XIX Observations on Egg and Chick

Chapter

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.
