 except in their tadpole state, this is not the place to 

 dilate upon the history, the anecdotes, or asso- 

 ciations connected with them. 



The small Climbing Prog of continental Europe 

 (liana arborea} might, however, form a very pretty 

 object for the island of the Aquarium, which, if only 

 as a means of cultivating semi-aquatic plants, such as 

 the Sundew and Porget-me-not, should always form 

 part of the arrangement. If such a miniature 

 island be made the abode of the Climbing Prog, a

 presented, should always be furnished. "With such
