If unconsciousness is preceded by spasm, the cause may be kidney disease--uremic coma. Symptoms may be headache, and flushed face with veins standing out. This means congestion of the brain.

A diagnosis--a decision as to the character of a disease and its cause--requires a close examination into the social life of the patient; the family history; the history of previous disease, and the diseases of the family as far back as possible; the history of the present disease; the history of family habits as well as the habits of the patient. It is necessary to know all about the personal habits of the patient, secret as well as open. The eating habits must be known--even to knowing exactly what is eaten at each meal daily. The sex life must be known--the early abuses, as well as those coming later in life.

A diagnosis, so far as determining that a certain organ is affected--for example, that the kidneys are diseased, that the patient has diabetes or Bright's disease--is far from conveying to the physician's mind an idea as to the true cause of the disease. It is true that the physician sees in his mind's eye hepatic insufficiency, or a failure in the dehydration of glucose in the walls of the intestines. But as to what has caused the malnutrition, in what way the patient has brought on his enervation, and what are his habits, the physician knows nothing from the test-tube, which only tells him that there is sugar or albumin in the urine. The diagnosis, so far as naming the diseases is concerned, may be correct; but no information is conveyed to the mind of the physician as to the primary cause of these diseases. Even when germs or parasites are given as cause, this manner of diagnosis throws no light on the question of why germs and parasites do not cause disease in all whom they infest.

Analysis of symptoms, examination of all secretions and excretions, and palpation and auscultation of all organs, amount to a scientific examination of effects; but a positive diagnosis throws no light on cause. Causes must be found and associated with effects before a curing knowledge can be possessed.

Diagnosis may be very correct, so far as effects are concerned; but cause of effects must be known.

It is necessary to know a healthy man. What are the signs of health?

The eye and the skin are clear. The outlines are normal. Those whose lines are obscured by fat are not healthy. Women who weigh over two pounds to the inch in stature are too heavy. Men who weigh more than two and a half pounds to the inch of stature are too heavy and are diseased.

Women and men who weigh much less or much more than the standards named are diseased. By diseased I mean that they give down early; they have not the resistance they should have; they age rapidly; and come to a premature grave.

A healthy body will desire only normal, natural, and simple foods.

Normal health is rare indeed. This being true, is it so very strange that so few live to one hundred or one hundred and twenty years of age-the normal lifetime of a human being?
