willingly yielded to, and is at the same time of a cheerful kind, 

 will be always found of great service. 



Play, in which some skill is required, and where the stake is 

 not an object of much anxiety, if not too long protracted, may 

 often be admitted. 



In dyspeptics, however, gaming, liable to sudden and con- 

 siderable emotions, is dangerous ; and the long continuance of 

 it, with night-watching, is violently debilitating. But in me-

 only amusement that can engage them. 



Music, to a nice ear, is a hazardous amusement, as long at-

 first, because it withdraws a person from many objects of un- 

 easiness and care which might present themselves at home ; 

 secondly, as it engages in more constant exercise, and in a great- 

 er degree of it than is commonly taken in airings about home ;
