The beautiful geometry of the cells is, after all, the marvel of the whole. Koenig demonstrated, that, in the problem of space and material, the bee had at once arrived at the solution which he himself reached only after infinitesimal calculations; and it furnishes fresh proof of the great mathematical relations of the universe, when even instinct is found to take on the accuracy and method of crystals. This honey-comb, by the way, is a favorite figure in Nature. If one examines microscopically the beautiful and brilliant petal of a gladiolus, it will offer this cellular structure in loose and irregular outlines; but under the same lens, the eye of a dragon-fly, which displays by daylight a jewel-like transparency, will be seen a strict crowd of glittering hexagons, with every alveole so closely arranged and so symmetrically shaped as to afford instant testimony to the superiority of the animal organization. It is by no means the habit of all bees, however, to dispose their affairs with such precision, though many other methods may have an equal grace. Don Felix d'Azara tells us of South American bees which deposit their honey in small waxen cups, and are known as Angelitos, because never using the sting; while the little black stingless bee of Guadaloupe, which inhabits the clefts of hollow rocks by the seaside, stores its honey in cells the size of a pigeon's egg, each sacklet being filled only so far as it will hold without tearing from its fellow, and a pretty piece of color being effected by the amber honey in its receptacles of dark violet-colored wax which never blanches, as the whole hangs together like a great cluster of grapes. This is a species of bee not greatly differing from that which makes the honey of Estabentum, that Clavigero says is taken every two months and is the finest in the world. The Mexicans are reported to attend with care to the culture of these bees, not so much for their rich honey as for the wax, of which large quantities are used in their common church ceremonials.
