An individual will be immune so long as the carrying capacity of the nerves remain normal or so long as the carrying capacity is not decreased. Germs ingested or taken into the body will be excreted as so much waste material and will not be permitted to remain in the body. This is not only true of germs and microörganisms, but of all poisons. The carrying capacity of the nerves is limited, but in the normal condition is 100%. If the poison introduced is stronger than the internal resistance then the meeting of the two forces will produce a concussion, and if this concussion is greater than the normal resistance of the spine a subluxation will be produced. In this way an individual may be immune from one poison and not another, or from one particular germ and not another, or he may be immune at one time and not at another time. For the philosophy of subluxations being produced by poison, the student is referred to Chiropractic Library, Vol. V, Palmer, under the heading of poisons. The particular mechanism of immunity is not so vital so long as we understand that it is produced by the operation of Innate Intelligence, and know what is necessary to enable Innate to produce this condition. Under the exhaustion theory of Pasteur it was maintained that when food upon which germs fed was exhausted they could no longer develop and the body in which there was no food for the germs would be immune from the germ dis-eases. Chiropractic maintains that the germ is a scavenger and feeds upon dead tissue, never upon live tissue; that there must be a proper culture media for the development of the germs and this can obtain only in tissue that is below the normal condition. Therefore, if the tissues are maintained in a state of normality by the normal transmission and expression of mental impulses, there will be no food for the germs and they will be excreted. On the other hand, if the tissues are below normal in their resistive powers, due to the interference with the transmission of mental impulses, the germs finding food and a culture media conducive to their development will remain and multiply and their excreta will act as a poison and necessitate a further process of adaptation, the character of the symptoms depending entirely upon the character of the poison produced. It is not necessary to kill the germ that the patient may recover. All that is necessary is to adjust the subluxation or subluxations that are causing the interference with the transmission so the tissues may become normal and the germs will starve to death and be excreted as dead material. Dis-ease the Cause of Germs Dr. Alexander M. Ross, Fellow of the Royal Society of England, said in speaking of germs, “They are the result, not the cause, of dis-ease. They are scavengers; their legitimate work is to clean out the sewers of our bodies.” John B. Fraser, M.D., CM., writes, “The reasons for questioning the germ theory are mainly three, viz.:
