1 Laboratory was operative 1958-1.960; some earlier dates were scrutinized when repub- lished in ref. 77, but further checking has not been possible. Reference standard prior to mid-1959 was 120-yr-old oak, found to be 1% less active (after age-correction) than 0.95 x NBS oxalic acid, but this small difference was ignored (except as noted) in calculating dates.

2 Cross-check sample: Y-94, Gro-271.

3 Cross-check sample: B11-59.

4 A second dating, calculated from oxalic-acid standard.
