"MONGOLIAN" DEFICIENCY
Fig . 29.—A common type of feeble-mindedness is accompanied by a face called Mongoloid, because of a certain resemblance to that of some of the Mongolian races as will be noted above. The mother at the left and the father were normal. This type seems not to be inherited, but due to some other influence,—Goddard suggests uterine exhaustion from too many frequent pregnancies.
It is, we conclude, both desirable and possible to enforce certain restrictions on marriage and parenthood. What these restrictions may be, and to whom they should be applied, is next to be considered.
