Exercise, off 



the effects of a completely inactive statc^ amongsft the most inUolenf, 

 and most incorrij^ible mendicants of this country, who herd together 

 in filthy apartments, like mere animals, their squalid countenances, 

 and generally diseased frames, are at once both loathsome to tht 

 senses, and afflicting to humanity. Again, if we investigate the 

 case of those mechanics who follow sedentary employments and are 

 crowded together in ill-v«ntilated places ; their languid eyes, and pa- 

 lid complexions, prove to us, that they do little more than merely 

 exist. Such, however, as labour hard, and, who, from the nature 

 of their employment, bring all their muscles into play, though under 

 the same disadvantage of breathing a vitiated atmosphere, do, 

 nevertheless, rise considerably higher, in the scale of health and vi- 

 gour, than the former ; but, in vain shall we look, even amongst the 

 latter description of persons, for the ruddy cheeks, and wiry sinews 

 of the ploughman. 



And if any farther proof were needed, of the astonishingly bene- 

 ficial effects of pure air on Horses, it is only necessary to recollect 

 various instances in which, many, that where supposed to be dy- 

 ing, have been turned out of hot stables, to grass, (merely upon 

 the principle of the forlorn hope,) and have, nevertheless, been 

 known to struggle through the disorder. For, though something, no 

 doubt, must in these cases, be put down to the restoiative effects of 

 the grass upon the system, at a time when the powers of the stomach 

 were, perhaps, not adequate to the digestion of any other kind of food, 

 yet, certainly, much more ought to be attributed, to the salutary action 

 of the external air, for which, thousands and tens of thousands 

 of stoved Horses, languish and pant, even as the hart pantelh for 

 the water springs.
