CHAPTEK I. 



DROSERA ROTUNDIFOLIA, OR THE COMMON SUN-DEW. 



Number of insects captured Description of the leaves and 

 their appendages or tentacles Preliminary sketch of the 

 action of the various parts, and of the manner in which 

 insects are captured Duration of the inflection of the 

 tentacles Nature of the secretion Manner in which 

 insects are carried to the centre of the leaf Evidence that 

 the glands have the power of absorption Small size of 

 the roots Pages 1-18 



CHAPTER II. 



THK MOVEMENTS OF THE TENTACLES FROM THE CONTACT OF 



SOLID BODIES. 



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 yield- 

 ing 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 19-37
