellery" Subject: INQ error in C14 method Some time ago, I started to read an article about a fundamental miscalculation in the C14 dating method as used to date, which introduced a significant error. Unfortunately, it was in one of those frustrating places (dentist's office or such) where you don't get to finish reading. I have heard no more about this since, and would very much like to find out about it. What is the basis for the error (if it is real)? What magnitude? Is it correctable by recalculation? I would very much appreciate any information that may be offered.

Thieme" Subject: coal contamination I am doing my dissertation on the alluvial chronology of the Wyoming Valley in Pennsylvania. Glacial scour exposed coal seams so I am having to try to avoid coal that occurrs as clasts in some prehistoric as well as historic deposits. Any references on coal contamination (other than the Meadowcroft stuff) would be of interest to me. For example, does delta-13-C reflect the extent to which "old" carbon contaminates a sample?
