70 Equine Piroplasniosis 
Diagram III. N. eqiii. Illustrating the behaviour of a large parasite within a corpuscle 
during the period 17 to 176 minutes after the blood was drawn. The parasite appeared 
alternately rounded, amoeboid and piriform, and finally became rounded when all 
activity ceased. (Horse I, 6. xii. 1909. G.H. F. N. del.)

Diagram IV. N. equi. Illustrating the behaviour of a large parasite within a corpuscle 
during the period 19 to 237 minutes after the blood was drawn. The parasite 
appeared oval at first, then protruded a pseudopodium which caused it at times to 
appear piriform; then it protruded two pseudopodia so that it somewhat resembled 
a dividing form of Piroplasma. Finally, it became rounded and ceased to exhibit 
movements. (G.H.F. N. del.)
