REBREATHED AIR. 35 



the rural districts. The winds whistled through 

 the dwellings then, and the fire blazed and roared 

 upon the hearth. Half the time, in the cold win- 

 ters, " the backs of the inmates were freezing, while 

 the front parts of the person were roasting ; " and 

 yet there was less rheumatism than now, and no 

 consumption. 



Whilst we have made changes in dwellings, 

 workshops, and public buildings, which operate to 

 sadly deteriorate and confine the interior air, the 

 outside atmosphere is just as pure, just as healthful, 

 as in the days of our ancestors. Let us adopt 

 means to secure a full measure of this " pabulum 

 of life," clear, undiluted, uncontaminated, day and 

 night, during the hours of sleep and study. Let 

 us live as much as we possibly can in the open air, 

 and the measure of health will be greatly increased, 

 and life prolonged.
