rhombs

Each cell, as is well known, is a hexagonal prism, with the basal edges of its six sides, beveled so as to join an inverted pyramid of three rhombs.

A similar experiment may be made with small rhombs in which twin layers have been developed by mechanical force after the manner of Reusch.

And given further cleavage, by time or a sudden breaking down, even the mass, as mass, would eventually become split into smaller but perfect rhombs.

THE twisted rhombs ceased their clamour of accompaniment;

These rhombs have certain angles, and the three which form the pyramidal base of a single cell on one side of the comb enter into the composition of the bases of three adjoining cells on the opposite side.

Now we will see how calcareous spar acts upon this light—that stone which split up into rhombs, and of which you are each of you going to take a little piece home.

In ordinary combs it has appeared to me that the bees do not always succeed in working at exactly the same rate from the opposite sides; for I have noticed half-completed rhombs at the base of a just commenced cell, which were slightly concave on one side, where I suppose that the bees had excavated too quickly, and convex on the opposed side where the bees had worked less quickly.

At the other end of the series we have the cells of the hive-bee, placed in a double layer: each cell, as is well known, is an hexagonal prism, with the basal edges of its six sides bevelled so as to join an inverted pyramid, of three rhombs.

Maraldi, had measured as exactly as possible the angles of the rhombs constructed by the bees, and discovered the larger to be 109 deg 28 ', and the other 70 deg 32'.

* Reaumur suggested the following problem to the celebrated mathematician Koenig: "Of all possible hexagonal cells with pyramidal base composed of three equal and similar rhombs, to find the one whose construction would need the least material."
