In Mauritius, away off yonder in the solitudes of the Indian Ocean, there is a person who answers to our Indian doctor of the old times.

He is a negro, and has had no teaching as a doctor, yet there is one disease which he is master of and can cure, and the doctors can't.

They send for him when they have a case.

It is a child's disease of a strange and deadly sort, and the negro cures it with a herb medicine which he makes, himself, from a prescription which has come down to him from his father and grandfather.

He will not let any one see it.
