prepare them. These samples were made in June 1987. The Ames made
by Re in 1987 was produced in May 1987, and the
paper documentation IVINS has on this sample is in their

at one time stored frozen in the chest freezer in B3. If the

samples were present when SA[_ inventoried IVINS' Ames
(meaning all of the Ames in Suite B3), then the samples should be

The 1989 subculture is the one IVINS made himself from
the 1981 original slant.

IVINS does not recall how the 1985 and 1987 samples are
labeled. He does not believe they are labeled with the dates of
production. IVINS just routinely identified the samples by their
location in his laboratory.

Regarding samples transferred between USAMRIID and Dugway
Proving Grounds, IVINS' shipment request form for the October 1992
Ames shipment to Dugway showed a concentration of 8 x 10° spores
per milliliter (ml). This concentration matches that shown on a
folded page stapled onto page 56 of laboratory notebook #2064. The
entry on the folded page which shows 8.3 x 10° spores per ml is
listed as a Leighton-Doi preparation of Ames from May 1987. That
sample was the one prepared byf sd nrc by IVINS.

Therefore, IVINS believes the sample of Ames he sent to Dugway in
1992 was the May 1987 (preparation.

The 1997 shipment of Ames to Dugway was spores from RMR
1030 to be used to produce the spores for RMR 1029. After looking
in his laboratory notebook, #4010, IVINS provided the concentration
of RMR 1030 as 2.5-2.9 x 10° spores per ml. It was a liquid

shipping request form for the 1997 Dugway shipment of Ames. If the
concentration on the form is from 1-3 x 10% spores per ml, and if
the forms shows that the sample was in a liquid state, IVINS would

be certain that the 1997 shipment was RMR 1030. He could not
locate this form in his office during the interview.
