To: Laboratory From: Washington Field Re: 279A-WF-222936-USAMRIID, 2/06/2008 analyses of the samples and powders. Compositional analysis of the microbial samples should include assessment for the presence of elements of interest to the AMERITHRAX Investigation, to include, but not limited to Silicon, Oxygen, Tin, and Iron. If elements are identified, the ultra- structural location of the elements should be elucidated. Should the structure of the unidentified powders be consistent with dried microbial organisms it is requested that they be analyzed for the presence of elements of interest to the AMBRITHRAX Investigation along with ultra-structural mapping within the organisms. , Tt is requested that representative images of each sample be prepared, such that visual comparisons can be made to images of evidentiary ‘materials and historical images obtained throughout the course of the AMERITHRAX Investigation. — . A spreadsheet prioritizing the samples for analysis is attached to and considered a part of this document.
