One of the Coceidia, C, oviforme, is very common in the liver of rabbits and has also occasionally occurred in Man. It is found encysted in the interior of nodules in the liver, and the development goes no further than encystation in the body of the host. On escaping from the body, however, each Coccidium breaks up into four spores, and the contents of each sporo later divide into two comet-like bodies (sporozoites) which, when swallowed by ix rabbit, make their way to the liver, where they encyst. 2.
