Plate 2.

Fig. 9

In Fig 9 and 9a shown embryo 16. 20. 96 has become fixed in Chrome acetic acid. The  ?? begin to form, but the head of still rather upright and the forehead touches not the heart. The heart is abgeholien the yolk sac. The caudal end of the embryo is wrapped all the way to the right of the embryo, to which so the allantois comes to rest. The neural tube is still open both in the area of the front than in the caudal region neuropore one on each o-Num small spot. Even at 10-times magnification, you can see how the top is indicated jaw process.

Fig. 10

The embryo is. 20, 96 c is slightly more advanced than the previous one, he is hardened in Chrome acetic acid. The controversy, which stands out at first glance, is caused by the fact that the caudal end is beaten even more vigorously to the right side and the Allantois has not grown insignificantly. Even the hint of pine About the extension is a little clearer. The neural tube is completely closed front, open back still in the region of 2 sections. In Fig. 10 b the Ohrgrübchen emerges beautifully.
