Abstract
The first thing which appeared when the shell was broken at its big end was the tunica which coats the entire inner surface of the shell. It serves as a common envelope for all the parts contained in the egg. It is rough externally, smooth internally, and, towards the big end of the egg, it forms a fairly large cavity. Next to this, a second tunica has a smooth external surface and closely covers the albumen. When it is broached, the albumen flows out.
