The greater the distention of the vessels, the more acute will be the pain: hence, the difference between a short awd protracted fast. Appetite and hunger be- long to the same class of sensations; they differ on- ly in degree. In this they are like all other sensa- tions. A little increased circulation in the vessels of lutely unpleasant feelings, and gives force and ener- gy to the mental volitions: carried further, it produ- ces most painful sensations. It is unnecessary to cite further examples. Indeed, it does not need ar- guments to prove what is the subject of every day’s observation. It is well known that the ta from acute inflammation is produced by distention of the blood vessels. Let any one, who is disposed to try
