Tetrakaidecahedral

We have now space divided into equal and similar tetrakaidecahedral cells by the soap-film;

Having found, on the contrary, that the cells of elder pith are tetrakaidecahedral, and assuredly not at all rhombic dodecahedral, the problem of Juncus became one of special interest. If derived from tetrakaidecahedral cells, should they not have fourteen processes, one for each tetrakaidecahedral surface? Or is the tetrakaidecahedral form found in some tissues, as in the elder, and the rhombic dodecahedron in others, as in Juncus?

Class II / Dodecahedra sharing faces in infinite sheets, forming tetrakaidecahedral and pentakaidecahedral voids.
