have the appearance of closely set protuberances, some 

 being so small that the elevation caused by them is 

 scarcely visible, while others are larger, reaching 1 -6 

 inch in diameter. The larger nodules are of a pale 

 or dark yellowish color, while the smaller ones vary 

 in shade from this to the neutral gray of the normal 

 serous membrane. To the touch they give the sensa- 

 tion of small, oval, solid bodies in the wall of the in- 

 testine. The mucous surface presents similar eleva- 

 tions and attached to this over the elevations a number 

 of tapeworms are seen. In the m^^re advanced cases a 

 variable number of small ulcerated depressions, 1-25 

 inch in diameter or less, are seen over the larger 

 nodules caused by sloughin^of the mucous membrane.
