Since it ispostulated that everypoint in the space issubject to the domin- Fin. 1. ating influence of some next neighbouring atomic centre, it follows that the cellsfit together so as to occupy the whole available space with-out interstices. Nothingis here said about the shape ofthe cells; but since, in the case of an elementary sub-stance, the atomic, centres are all alike, so too will bethe cells. Before proceeding to discuss the actual shapesof the cells referred to, it will be convenient to illustrate.
