by naturalists as a hollow tube, but we now know, by dissection, that this is not the case, but that it acts as a brush, and, by a peculiar muscular contraction externally, draws the liquid into the mouth. Thus, when a bee is imbibing food, the rings of the abdomen have a vibratory motion similar to pumping, showing to the casual observer that suction is rapidly going on in some form or other. The labial palpi (Plate II., fig. 3 _o_) rise from the base of each side of this lapping instrument, and are also ciliated exteriorly; outside these are the lower jaws, or maxillæ (Plate II., fig. 2 _n_), similarly provided with hairs. When the jaws (Plate II., fig. 3 _n_ and _o_) close on the tongue, they form a sheath or defence thereto. With the mandibles of the upper jaw opening right and left, and the maxillæ or lower jaws, which serve to hold the object laboured upon, the insect prepares its work for the sweeping-up apparatus of the lower parts. Thus, when combs become mouldy, or in any way unfit receptacles for brood or honey, these tools provided by Nature serve the place of hands, and the bees are able to chop up in small pieces, and remove from their dwelling, whatever lumber of this kind may be offensive to them. The whole of this apparatus, while perfect in action in an expanded state, can be folded or coiled together when not in use, so as to form one strong and well-protected instrument. The antennæ (Plate I., figs. 1_a_, 2_a_, 3_a_,) are most important instruments, and are planted between or below the eyes and a little below the ocelli, one on either side: they consist of a number of tubular joints, each having a separate motion; being thus jointed throughout their whole length, they are, therefore, capable of every variety of flexure, and their extremities are exquisitely sensitive. With the antennæ, these insects recognise their queen, and appear to communicate to each other their joys and sorrows. For instance, if a colony be deprived of its queen, bees may be seen rushing about the hive, and, with a nervous twinge, crossing their antennæ and conveying the intelligence of their forlorn state. The sense of touch is here most acute. Huber points out a moonlight night as the best time for observing the antennæ in this respect. The bees guarding against the intrusion of moths, and not having light enough to see fully, circumambulate their doors like vigilant sentinels, with the antennæ stretched right before them; and woe to the moth that comes within reach--the instant it is felt, its death follows. The sense of hearing has been denied bees, whilst others contend that these organs are situate in their antennæ. The sounds which bees emit, particularly at swarming time, are conclusive that they possess this faculty; the only reason for arriving at an opposite conclusion seems to be, that no precise organ of hearing can be found. Naturalists are now more united in the opinion that the seat of hearing is here located. The
