air. The bronchi show a swollen and congested mucosa, and con- 

 tain a moderate amount of viscid mucus. The mucosa of the 

 trachea and larj'nx is congested, particularly that of the epiglottis. 

 The spleen is small and its capsule slightly wrinkled and rather 

 soft in consistency. On section the trabeculse are well marked, the 

 Malpighian bodies are indistinguishable and the soft pulp soft and 

 dark brownish-red. The kidneys are normal in size; their capsules 

 are smooth, rather dull, and purplish-blue. On section the surface 

 is grayish-white, and the vessels considerably injected -and 

 prominent. The mucosa of the pelves is smooth and-hyperemic. 

 Liver : The capsule is smooth and purplish-blue with some grayish- 

 white. On section the veins discharge a good deal of blood; the 

 surface is smooth and dull brownish-yellow. Here and there a 

 pale gra}^ soft necrotic focus of small size is seen. The gall 

 bladder and ducts are normal. The gastric and intestinal mucosa 

 is hyperemic, the former showing a moderate number of small 

 hemorrhagic spots. The lymph glands in general are not much 

 changed, except the right superficial cervical glands, which are 

 swollen, soft, oedematous, and highly congested, but not diffusely 

 hemorrhagic. 



Anatomical diagnosis. — Congestion and oedema of the lungs; 

 congestion and parenchymatous degeneration of the kidneys; sub- 

 serous and submucous hemorrhages; right cervical bubo. Plague. 



Smears from the cervical glands of the right side show numerous 

 plague bacilli as well as numerous delicate, small streptococci. 

 Culture tubes inoculated from the cervical glands and from the 

 spleen developed a typical plague growth. No streptococci were 

 found in the cultures. 



Microscopic examinations. — The capsule of the cervical glands is 

 thickened, and the connective tissue at the hilum much increased. 

 The vessels of the capsule and the hilum are dilated and much con- 

 gested. The entire substance of the glands is traversed by dilated, 

 densely filled vessels; the differentiation into follicles is almost 

 completely lost, the medullar}^ cords are no longer distinguishable. 

 The peripheral Ijonph sinus is dilated and contains a number of 

 mononuclear cells and a good deal of granular material. The 

 blood vessels, though dilated and much congested, show no marked 

 changes in their walls, except some thickening of the adventitia; 

 they do not contain any fibrin but are densely crowded with
