In these two things, the protoplasm and the nucleus, we have become acquainted with the essential constituents of the cell. The youthful cell shows nothing further. Later, it may become different. The surface of the cell body hardens, or from this vicinity is formed a firmer envel- oping layer. Thus we have, when this remains very thin, what is called a cell membrane, while to a thicker covering is given the name of the cell capsule. We just said, " this may occur ; " but it need not.
