Pursuant to this contract, Dugway also sent Ba Ames in a paste form, which was received’ by both Ivins and = a documented by Ivins in a lab notebook. This’ notebook bé6 was ehtitled "USAMRIID Notebook 4010". Seven batches of wet bIC slurry were shipped to Ivins from Dugway between April 23, 1997 and October 24, 1997. The seventh batch, shipped October 24, 1997, was deemed by Ivins to be so "dirty" that the spores were autoclaved. Ivins combined purified batches of the first six shipments into final lots with other Ames spores from Ivins' collection, which were then all combined into a final lot on October 22, 1997. This lot was called RMR 1029. RMR 1029 was dispersed into two equal lots, 500 milliliters per lot, and stored at 2-8 degrees Celsius in polycarbonate screw-capped flasks in the B3 cold room in Building 1425. Ivins described the spores as "...highly purified. They are >95% unclumped, single, refractile spores." Ivins advised that one milliliter or less of the Dugway material could be taken and wouldn't be missed. Details on Ivins' processing of the Dugway batches of spores, and their combination to form RMR 1029, are documented in a separate
