 and ad\anta^'e has been taken of this to exploit the use of ozone to an ex- 

 tent eoini)aralile almost with field mininj; or oil well jtrospeets. The f;reat 

 iminher of extravajiant elainis. which have heeii ma<le. have tended to hrin^; 

 this activated foi-ni of oxy.iren in considerable disi-epute with scientists 

 and othei's who like to be careful as to tiie truth of the statements they 

 a<-cept. The reaction has been so jireat that a .t,'ood many peijile have 

 come to thiid< that the term "(./.(MH'" and all it si.unities is merely a snare 

 and delusion. Just because bad oil stock has been sold is not a good reason 

 for believing that all oil stock is worthless; nor is it right to allow oneself 

 to be completely prejudiced by extravagaid claims of certain unscrupulous 

 IKTsons. Lot us first of all. consider the actual facts of the case. 



Ozone f/ofs seem to have a stiniuhitiiig effect if taken at the c(urect con- 

 centration. Thus, right after a thunderstorm, when the air is exhileratingly 

 fresh, ozone is present at a concentration of about one pai't in ten nuUioii. 

 This is sutticient to act on a sensitive i>hotograpluc i>late. Such a concentra- 

 ti<iu is not at all harmful hut is actually stinuilating. But tliis stimulation is 

 not one with harmful after effects, since it consists in the addition to the 

 blood of a more active modification of oxygen wliich is then \\>vd in oxidiz- 

 ing the fuel in the body, thus making available more energy foi' muscular 

 work. 



Other stimtdants like alcohol have injurious side actions which often 

 cause a great deal of harm. lint even here the claim is made and sui»ported 

 by considerable evidence tliat alc<ihol in small concentrations is i»ractically 

 iiarmless and may even be possibly beneficial. The ill effects of higldy 

 concentrated alcohol are too well known to need more than mere mention. 

 In a similar manner ozone of a concentration of more than one part in a 

 nullion becomes harmful. It begins to attack the mucuous membr.-ine with 

 very disagreeable results. Headaches .are |.roduced which are a|it to be 

 very disjigreeable. It does not bake very much ozone to make more than 

 one jiart in a million <d' air. so that the mistake that has been maile by 

 most exploiters was to use apparatus of too high a capacity. With the pio- 

 duction of too much ozone disagreeable results have followed. 



Vov olHce ventilation there are manufactured by many concerns in this 

 country and al»roa<l cabinet ozonizers which produce a lot of ozone for a 

 very small i>ower consumption. Since a large part of the i>ri<-e of the ap- 

 liaratus deitends uixm the size, the temlency has been, partly through greed 

 .111(1 partly through ignorance to make ozonizers too big. I have known of 

 a great many cases where thes»' cabinets liave been installed in baid<s and 

 ottiees where after a while they have had to be discarded because of the 

 concentration being much too gri-at. To be successfid. the aiiiouid of
