 thofe concerned in the circulation, in fecretion, in 

 refpiration. But the irritative fenfual motions, or 

 ideas, are not excited ; as the immediate organs of 

 fenfe are not (limulated into aclion by external ob- 

 jects, which are excluded by the external organs 

 of fenfe ^ which are not in fleep adapted to their 

 reception by the power of volition, as in our waking 

 hours. 



4. The aflbciate motions continue; but their 

 firfl: link is not excited into aclion by volition, or 

 by external ftimuli. In all refpecb, except thofe 

 above mentioned, the three lad fenforial powers are 

 fomewhat increafed in energy during the fufpenfion 

 of volition, owing to the confequeiit accumulation of 

 the fpirit of animation.
