corpuscles and indistinct pulp spaces crowled with red blood cor- 

 puscles and nucleated cells. Most of the latter are small mononu- 

 clears. Large mononuclear, hnrnphatic endothelia are not very 

 numerous, a few of them containing the remnants of red blood 

 corpuscles. A moderate number of plague bacilli are present in the 

 sections. The vessels of the kidneys, including the glomerular 

 capillaries, are greatly engorged and small areas of blood extravasa- 

 tion, both subcapsular and interstitial, are seen here and there. 

 The uriniferous tubules show a loss of epithelium and advanced 

 cloudy swelling with granular material in the tubular lumina. 

 The capsules of Bowman are not thickened. There is no prolifera- 

 tion of the glomerular epithelium. The interstitial connective 

 tissue is cedematous and here and there shows 'some finely granular 

 material deposited between the tubules. Plague bacilli are not 

 seen in the renal sections. The suprarenals show an enormous 

 engorgement of the interfascicular capillaries. In the liver one 

 sees great dilatation of the capillaries, and veins with an increased 

 number of leucocytes in the former. The parenchyma cells are 

 both finely and coarsely vacuolated. One of the three pieces of 

 of liver which was taken for microscopic examination shows a 

 very small focus of coagulation necrosis. Here the parenchyma 

 cells are completely necrotic and in fact indistinguishable. A few 

 small mononuclears are found scattered over the necrotic focus, 

 which also shows a reticular, finely fibrillar matrix. At the very 

 margin of the focus is seen a .multinuclear giant cell, with a 

 crescentic arrangement of its nuclei. The large cell has the 

 typical appearance of a giant cell in tuberculosis. There are also 

 encountered in this area a very few cells approaching the type of 

 the epithelioid cells of the bacillar tubercle. The larger necrotic 

 focus found in the center of the right lobe likewise consists of 

 cells in a state of complete coagulation necrosis and finely granular 

 material. At the periphery of the mass there is a zone of cellular 

 infiltration composed of small lymphoid cells, mixed with consider- 

 able numbers of ordinary pohTiuclears. Eosinophiles are not seen. 

 In the interior of the necrotic mass there are found a number of 

 reticula of typical fibrin which gives Weigert's reaction. It is in 

 connection with this fibrin and in its neighborhood that great 

 numbers of shell-like plague bacilli are encountered. No plague 

 bacilli are found in other parts of the hepatic sections. Neither 

 in the small tubercle nor in the larger necrotic focus could any
