SEA-BREEZES, MOUNTAIN AIR, AND OZONE 257 



a gas may present mechanical advantages over any liquid 

 application. 



Ozone is not, apparently, in favour or fashion with the 

 general body of medical practitioners at the present day 

 but possibly further examination and determination of its 

 physiological properties may lead to its receiving more 

 attention in medicine. Already the peroxide of hydrogen 

 which is more or less correctly described as " ozonised 

 water," and is used (under the name " Auricomous hair- 

 wash ") to change dark hair by its oxydising action to a 

 golden tint is used by surgeons for washing out purulent 

 wounds and abscess. Those who use the gas itself only 

 go a step further. Some day we may see a more general 

 use of ozone ; on the other hand, it remains to be seen by 

 direct and accurate experiment whether its properties are 

 as valuable to man as we may hope they will prove to be.
