 of resistance on the part of the organism to various forms of injury, in- 

 fection, etc. 



Lymph-Nodes and Nodules. The pharyngeal, thoracic, and abdominal

often infiltrating the surrounding tissue. There may be hyperplasia of 

 the tonsils, of the cervical, mediastmal, axillary, and abdominal lymph - 

 nodes, as well as of the lymphatic tissue of the gastro- intestinal canal 

 (Fig. 202). 



The thymn.i may be congested and large and soft from hyperplasia. 

 It sometimes evidently exerts such pressure on the adjacent bronchi and 

 large vessels as to lead to death. 



The spleen may be moderately enlarged from hyperplasia, especially 

 of theTymphoid tissue of the Malpighiau bodies, and it may be con- 

 gested. '
