Abstract
THE following experiments were undertaken on dogs, rats and rabbits to determine whether or not it was possible to reproduce in animals some of the many striking phenomena that have been observed in the human fetus of the diabetic mother. It is well established that the fetal and neonatal mortality is increased among infants born to diabetic mothers and that there is a marked tendency for the human fetus to have an increased birth weight without evidence of a prolonged gestation period. Changes in the viscera and endocrine glands of some infants born to diabetic mothers have also been reported.
