The carbon (charcoal) that had been added to the blastoderm had also undergone fairly significant changes, having been spread out over a wider area of the blastoderm. The three initial points of carbon deposit were still clearly visible and provided the highest concentration of carbon in the blastoderm, but these points had more regular edges and shapes more closely approaching true circles than they had following the initial deposit of the material. Specks of carbon, including some spots of fairly sizable, extended in the same line on which the initial deposits had been placed though spread much further towards the edges of the blastoderm.
