222 DESCRIPTION OF PLATES 



PLATE XXXIII 



FIGURES 85 and 86. Two endothelial cells with rickettsia from the surface 

 of the thrombus shown at low power in Plate XIII, figure 37. Autopsy 

 32, death on fourteenth day. Artery of skin. 2,000 diameters. 



FIGURE 87. Artery of skin. Autopsy 7, death on ninth day. The arrow 

 points to a clump of rickettsia bodies. This artery showed very slight 

 lesions. 2,000 diameters. 



PLATE XXXIV 



FIGURE 88. Testis. Autopsy 29, death on fourteenth day. An artery of 

 the tunica with a thrombus. The section passes longitudinally through 

 several endothelial cells which in Figure 89 are shown at high power. 

 600 diameters approximately. 



FIGURE 89. To show many rickettsia in the endothelial cells adjacent to 

 the thrombus shown in Figure 88. There are both the large paired 

 rickettsia and the small forms. 2,000 diameters.
