iV. equi multiplies slowly and in the following manner: 
(1) The minute piriform or oat-shaped parasite enters a fresh 
corpuscle and (Diagram VI, 2, 3, 4, 5) grows in size, being slightly 
amoeboid, with a general tendency to resume a pear-shape. Definitely 
amoeboid movements (6) are, however, only to be seen distinctly when 
the parasite has attained a certain size. Judging from the form of 
the chromatin masses, stages 7, 8, 9, 10 follow next. The rest of 
the cycle has been continuously observed in the living parasite : the 
formation and breaking-up of the cross-form, the scattering of the 
daughter cells within the corpuscle, and their escape from the corpuscle.
