78 GENERAL ANALYSIS 



234. Inf. ALL PARTS OF THE BODY CRAVE exercise, 

 especially if they are in the habit of being exercised, 

 and this demand, with the succeeding one for relaxation, 

 may well be called an appetite, since they must be treat- 

 ed like an appetite, the pleasant and unpleasant effects 

 being the same.^ 



235. DIFFERENT PARTS OF THE BODY ARE COMPOSED 

 of different substances, and demand different kinds of 

 food ; and as the appetites have their seat or exciting 

 cause in the part that needs the food, the appetites for 

 food ought to differ, or crave different kinds of food. 



236. Inf. THERE OUGHT TO BE a muscular appetite, 

 a nervous appetite, an osseous appetite, an appetite for 

 calorific food, for food for the secretions, &c. 



237. Him. IF A BONE BE BROKEN, very much food 

 and of peculiar kinds should be craved ; often it is thought 

 because the man is not using his muscles, he is not doing 

 much ; he is he is growing new bone, and will digest 

 much food. 



238. STUDENTS DO NOT ALWAYS LEARN TO DISTIN- 

 GUISH a nervous appetite, entirely unlike a muscular or 

 calorific one to which they have been accustomed, and 

 more like a feeling of exhaustion or irritability, that ex- 

 perience soon teaches can be overcome by eating the 

 right kind of food. 



239. TEACHERS DO NOT ALWAYS distinguish, in the 

 lassitude, uneasiness, and discomfort of their pupils, 

 or even of themselves, the indications of an appetite for 

 air. 



240. Inf. It is certainly very unfortunate for per- 

 sons in so important relations as teachers and students, 

 not to know what is the matter with themselves, nor 

 what to do to Improve their condition ! 



241. THE APPETITES ARE RELATED to sensations of 

 Satisfaction, Satiety r Repose, Ennui, Exhilaration, Fa- 

 tigue, Rest, Exhaustion, and Quiet ; all of which may be 

 produced through the same apparatus as appetites.
