plays
the important part; not the nose of the patient. In fact, most of the
famous authorities, among them Professor Jaeger of Stuttgart, Dr. Heim
of Berlin and Dr. Lahmann of Dresden, have made very valuable
discoveries in this respect.

Dr. Heim has found methods of determining the nature of certain acute
diseases from the odour emitted from the person.

Dr. Lahmann distinguishes the hypochondriacal, the melancholic and the
hysteric odours, which, as he says, are most characteristic.

The same applies to the odour of diabetics and other people who suffer
from disturbances of digestion, and patients who suffer from cancer and
other diseases involving a process of putrefaction.

The fact that most patients diffuse unpleasant odours is of the greatest
importance to married people, as it easily produces antipathy, and
especially in the case of chronic diseases, is frequently made the basis
of separation and divorce.

Were this defect known to be but the symptom of a curable disease, the
husband or wife would probably prefer to consult the hygienic physician
rather than the lawyer. Knowledge in such case would mean the
preservation of domestic happiness.

_The teeth_: The parents of a young man once complained to me that their
son had been rejected as a cadet at West Point upon physical
examination, because two of his teeth were filled.

The authorities are certainly justified in their decision.

The lack of perfect teeth indicates faulty digestion. Usually the teeth
are ruined during youth because children breathe through the mouth
instead of through the nose,--either on account of the physical
condition of the nose or because the tonsils are enlarged.

The lack of sufficient nutritive salts in the diet is often revealed by
the condition of the teeth.

From a physiological standpoint the teeth are no less important than the
brain, the eyes and the hair; and the conclusion that perfect eyes, hair
and teeth indicate a perfect brain is absolutely justified, while the
lack of perfection in these organs shows internal deficiencies long
before they appear in external manifestation in the form of disease.

Since healthy blood is the basic condition of healthy teeth, the fact
that people have clean white teeth, set in regular line, indicates the
existence of healthy blood. On the other hand, a bad composition of the
blood is manifested by short, irregularly set, yellowish teeth.

The teeth of healthy people are alwa
