Each cell therefore is in shape a hexagon, that is to say, a figure with six equal sides, to each of which six other hexagons attach, for each wall forms also one wall of another hexagon. The basis of each hexagonal cavity is of an obtuse three-sided pyramidal shape inverted, and consisting of three rhomboidal plates, each forming one-third of the basis of the three opposite cells; thus the edges of these three basal plates of one side support three lateral walls of three hexagons on the other side. The inverted triangular pyramid thus made by these three equal rhomboidal plates, form, at one extremity and at each pair of their posterior edges a re-entering angle, and at the other extremity a salient angle. From these edges spring the lateral walls of the hexagonal cell, this shape being superinduced by the form of the edges of the basal cavity. That the bees should have been thus guided to elect a form which combines conjunctively the advantages of strength and capacity evidently proves that it is their instinct which guides them, which, being an afflation from the highest source, ensures the most complete perfection in its result. That it cannot be the effect of simultaneous lateral pressure is proved incontestably by the whole superstructure resulting from the design of the base; and this is further corroborated by the base of one cell on one side forming invariably equal portions of the base of three cells on the opposite side,—all clearly the result of preconceived design impressed upon their sensorium. From this combination of forms results the security procured to the fragile tenement, which consists of the very smallest quantity of material that will cohere substantially, for the bees are exceedingly parsimonious of their wax, as if the production of it were attended with pain or inconvenience, and it is only upon the construction of the royal cells that a profusion of this choice material is squandered. As soon as these cohorts of bees are in active operation, it is astonishing with what pertinacity and rapidity they labour, for within the space of four-and-twenty hours they will construct a cake a foot deep and six inches wide, containing within its double area some four thousand cells. Other cakes parallel to each side of the original are being at the same time carried forward with an interval between each sufficient for two bees to pass each other _dos à dos_, and further to promote the convenience of traffic within the hive, and ready communication to its several parts, passages are left through these cakes from one to the other, so that the means of transit are opened, which of course saves much time. The queen is already making her progresses from one side of each comb to the other, and depositing her eggs as rapidly as she can, and is constantly attended by her _aides-de-camp_, as I have suggested, which act, as they evidently sometimes are, as the emissaries of her commands.
