pleasure, by securing a proper circulation of Blood 

 through it. 



1208. Remark. As the ganglia of the senses (SENSORITTM) are near 

 the other brainial ganglia, and in relation with them, it is not strange 

 that their activities mutually influence each other, since if activity of 

 one class of ganglia solicits Blood to itself it would easily be turned 

 from that channel to another near by. Hence, to address the senses, 

 and arouse the circulation toward their ganglia, is to advance one step 

 toward arousing the other ganglia ; and as the senses are always open 

 to attack, or solicitation, one of the best ways of reaching the inatten- 

 tive mind with instruction is often through the senses, as they, espe- 

 cially that of hearing, have a very intimate relation to the emotions, and 

 these may be easily awakened through the portals of the ear. So also, 

 through the sensatory and emotory, the intellectory ganglia are aroused. 



1209. Inf. When children are listless, let them sing some lively 

 song ; the tones heard, the air inspired, and the exercise enjoyed, will 

 quicken the Blood through all the ganglia. For this purpose, object- 

 teaching must, of course, be admirably adapted.

1210. THE CAPILLARIES, VEINS, HEARTS, ARTE- 

 KIES, and incidentally the Lymphatics, are but parts 

 of a whole, adapted to keep the Blood in rapid motion 

 through every organ of the body, and very frequently 

 expose it to the action of the air in the lungs.
