PRACTICAL MICROSCOPY. 



Small diffuse collections of adenoid tissue have already been seen in 

 many organs. These do not differ essentially from the tissue just 

 described, excepting that there is no definite arrangement of trabeculss 

 and lymph paths, as in the compound lymph node; the lymph simply 

 filters through the reticulum, the same being a part of the lymph- 

 channel system of the tissue in which the adenoid structure may 

 occur.
