56 Russell's Familiar Notice of some of the 



surface. But when the tubes were elevated above the surface, 

 an occasional jet only was observable. 



The orifice at the tubes exhibited a beautiful structure. A 

 series of cilise (hair-like bodies) delicately fringed on both sides, 

 consisting of four larger, alternating with an equal number of 

 smaller, seemed intended for the creation of a current of water, 

 similar to that observed in the Infusoria. The same number of 

 short and obtuse points, without any fringe were inserted on the 

 margin of the tube used for rejection of improper substances, 

 the economy of which does not appear.
