antennæ are said to have also another office, viz., that they act as a barometer, by which bees know the state of the weather and are premonished of storms; so that this pair of horns play an important part, since such useful faculties are thus combined. In the dark recesses of the hive the antennas are exceedingly serviceable, and may truly be denominated "eyes to the blind." Bees possess acutely the senses of taste and smell. In consequence of their being detected occasionally lapping the impure liquids from stable or other fœtid drains, Huber considered the former the least perfect of their senses. It is now ascertained that bees, like most animals, are fond of salt; and in spring, more especially, their instinct teaches them that salt is beneficial for their health after their winter confinement, and they therefore resort to dunghills and Stagnant marshes, from which they are, doubtless, able to extract saline draughts. It cannot be denied, however, that, according to our ideas, bees' taste is otherwise at fault; it sometimes happens that, where onions and leeks abound and are allowed to run to seed, bees are so anxious to complete their winter stores, that, from feeding on these plants, a disagreeable flavour is communicated to the honey. Again, the fact, well known in history, related by Xenophon in the retreat of the Ten Thousand, that bees in Asia Minor extracted honey from plants which had not only a disagreeable but a poisonous tendency to man, shows that it is quite possible, where such poisonous plants abound, for the bees to extract the juices without any injury to themselves. The sense of smell, so largely possessed by bees, is extremely serviceable to them. Attracted by the fragrance of flowers, bees may be seen winging their way a considerable distance in an undeviating course, even sometimes in the face of weather which one might have thought they would not have braved. The thorax or chest approaches in figure to a sphere, and is united to the head by a thread-like ligament. This is the centre of the organs of motion. Here are attached both the muscles that move the legs and wings, and the legs and wings themselves. In Plate II., fig. 1, _b, b, b_, show the muscles that move the wings; _e, e_, the bases of the wings. The wings consist of two pairs of unequal size, which are hooked to one another. In Plate I., fig. A, will be seen the margins of the two wings. In fig. B are the eighteen or twenty hooks placed on the anterior margin of the hinder wing, whilst the posterior margin of the fore wing is beautifully folded over to receive them, so that, when distended for flying, the two wings on each side act as one to steady their movements in flight.
