Plate I. 



a Markedly distended epimysium, showing the wall of infiltrating leuco- 

 cytes along its border. 



a' The fibrinous exudate containing very few cells in the central part of 

 the distended epimysium. 



b An obturating white thrombus occluding a vein in the perimysium. 



c New-forming connective tissue causing a hyperplasia of the perimysium. 



d A partly occluded artery in the septa. 



e A mixed parietal thrombus in an enormously engorged vein of the septum. 



f An enormously congested vein of the septum, showing the numerous leuco- 

 cytes in the blood; also their migration through the degenerated wall 

 of the vessel. 



g The atrophied and degenerating muscle fibers throughout the specimen. 



h Hyperplastic perimysium containing a few leucocytes but mostly new- 

 forming connective tissue. 



Plate II. 



a Fibrinous exudate containing very few cells, located in the central part 

 of the markedly distended epimysium. 



b The well of infiltrating leucocytes along the edge of the markedly dis- 

 tended epimysium. 



c Vein containing blood wdth numerous leucocytes. In the walls of the ves- 

 sel are migrating leucocytes. 



c' New-forming connective-tissue cells with some migrating leucocytes. 



d Hyperplastic endomysium composed mostly of new-forming connective 

 tissue, with a few migrating leucocytes. 



e Vacuoles left where the muscle fibers have completely disappeared. 



f Atrophied muscle fiber, showing space it should occupy, and the hyper- 

 plastic endomysium around it. 



Plate III. 



a Wall of leucocytes along the edge of the epimysium. 



b New-forming blood vessel in the hyperplastic endomysium. 



c One of the many vacuoles where the muscle fibers have entirely dis- 

 appeared. 



d New-forming connective tissue with a few migrating leucocytes forming 

 the hyperplastic endomysium. 



e Two of the numerous atrophied and degenerating muscle fibers. 



Plate IV. 



a Congested blood vessel in the subcutaneous tissue, showing numerous leu- 

 cocytes in the blood. 



b Zone of new-forming connective tissue around the blood vessel. 



c New-forming blood vessels distended with blood in the connective-tissue 

 zone. 



d Zone of leucocytes, principally polynuclears with a few round cells. 



e Zone of broken down leucocytes and cell detritus. 



f Fibrin from the inflammatory exudate.
