Two charts are pre-sented to illustrate the life cycles of these two parasites (figs. 78, 79).It will be noticed that a certain tick, taking up both of these parasites inits nymphal stage from a given dog, would communicate the Haemogre-garina to its adult host, but the Babesia would not be transmitted u
