Fig 6. Table 1 illustration from Wolff's "On the Formation of the Intestine"

1 . Vascular area (area vasculosa) from upper surface after three days of incubation; a — vascular area; b — transparent place (area pelludica) ; c — embryo; d — heart; e — lateral yolk veins; f — descending vein; k — boundary vein.

2. Lower surface of the vascular area and on it the vesicle or false amnion; a — lower surface of the vascular area; b — transparent place; c — false amnion and on it (from c to d) cephalic branch; di — middle part of it; i to b — caudal membrane; d — cardiac fossa, from d to i, commissure; i — lower fossa; e — lateral veins; f — descending vein; g — ascending vein; h — boundary vein.

3. Upper surface of the vascular area in living embryo of three and a half days of incubation; a — embryo; b — fossa, which it forms in yolk; c — origin of yolk veins; d — their lower branches; f — middle branches; g — branching of the upper branches; h — ascending vein; k — its branches; i — descending vein; 1 — terminal vein.

4. Vascular area in living condition; a — chamber of heart; from above, bulb of aorta, from downwards, auricle of the heart; b — aorta; c — hollow vein; d — ascending vein; e — descending vein.

5. Transparent place in the embryo from lower surface, under microscope, 54 hours of incubation; a — transparent place; b — cephalic branch; c — part of the embryo above the cardiac fossa; d — anterior part of the head;

e — heart; f — first rudiment of the true amnion; g — ascending vein; h — origin of cephalic branch; i — swollen edge of the ventricle opening; k — opening of the stomach still is not closed, but has narrowed; 1 — abdominal folds; m — intestinal folds; n — rudiments of vertebrae; o — end of vertebrae; p — the beginning of formation of amnion opening; q — spinal cord; r — marked lateral parts of the vesicle; s — traces of retiform, derived from red blood, vessels; v— -first rudiment of the caudal membrane.

6. Part of lower surface of the vascular area with the transparent place and embryo, after two days of incubation.

a - the transparent place; b — cephalic branch; c — upper, swollen region of the lateral part of the vesicle; d — lower, still not swollen part; e — part of the embryo over the cardiac fossa; f — heart; g — occiput; h — anterior part of the head; i — edge of the cardiac fossa; k — left abdominal fold; 1 — right lower abdominal fold; m — internal intestinal fold; n — right intestinal fold; o— spinal cord; p— cavity of the intestinal canal; q, r — lateral deepenings, rudiments of cavity of the body; from s to t — rudiment of caudal membrane; s — united abdominal folds; t— union of the intestinal folds, origin of rectum; u — slightly bending end of the spinal chord; w— ascending vein; x — its branches; y— right lateral vein; z — left lateral vein.

7. Part of the vascular area, containing the embryo, covered by the false amnion, after 60 hours of incubation, a — immovable false amnion; b — cephalic branch; c — lateral parts of the vesicle; d — caudal membrane; e, f, i, g — embryo, translucent through the vesicle; f — occiput; g — protuberance of right leg; h — rudiment of tailbone; i — protuberance of left wing; k — cardiac fossa; 1 — commissure; m — lower fossa; n — fold of commissure; o — opening between abdominal and intestinal folds; p— fold of lower fossa; q — ascending vein; r — its branches; s— - vein associated with the ascending; t — its branches; u — descending vein; x — abdominal fold; y — area formed by the union of trunk folds.
