appendages or tentacles—Preliminary sketch of the action of the 
various parts, and of the manner in which insects are captured—

CHAPTER II. 
Tue MOVEMENTS oF THE TENTACLES FROM THE CONTACT oF SOLID 
Bovigs. 
Inflection of the exterior tentacles owing to the glands of the disc 
being excited by repeated touches, or by objects left in contact 
with them—Difference in the action of bodies yielding and not 
yielding soluble nitrogenous matter— Inflection of the exterior 
tentacles directly caused by objects left in contact with their glands 
—Periods of commencing inflection and of subsequent re-expansion 
Extreme minuteness of the particles causing inflection —Action 
under water—Inflection of the exterior tentacles when their glands 
are excited by repeated touches—Falling drops of water do not 
cause inflection be ps a ee a 18-31
