this state of affairs, such as rheumatism, sick-headache, biliousness, etc., are likely to develop. The centers of the special senses feeling the lessening of the vital fluid, such troubles as impaired vision, impaired hearing, loss of appetite (sense of taste) and inability to detect odors quickly soon follow. The sense of touch becomes more acute, and it is for this reason that one in poor health becomes hypersensitive. Lowered circulation in the mucous membrane of the throat and nose is often the cause of nasal catarrh appearing on the scene as an early symptom." It will thus be seen that the Physical Conditions, perhaps originally caused by depressing Mental States, have brought about a state of affairs in which the brain is imperfectly nourished and which consequently cannot think properly. The liver being out of order, the spirits are depressed; the brain being imperfectly nourished, the attention and will are weakened, and the patient finds it hard to use his mind to influence his bodily conditions. The bowels not moving properly, the waste-products poison the circulation, and the brain is unable to think clearly. In fact, the whole physical system is often so disturbed that a condition known as "nervous prostration" sets in, in which it is practically impossible for the patient to hold the Mental States which will improve the Physical Conditions. In these cases outside help is generally necessary, unless in cases where a sudden shock, or an urgent necessity arouses the latent mental forces of the individual, and he asserts the power that is in him, and begins to reverse the chain of cause and effect and to start on the upward climb. The following additional quotation from Dr. Parkyn, gives us a vivid insight into the effect upon the Mental States of abnormal Physical Conditions: Dr. Parkyn says: "No organ of the body can perform its functions properly when the amount of blood supplied to it is insufficient, and we find, when the blood supply to the brain is not up to the normal standard, that brain functions are interfered with to a degree corresponding to the reduction in the circulation. Since the amount of blood normally supplied to the brain is lessened in nervous prostration, we find that the memory fails and the ability to concentrate the attention disappears. The reasoning power becomes weakened and the steadiest mind commences to vacillate. Fears and hallucinations of every description may fill the mind of a patient at this stage, and every impression he receives is likely to be greatly distorted or misconstrued. Melancholia with a constant fear of impending danger is often present. In fact, the brain seems to lose even the power to control its functions, and the mind becomes active day and night.... The reduction of the nutrition to the brain lessens the activity of all the cerebral centers also, and digestion becomes markedly impaired, thereby weakening the organ itself upon which the supply of vital force depends."
