 may be of benefit to mankind. 



Ozone may be absorbed in large quantities by cod-liver 

 oil ; and may it not thus be of use under some circum-

 diseases to try its inhalation, and see if the inflammatory 

 action upon the mucous membranes does not mitigate 

 the prior disease ? 



Ozonized oil injected in quadrupeds increases the action 

 of the heart ; is it possible it might thus in some cases 

 avail something for man .^ It is now used extensively in 

 Boston to destroy the empyreumatic taste of whiskey. 

 Its action on diluted spirit is to bring into existence the 

 acetic fermentation with great intensity especially if any 

 sugar be present. Can we not gain hints from effects 

 thus produced by which we can make it useful.''

 covered with this frosty vapor, but, here and there, it 

 arose in columns many hundred feet high, and passed
