These are by no means all the shapes, nor the 

 precise shapes that stems assume, but their forms will 

 most commonly be found to approach very nearly to 

 some of these outlines. If any forms occur that are 

 so widely different from the pictures as to perplex 

 the pupil, he will consult the teacher.
