13 exhibited them in the liver ; in one case as many as 6 were found. 
In another there seemed to be none in the liver but one outside the 
intestine, in 7 cases the sporocysts occured in the liver only. In no 
case were there any worms in the foot and no sporocysts in the 
liver or round the intestine. Evidently the liver is the favourite 
place for the sporocyst.
