The body-rings of Articulates form a skeleton, firm as in the bee and lobster, or more or less soft as in the worms. This skeleton, unlike that of Vertebrates or back-bone ani- mals, to which we belong, is outside, and thus serves to pro- tect the inner, softer parts, as well as to give them attach- ment, and to give strength and solidity to the animal. This ring-structure, so beautifully marked in our golden- banded Italians, usually makes it easy to separate, at sight, animals of this branch from the Vertebrates, with their usually bony skeleton; from the less active Molluscan branch, with their soft, sack-like bodies, familiar to us in the snail, the clam, the oyster, and the wonderful cuttle-fish—the devil-fish of Victor Hugo—with its long, clammy arms, strange ink- bag, and often prodigious size ; from the Radiate branch, with its elegant star-fish, delicate but gaudy jelly fish, and coral animals, the tiny architects of islands and even continents ; and from the lowest, simplest, Protozoan branch, which in- cludes animals so minute that we owe our very knowledge of them to the microscope, so simple that they have been regarded as the apron-strings which tie plants to animals. THE CLASS OP THE HONEY-BEE. Our subject belongs to the class Insecta, which is mainly characterized by breathing air usually through a very compli- cated system of air-tubes. These tubes (Fig. 1), which are con- FiG. A Trachea, magnifled. stantly branching, and almost infinite in number, are very peculiar in their structure. They are formed of a spiral.
