OBSERVATIONAL LESSON IX 93 



DIRECTIONS TO THE PUPIL 



In this lesson your attention is to be drawn to the fact that 

 although at first sight the structure of a man is absolutely different 

 from that of a horse, yet they are both formed upon the same plan. 

 What that plan is and how the man and horse differ from one 

 another in respect to it, you are to find out for yourselves.
