 together, their nature is such that the mixture is

 chemical analysis can detect a deficiency of either 

 element. We may have occasion to point out other 

 manifestations of design in the atmosphere, but for 

 the present we notice its adaptation to the wants of 

 man in the uniformity of its composition and its

 to every part, and when the air has wrought its
