3 o INCITANTXA. Art. II. 2. &. u 



links under either the prefent hardfhips, Of by a premature old 

 age. The fecond mode of exercife is Ktn in the play of all 

 young animals, as kittens, and puppies, and children ; and is fo 

 neceiiary to their healtk as well as to tiieir pleafure, that thofe 

 children, which are too much confined from it, not only become 

 pale-faced and bloated, with tumid bellies, and confequent 

 worms, but are liable to get habits of unnatural actions, as 

 twitching of their limbs, or feme parts of their countenance ; 

 together with an ill-humoured or difcontented mind. 



Agitation in a carriage or on horfeback, as it requires fome 

 little voluntary exertion to preferve the body perpendicular, but 

 much lefs voluntary exertion than in walking, feems the bell: 

 adapted to invalids ; who by thefe means obtain exercife prin- 

 cipally by the ftrength of the horfe, and do not therefore too 

 much exhauft their own fenibrial power. The ufe of friction 

 with a bruQi or hand, for half an hour or longer morning and 

 evening, is ft ill better adapted to thofe, who are reduced to ex- 

 treme debility ; and none of their own fenforial power is thus 

 expended, and affords fomewhat like the warm-bam activity 

 without 'felf-exertion, and is ufed as a luxury after warm bathing 

 in many parts of Afia. 



Another kind of exercife is that of fwinging, which requires 

 fome exertion to keep the body perpendicular, or pointing to- 

 wards the centre of the fwing, but is at the fame time attended 

 with a degree of vertigo ; and is defcribed in Clafs II. 1. 6. 7. 

 IV. 2. 1. 10. Sup. I. 3. and 15. 



The neceflity of much exercife has perhaps been more infilled 

 upon by phyfician?, than nature feems to demand. Few ani- 

 mals exercife themfelves fo as to induce viiible fweat, unlefs urg- 

 ed to it by mankind, or by fear, or hunger. And numbers of 

 people in our market towns, 'of ladies particularly, with fmall 

 fortunes, live to old age in health, without any kind of exercife 

 of bodv, or much activitv of mind. 



In fummer weak people cannot continue too long in;the air, if 

 it can be done without fatigue ; and in winter they fhould go 

 out feveral times in a day for a few minutes, ufing the cold air 

 like a cold-bath, to invigorate and render them more hardy.
