**Although the date found dead was listed as 1/9/74 on the gross pathology sheet, the "Tissue Masses & Deaths" book listed this date as 7/25/73.

The gross pathology sheet for one of the above animals, F6HF, described a tissue mass measuring 5.0 X 4.5X2.5 cm.  This tissue mass was first observed on 8/24/73 according to the pathology sheet (Exhibit #79), the observation records (Exhibit #70), and the palpation record in the "Tissue Masses and Deaths" book (Exhibit #65).  The submission to FDA (Exhibit #8) reported no tissue mass and the animal was excluded from the study due to marked autolysis.

In addition to the above twenty animals that were excluded from the study, many other animals exhibited marked autolysis.  For example, D27LF, M25CF, and H12CF are all described grossly in the submission to FDA as follows; "all organs examined grossly were markedly autolyzed".

Records for approximately 30 animals showed substantial differences between gross observations on pathology sheets, when compared with the individual pathology summaries submitted to FDA.  Following is a detailed comparison of ten of these.  (Copies of all the gross pathology sheets, and the pathology summaries submitted to FDA are attached as Exhibits #78, #79, and #86).

Dr. Stejskal told us that the other pathologist (Dr. Joseph Smith) who made microscopic evaluations of the slides, came from a hospital background (human pathology) and therefore his descriptions and terminology were a little bit different than one would expect from a veterinary pathologist.
