Seite 131 - To trace in Nature's most minute design, The signature and stamp of power divine, Contrivance intricate expressed with ease, Where unassisted sight no beauty sees, The shapely limb and lubricated joint, Within the small dimensions of a point, Muscle and nerve miraculously spun, His mighty work who speaks and it is done, The invisible in things scarce seen revealed, To whom an atom is an ample field.

The head, thorax, and abdomen, differ almost entirely from the same parts in the labourers and soldiers; and, besides this, the animal is now furnished with four fine large brownish transparent wings, with which it is at the time of emigration to wing its way in search of a new settlement.
Seite 27 - ... ripe, after which time the slightest application of warmth and moisture is sufficient to bring forth, in an instant, the latent larva. At this time, if the tongue of the horse touches the egg, its operculum is thrown open, and a small active worm is produced, which readily adheres to the moist surface of the tongue, and is from thence conveyed with the food to the stomach.
Seite 58 - Africa, that it is scarcely possible to stand upon any open place, such as a rice- plantation or other clear spot, where one or more of these buildings is not to be seen within fifty paces. In some parts near Senegal, as mentioned by Adanson, their number, magnitude, and closeness of situation, make them appear like the villages of the natives.
Seite 18 - ... they viewed with a curious eye the common dress of the Chinese, the manufactures of silk, and the myriads of silkworms, whose education (either on trees or in houses) had once been considered as the labour of queens.
Seite 54 - The burying-beetles hunt in couples, male and female ; and when six or eight are found in a large animal, they are almost sure to be males and females, in equal numbers : they hunt by scent only, the chase being mostly performed when no other sense would be very available, viz., in the night.
