The Turcomans belong to the great Turkish family,* of this I have not the slightest doubt; and between them and the Uzbeks I see only a difference of tribe and nothing more: the types are similar; the face is flat, large, and pointed at the chin; the beard is sandy or light, thin, and irregular; the head often too small for a body exhibiting considerable development of muscle; the face is pierced with two small holes, the form of which recalls the eyes of a Chinese.
