We might tolerate the profession's syphilomania if it were not so pessimistic and fatalistic. But from years of experience we know that nature can throw off every disease that has not become organic; all that is necessary in the line of treatment is to remove every influence that is obstructive to the body's functioning. We know that the body is busy throwing out toxins, and if there is an accumulation--if elimination is not equal to accumulation--all that is necessary is rest (physiological rest), and nature quickly returns to the normal. There is no stimulation to elimination that equals physiological, physical, and mental rest.

That drugs will bring about elimination is true; but they bring a disappointing relief, for they excite to action and leave the organs more enervated. As a consequence, a relapse follows--or an apparent relapse; for, as a matter of fact, such relief is disease-building.

Hereditary tuberculosis and hereditary syphilis are analogous when found in a syphilitic or scrofulous diathesis--in a scrofulous subject coming from a father and mother of tubercular diathesis; but when one parent is scrofulous and the other gouty, the heredity is a modified scrofula or syphilis.

There is no hereditary tuberculosis. As stated before, diathesis means a tendency to develop given symptoms of diseases. Disease per se cannot cross the line drawn by sterility. To make an exact statement, diathesis means that health will deviate in a definite manner.

A child with the tuberculous diathesis well established may develop utero-tuberculous derangements.

Pronounced unmixed types of diathesis are hard to find. The tuberculous and gouty stand out more plainly and are recognized by the unskilled. A pronounced diathesis predetermines the type of diseases to which the subject is heir. The advantage of knowing to what class a child belongs, is that mistakes in climate, food, clothing, and occupation may not be made.

The tubercular diathesis should live out-of-doors, and be fed fruits and vegetables--very little animal food. The gouty diathesis develops gout, eczema, neuralgias, neurasthenia, etc. Animal food, with fruit and raw vegetables, should be the diet.

Both diatheses need grain during the developing period.

Arthritism, or gouty diathesis, presents the following characteristics: gout, eczema, nervous derangements, such as neuralgia, hemicrania, hypochondria, neurasthenia, gas, diabetes, gravel, stone in the liver, kidneys, and bladder. When the father has gout, the son has asthma, and the daughter develops arthritis deformans. A child of this diathesis has headache at puberty, and may develop asthma or rheumatism; at about middle life, gout develops, and he dies of apoplexy.

It is said that gifted people--geniuses--are of a gouty diathesis, and are very inclined to develop single faculties to their own destruction.

The scrofulous diathesis starts with catarrh; nose, throat, and ear diseases; tubercular joint and bone diseases; catarrhal inflammations of all mucous membranes; glandular diseases.

Congenital malformations are said to start from infections. No doubt the nervous systems of the mothers have much to do with fetal development.

Fetal development is a large and interesting subject, but not necessary to this book. The readers who are interested should go to their public libraries, where they will find textbooks on the subject.

Physiological heredity is the innate power of the cell to reproduce a successor.

Ribot declares it to be a biological law that enables living beings to repeat themselves in their offspring.

There are two laws, however: first, the law of conservation--retaining ancestral type; and, second, that of evolution.

Conservation is the greater. Indeed, when we see with what tenacity humanity clings to all beliefs and customs, we sometimes wish that nature would relax her vigilance. But when we see how necessary it is for great resistance to be present all the time to prevent disease--degeneration--from crossing the lines drawn by heredity or transmission, we are made to rejoice that degeneration cannot be transmitted.

There is a temptation to write on the subject of reproduction and other features of heredity, but space will not permit. Darwin, Ribot, Haeckel, Weissmann, and many others will furnish the reader material out of which he may formulate his own belief.
