1. Introductory Exkkcisks. — These consist 

 of marching : movements of legs and arms ; easy 

 trunk and head movements ; simple exercises used 

 to gain muscular control and to prepare for those 

 which follow. They (]uicken the circulation ; prepare 

 the bodv for special work : give the teacher an 

 opportunitv to correct faults of posture, and bring 

 teacher and pupils into touch with each oilier, and 

 both into the spirit of the work. 



2. Akrii Flkmons (see Figure 106) consist of 



backward bendings of the trunk in the dorsal region, 

 movements which have a special effect on the thorax; 

 thev contract the muscles of the back, straighten 

 the dorsal spine, elevate the chest and correct its 

 posture. The chest capacity is enlarged, and respir- 

 ation increased b\- reaction. The immediate effect 

 is to draw more air into the lungs and. therefore, to 

 supply more oxygen to the muscles. This is abso- 

 lutely necessary as a preparation for more diiticult 

 nu)\-ements whirb fiillow— tor without this increase 

 of ox\gen tlie\- eitliir could not be well done or 

 might cause strain. There is permanent enlarge-

 contained in the tiiorax and alnlomen. This jiroduces
