 both which contribute to expend the general quantity of fen- 

 forial power, which belongs to this membranous aflbciation ; 

 and thus the ftomach and inteftines aft with lefs than their 

 natural energy. This is generally efteemed a favourable fymp- 

 tom in difficult dentition, as the pain of the alveolar membranes 

 cxhaufts the fenforial power without producing convulfions for 

 its relief. See Clafs I. i. 4. 5. And the diarrhoea ceafes, as
