HEMOLYMPH NODES AND ACCESSORY SPLEENS 261 



the conclusions drawn by many observers regarding the forma- 

 tion of hemal nodes. That changes may be produced in lymph 

 nodes by repeated bleeding is also suggested by the studies of 

 Smith indicating a lowering of the resistance of erythrocytes after 

 the withdrawal of blood, but it is more than likely that the 

 amount and frequency of that loss are very important factors 

 in the determination of the character and extent of the changes 

 in lymph nodes, a conclusion which also seems to be amply justi- 

 fied by Freytag's observations.
