had taken into its body a living one. It was entirely 

 surrounded by the Amoeba (fig. 121, a), and was 

 struggling to escape by rapidly revolving on its long 

 axis, as it could not move either backwards or 

 forwards. In a few minutes it suddenly ceased to 



C. hirtus evidently feeding on the Amoeba, and they 

 really appear to be aware that it is dangerous to 

 remain too long feeding at the expense of the Amoeba. 

 For several times I have seen the latter, while C. hirtus 

 was busy feeding on the centre or front (fig. 122, /'), 



move or exist, and evidently became the food of the I send forth on each side two powerful processes (r,

 shape and outline of it remained visible for some 

 time carried about in the Amoeba. The dark colour 

 of the C. hirtus was soon gone, evidently assimilated 

 by the Amoeba, and was rendered as translucent as

 times the C. hirtus has remained in the position at 

 fig. 122, d, until there was but just sufficient room to 

 escape by withdrawing backwards. But woe to the 

 intruder if once the processes closed around it ; and 

 this I have witnessed, which proved to me the
