Specimen has been subject to four independent analytical passes. Two report ordinary magnetite within experimental tolerance; two report results consistent with neither magnetite nor any related ferrimagnet. The discrepancy reproduces on intercomparison of the same instrument with the same operator on different days. The record is held open.
