112 Marvels of Po nd-Life. 



example, the cilia are viewed at right-angles to their 

 length, they will seem to form a delicate frill, in which 

 a quivering motion is perceived. But if the table is 

 shaken by a sharp blow, the frill is thrown into waves, 

 or takes the form which washerwomen give to certain 

 female articles by the use of the Italian iron, and the 

 ciliary motion is thus made to take place in different 

 planes, and rendered strikingly apparent. 



One day turning over the Anacharis in search of 

 subjects, a small brown tube was noticed, from which 

 a glassy rod protruded like the feeler of a rotifer. 

 Keeping the table quiet, and watching the result, was 

 soon rewarded by a further protrusion of the feeler, 

 accompanied by a portion of the body of the inmate of 

 the tube. The feeler was thrust on this side and on 

 that, as if collecting information for its proprietor, who, 

 I suppose, was satisfied with the intelligence, and 

 gradually extended herself, until she stood out two 

 thirds in length beyond the tube, and set two lobes of 

 one nearly continuous ciliary organ in rapid motion. 

 Sometimes the creature, Cephalosiphon limnias, bent 

 its neck, if I may so speak, to the right, and sometimes 

 to the left, and sometimes stood upright, when the 

 true form of the ciliary apparatus could be seen. The 

 tube of this creature was opaque, from the adhesion of 

 foreign matter, and presented . an untidy appearance, 

 strangely contrasting with the clear, neat bottles of the 

 Floscules. These Cephalosiphons are very whimsical 

 in their ways, and many that were sent to different 

 observers never exhibited their ciliary wreaths, but 

 performed sundry antics, disguising their true shape.
