Figure 2. — a. Cross section of midgut at 2 h postmortem. The appearance is near normal e.xcept for the "blebing" of the 

 apical ends of some of the epithelial cells (arrows) and a few pyknotic nuclei. 250 X. b. Midgut showing more advanced 

 autolytic change at 2 h postmortem. Some epithelial cells have been sloughed into the gut lumen where an eosinophilic 

 coagulum (C) has formed. 240 X. c. Midgut at 4 h postmortem. Most of the epithelial cells possess pyknotic nuclei, and 

 some of the cells have been sloughed into the gut lumen. 210X. d. Midgut at 8 h postmortem. Sloughed epithelial cells 

 are rounded and are either anucleate or have pyknotic nuclei. An eosinophilic coagulum is present. 160 X . e. Midgut at 24 

 h postmortem. An eosinophilic coagulum is present in the gut lumen as are numerous bacteria. No trace of the gut epithe- 

 lium remains. The muscle and tibrocyle cells of the gut wall are anucleate. 190 X. f. Site of midgut at 48 h postmortem. 

 Bacteria and debris have filled the gut lumen. Only fibrous elements of the gut wall remain. 150 X .
