 Plate XXXV. 



Portion of right lung of lamb, dorsal view. The affected region is the dark col- 

 ored posterior end. It is clearly marked off from the healthy portion. The dark red 

 spot about the middle of the figure is also caused by the worms, but it is exceptional 

 to find these lobes affected in early stages.
