Hutchinson speaks of a child who was perfectly edentulous as to temporary teeth, but who had the permanent teeth duly and fully erupted.

Guilford describes a man of forty-eight, who was edentulous from birth, who also totally lacked the sense of smell, and was almost without the sense of taste; the surface of his body was covered with fine hairs and he had never had visible perspiration.

This is probably the same case quoted in the foregoing paragraph in regard to the anomalies of hair.

Otto, quoted by Sedgwick, speaks of two brothers who were both totally edentulous.

It might be interesting in this connection to note that Oudet found in a fetus at term all the dental follicles in a process of suppuration, leaving no doubt that, if the fetus had been born viable, it would have been edentulous.
