A sample of unknown origin of deuteroparaffin (paraffin where the ordinary hydrogen is replaced by deuterium) held in a glass vail. The vial is stored in a 24 cm long wooden block into which a hole was bored. A cork closes the container. The label on the outside of the wooden container appears to indicate that at 730 C the container contained 20 g of paraffin with a density of 0.99. The glass vial inside the wooden container appears to indicate that the material was later repackaged and that only 10.5 g now exist in the vial. The repackaging date was 16/7/1946. The note on the vial also indicates that the deuterium source was Norsk Hydro.
