It has been sufficiently emphasized that all phases of knowledge 

 are related and that it is impossible to study one without touch- 

 ing upon the others. Such a summary may serve both to acquaint 

 the student with the wide ramifications of the subject of botany 

 and to show the position of plant physiology in reference not only 

 to the other botanical sciences but to the general world of thought 

 as well.
