In Norwood and Rogers's process a thin coating of tin is applied to the iron before it is dipped in the zinc, by putting the plates between layers of granulated tin in a wooden tank containing a dilute solution of stannous chloride, when tin is deposited on them by galvanic action.
The separation of layers in the apical meristem of the root is usually very much more obvious than in that of the stem.
In a few cases the boundaries of the different layers are not traceable.
