 mere structural detail, and have dwelt as much 

 as possible on those more interesting features 

 in the interrelation of the plant and animal 

 worlds which have vivified for us of late years 

 the dry bones of the old technical botany. 



My principle has been to unfold my subject 

 by gradual stages, telling the reader one thing 

 at a time, and building up by degrees his know-
