PURE AIR. 275 



and are very noisome and unhealthy, if shut up, 

 and kept warm. This, is very wrong, both on 

 account of the patient, and the attendants. A con- 

 stant supply of fresh air is even more necessary 

 during sickness than in health. 



Low, damp, and confined apartments are not fit 

 for dwelling places, as it is quite impossible we 

 should ever keep well in them. When deprived 

 of the cheering influences of light and cool fresh 

 air, we droop are languid depressed in spirits 

 and have no enjoyment. Our appetite is poor 

 we do not relish our food our sleep is disturbed 

 our whole frame, indeed, shows signs that it is 

 labouring under some weakening agent ; and this 

 is a damp and confined atmosphere. 



Houses, to be healthy, should be built with airy 

 rooms, and in dry situations, and not too closely 

 surrounded by trees. 



People who live in swampy districts, where vast 

 quantities of vegetable matter are constantly de- 

 caying, are subject to ague, and other troublesome 

 and dangerous disorders. This is owing to their 

 breathing damp and impure air. 



Neither man, nor animals, nor vegetables can 

 live, if the air which surrounds them be not con- 

 stantly renewed. A plant, confined in a glass case, 

 soon dies ; and instances have been known, where 

 a number of men, shut up in a small close dun- 

 geon, have perished, after dreadful sufferings.
