origin, till recently, the old conceptions respecting many affections, 

 such as heart disease, still prevailed. 



The war revealed young men with all the symptoms and signs of 

 heart disease, kidney disease, etc., but the fibrous change was absent. 

 The majority of these men recovered, though suffering from what 

 we had hitherto called 'incurable' diseases. 



Dysentery, trench fever, scarlet fever and other 

 of much Disease diseases were found to be followed by heart and other 



organic troubles, which showed that these diseases 

 were due to the invasion of the body by germs. It became evident, 

 therefore, that the so-called fibrous changes, are, in reality, signs of 

 Nature's struggles against disease. 



The new medicine does not shake its head over heart murmurs; 

 it seeks the infection, whether in the teeth or throat or alimentary 

 tract or elsewhere, and attempts to eradicate it. "The shining 

 truth, that, if we can prevent or stay infection, we can probably 

 prevent all the effects of infection — that is to say, the bulk of 

 disease — has not yet been seen by all. When it is seen, it will no 

 longer be necessary to conduct an Al Empire on a C3 population."* 



Chronic Disease The new medicine has demonstrated that the public 

 Due to Teeth should concentrate their attention on one disease 

 almost above all others, namely, decay of the teeth. This disease 

 lowers the health of the child and predisposes it to tuberculosis 

 and disease generally. It is estimated that at least 20 per cent of 

 all chronic disease in Great Britain is due to the teeth. 



The president of the Dental Association of New Zealand, in urging 

 the establishment of dental bursaries, stated that 95 per cent of the 

 school children of New Zealand had dental caries. He said that, if 

 cows were similarly affected, they would not be tolerated for one 

 month. 



Dr. Sim Wallace, the dental surgeon, states that the chief cause 

 of dental disease is the "adhesive and easily fermentable nature of 

 the modern diet; also meals between meals, and especially the bread- 

 and-milk at bed-time. The last named leaves a poultice over the 

 crevices of, and between, the teeth during the night;" nascent lactic 

 acid forms, attacks the enamel and starts the disease.
