each leaf is attached a small tube, shaped like 

 a pitcher, or horn, covered with a lid, which 

 is moveable on a kind of hinge or strong fibre, 

 passing over the handle, and connected with 

 the leaf. By the contraction of this fibre the 

 lid is opened, when the weather is showery or 

 the dews fall ; and, when the moisture has 

 filled the pitcher, closes again so firmly as to 

 prevent evaporation, securing the water for the 

 sustenance of the plant or thirsty travellers. 



EDUCATION OF FISHES. 



Fishes have been seen to possess, in a greater 

 or less degree of perfection, all those external 

 senses by which other animals acquire a know- 

 ledge of external objects. Hence we find 

 that they speedily become acquainted with the 

 hand that feeds them, and know the face of a N 

 stranger. They may be taught to come to the edge 

 of a pond, when called by their usual name, 

 or to assemble at the sound of a bell. Raster 

 even informs us of a trout which had been 

 kept fourteen years and seven months, which 

 would come and repose on the hand of its mas- 

 ter, while he removed the water out of the 

 vessel in which it was kept.
