in good focus. 

 Fig. 2. Fresh smear from Puragonimus abscess of spleen, showing eggs. 

 V, figs. 1-9, and Plate VI, figs. 1-9, represent 18 selected specimens from

 eggs; otherwise but slight change in the tissues. X 35. 

 Fig. 2. From intestinal Avail, tissue containing eggs, with cellular 

 infiltration. X 35.
