the lymphatics running from the nostrils toward the submaxillary 

 glands. The predominance of the streptococcus in, and the entire 

 absence of the glanders bacillus from the discharge and inflamed 

 mucosa are conclusive. In the regular cases in which the sub- 

 maxillary lymph glands are implicated, both right and left are 

 usually involved, though not to the same degree, the exudate 

 fills not only the gland tissue, but a large amount of the sur- 

 rounding connective tissue as well, there is a great accumulation 

 of lymphoid cells, and more or less extensive pus cavities, con- . 

 taining usually a white, creamy product. In the early stages the 

 glands may be hard and nodular, as in glanders, but this condition . 

 is very transient, so that the rule is to find an extensive surrounding 

 exudation filling up the whole intermaxillary space, and having a 

 great abundance of small round cells with double or triple nuclei. 

 In the older cases there is usually the open abscess, and if the 

 case is an indolent one there may be extensive organization of 

 the exudate with formation of dense, fibrous tissue. In some 

 instances the nasal sinuses are filled with muco-pus. 



When lesions extend farther implicating the pharynx and 

 larynx, the mucosa of these parts shows the same redness, con- 

 gestion, cloudy swelling and desquamation with, in some in- 

 stances, small, submucous abscesses, and in others extensive in- 

 filtration of the submucosa with lymph so as to narrow or even 

 close the lumen of the larynx. The guttural pouches may be 

 filled with pus though this is far from constant. The pharyngeal 

 lymph glands, are nearly always involved and often the lymph- 

 gland in the parotid so that a general infiltration of the surround- 

 ing parts is met with. 



If the chest is implicated there is congestion of the bronchial 

 mucosa, engorgement of the smaller bronchia, air sacs and cells 

 with pus, collapse, carnifaction or congestion of lobules, in some 

 cases pulmonary abscess, and, finally, swelling and not infre- 

 quently abscess of the bronchial glands. Pleurisy is a not un- 

 common accompaniment, appearing it may be as a simple exten- 

 sion, from the lung, or, in the worst forms, from rupture of me- 

 diastinal or glandular abscesses into the cavity and severe infec- 

 tion of the entire pleural walls. The pericardium is exceptionally 

 involved and coagula on the tricuspid valves have been met with 

 (Zschokke).
