size of the original, 

 the cirrhose wire (fig. l 

 c.) is elastic, and suffi- 

 ciently firm to sup- 

 port the pitcher, when 

 full of water, in an 

 upright position. It 

 gradually enlarges as 

 it approaches the 

 pitcher, becoming in- 

 flated on the upper 

 surface (</.), but re- 

 maining flat and firm 



on the lower; the angles of which gradually ter- 

 minate in two costae (e. e.), that run up the 

 fore part of the pitcher, and give out branches 

 which pass obliquely across the pitcher, and ter- 

 minate in the vessels supplying the lid (a.). The 

 structure of the cirrhose support is the same as 

 that of the petiole ; the proper or returning vessels 

 are very numerous, the spirals are large, and 

 constructed of four flattened threads. The pitcher 

 exactly resembles the leaf in its structure, the 

 whole of the vascular fascicles being prolonga- 

 tions of the petiolar bundles, or branches from the 

 two costae already described. The coalescence of 

 the fascicles at the back of the pitcher, near the 

 ring of the mouth, forms a third large costa, 

 which is, as it were, inverted, and branches down-
