Fig. 481. Dorsal view of embryo of albatross, showing amnion covering greater part of embryo

Schauinsland.

The amniotic cavity is filled with fluid, the liquor amnii, the origin of which is uncertain. In it the embryo floats freely, attached only by its ventral connection with the yolk. At about the fifth day of incubation rhythmical contractions of the amnion begin. These are apparently due to the development of contractile fibers in its mesodermic tissue and give to the embryo a regular oscillating motion.
