and we must be careful not to anticipate the work which be- 

 longs to a higher stage of the pupil's progress. The accounts 

 of tissues, structures, and functions, add nothing to the under- 

 standing of plant-forms, and they afford proper subjects for 

 future exercises in observation, to be given in a second book. 

 What we have presented is eminently adapted to childhood, 

 when sense-impressibility, and curiosity about appearances are 

 strongest, and before the reflective powers are much developed. 

 The apparent meagreness of these pages is, therefore, inten- 

 tional. They might easily have been filled with interesting 

 reading matter about plants, but that would have opened the 

 door to lesson-learning and reciting, which is a thing we special- 

 ly wish to prevent.
