of the stronger contractions of the myonemes at the inner edge 

 of the organism with successively smaller contractions of the 

 myonemes toward the outer (greater) curvature, where there 

 would be a ring of relaxed myonemes. The axial line of the body, 

 where, judging from the action of the granules, the movement is 

 least, would be, according to this arrangement, a neutral area, 

 neither contraction nor relaxation of the myonemes occurring 

 within it.

Living Leucocytozoon museuli. 



Diagrams of a young intra-corpnscular parasite observed in the living condition 

 for seven hours. 



In these diagrams the cytoplasm of the parasite is represented by small dots, more 

 closely aggregated where the protoplasm stained more deeply. Vacuoles are left 

 clear. The chromatin of the parasite is represented black in G— K, and the nucleus 

 of the leucocyte is shown by shaded lines. The outline of the leucocyte is indicated 

 hy a circular area. 



The nucleus of the leucocj-te is not yet much displaced by the parasite, and no 

 marked hypertrophy of the host-cell has yet occurred. 



The time required for the assumption of the various forms
