How horrible! exclaimed McCall.

Professor, we must--

Yes, pretty bad, commented Professor Brierly,

Not from Tommy's mouth?

No, Mrs. Van Orden, you may be certain of that. The roots of a child's teeth undergo a certain amount of disintegration before it is ready to give place to the permanent teeth. We will not go into the mechanical and biological reasons for this destruction; it is not important. While this is a deciduous tooth, I mean a baby tooth, it is not Thomas's tooth. How old is Thomas, Mrs. Van Orden?

He was just four and half years old yesterday.

Exactly, I thought so. No baby's tooth at that age shows the amount of disintegration that this tooth shows. Depend on it Mrs. Van Orden, this tooth comes from the mouth of a child of not less than nine years of age.

You are certain of what you say, Professor, that this is not Tommy's tooth.
human
Depend on it, sis, interrupted Matthews.

Professor Brierly could not be mistaken in a thing like that. What I want to know is why--why this?
