i, Host-cell and reticular parasite, the latter forming stellate subdivisions (x 1,600 

 diameters) ; 2, Leydenia gemmipara of Schaudinn (copied from A. Lang) ; 

 3, A parasite subdividing after the manner of bird's-eye bodies i.e., without 

 the appearance of chromatin as such ; 4, (?) microgamete-formation ; 5, a 

 portion of a striped muscle-fibre containing six parasites, one of which is in 

 the nucleus ; 6, parasite in the interior of a dilated bloodvessel fvenule) a 

 lobed parasitic mass with moniliform segments above, in the middle a chain 

 of acineta-like parasites, and below three gemmules and a larger elongated 

 parasite : a leucocyte and two red corpuscles are present : the capillary wall 

 and two nuclei complete the figure ( x 600) ; 7, an ordinary somatic mitosis 

 from the connective tissue at the margin of the tumour.
