 tails of my unsuccessful pedigree-culture, it may 

 be as well to give some more instances of what 

 occurs in nature.

 numbers when perseveringly sought for. 

 Pitcher-like leaves may be found on many trees 

 and shrubs and herbs, but ordinarily one or 

 only two of them are seen in the course of many 

 years on the same plant, or in the same strain. 

 In some few instances they occur annually or

 Leaves may have two tips, instead of one, the 

 mid-vein being split near the apes, and the fis-
