Fig. 84. Two figures of membranes and circulation of fetal calf

(AnB, 28.)


The representation of these last two investments indicates that the sketch is intended as a diagram of the membranes surrounding a mammalian embryo, and two excellent figures on AnB, 38 (fig. 84) show that Leonardo had made a study of the pregnant uterus of a cow. In one figure he shows such a uterus with one of the ovaries and four blood-vessels supplying its walls, “these four veins a, b, c, d are tw T o of arteries and two of blood,” while the cotyledons show through indistinctly. In the second figure the fetus is shown still enclosed within the chorion, over whose surface the cotyledons, now plainly seen, are scattered and blood-vessels ramify in it, coming from the umbilical cord which is seen issuing from the ventral abdominal wall of the fetus.
