devitalized the end result is some fomi of apical infec- 

 tion that may lie dormant throughout life, or may de- 

 stroy life itself. Do not think that because your devital- 

 ized teeth have never caused you ''rheumatism" that 

 they cannot do it. Early in the war the British thought 

 the submarine was only a joke — but they learned better. 

 Have the respect for your devitalized teeth that was 

 finally accorded the submarine. The analogy is not so 

 far fetched. The sub slips in unseen and deals its blow; 

 the apices of the teeth are unseen save by the x-ray, but 

 they are as potent for harm as you can possibly imagine. 



Now, why is it that hundreds, yea, millions of devital- 

 ized teeth have (apparently) gone through life without 

 •causing harm? Write this dowm upon your mental slate 

 ''Vis Medicatrix Naturae". But for this prescription 

 the human race would have died out with the birth of 

 the first baby. (Let us see, was it "Adam Junior" or 

 "Cain?" Some of you ought to be able to tell.) 



The antitoxins, or anti-poisons, manufactured by the 

 system itself hold the virulent apical germs in check; 

 otherwise they would score a far greater batting aver- 

 age. But, at that, the triumvirate of the "Three T's" 

 (teeth, tonsils and toxaemia) cause about sixty percent 

 of the sicknesses of mankind (and womankind). 



In a New Jersey Hospital for the insane, scientific ex- 

 periments concerning the "three T's" were carried out, 

 with a conclusion that almost one half of the mentally 

 unbalanced could be restored to reason by the proper at- 

 tention to the "three T's". 



It were possibl-e to cite instance after instance, where- 

 in the sickness of the individual could be directly traced 

 to the teeth roots (apices), but it would be a great waste 

 of white paper without consequent gain in argument. 

 Those who doubt the deductions of such men as Rose- 

 now, Norvitzky, Arthur Smith, and many others, prob- 

 ably doubt the existance of the giraffe, and new varie- 

 ties of Heinz 's pickles. 



To doubt is a human privilege. An iconoclastic den- 

 tist has written a wonderfully funny pamphlet suggest-
