The strength and beauty of this small creature, had it no other relation at all to man, would deserve a description. For its strength, the Microscope is able to make no greater discoveries of it then the naked eye, but onely the curious contrivance of its leggs and joints, for the exerting that strength, is very plainly manifested, such as no other creature, I have yet observ'd, has any thing like it; for the joints of it are so adapted, that he can, as 'twere, fold them short one within another, and suddenly stretch, or spring them out to their whole length, that is, of the fore-leggs, the part A, of the Scheme, lies within B, and B within C, parallel to, or side by side each other; but the parts of the two next, lie quite contrary, that is, D without E, and E without F, but parallel also; but the parts of the hinder leggs, G, H and I, bend one within another, like the parts of a double jointed Ruler, or like the foot, legg and thigh of a man; these six leggs he clitches up altogether, and when he leaps, springs them all out, and thereby exerts his whole strength at once. - Bees
The figure is a very accurate representation of the Queen, the Worker and the Drone. - Every good mother should be the honored queen of a happy family
The group of bees represents the attitude in which the bees surround their Queen or Mother as she rests upon the comb. - Syrian Ants
The Ant is mentioned twice in the Old Testament, both times in the Book of Proverbs (vi. 6 and xxx. 25). Ants are characterized as being exceeding wise, and in both passages are commended for their diligence in preparing their food in the summer, thus by their fore-sight providing for their winter sustenance. Such is at least the` obvious implication contained in the text. This habit was, and is still, contradicted by some writers, from their knowledge of the ways of European ants, which are dormant in the winter, and therefore stand in no need of food.
