These are connected together by ligaments. The +Head+, in common with that of other creatures, is the inlet for nutrition and the principal seat of the organs of sensation.--Of nutrition and sensation I shall speak in their appropriate places. The +Trunk+ is the intermediate section of the body between the head and the abdomen: it approaches in figure to a sphere, and is the seat of the organs of motion; it contains the muscles of the wings and legs which proceed from it, and is the main prop, or as it were the key-stone, of the other two sections. The upper side is called _thorax_ or the _chest_, the under side _pectus_ or the _breast_. The +Abdomen+ is the third section of the body, posterior to the trunk; it is divided into six rings or segments, which, by sliding one over another, serve to shorten or lengthen the body. It is the seat of the organs of generation, and principally of those connected with respiration; and contains also the anus and the sting. The upper part is called _tergum_ or the _back_, the under side _venter_ or the _belly_. +The Head.+ The most remarkable part of the head is the +Proboscis+, of which so good an account has been given by +Dr. Evans+ that I shall describe it nearly in his words. It is not so much the mere simplicity of nature, which excites our wonder and admiration, as that apparently complex structure, which operates with all the ease of the simplest machinery. Of this we have not a more striking instance than in the proboscis of the labouring bee: though the component parts of the proboscis are scarcely discernible by the naked eye, yet are they far more complicated than the elephant's stupendous trunk. It consists of no less than five distinct branches; namely, a central trunk, or tongue, and four horny scales, tapering to a point, convex outwards and concave towards the trunk; the two outer ones so sheath the inner as to appear but one single tube: by a joint in the middle they bend, or extend all at once, carrying with them the unarticulated tongue, which is cylindrical, and about the size of a man's hair, and appears through a magnifier to be composed of successive rings. It has probably as many short muscles as the tongue of a fish, which are capable of moving it in all directions; and towards its termination is furnished with hairs or villi, some of which at the point are very long, and seem to act like capillary tubes. +Mr. Wildman+ assures us, that he has seen the trunk growing bigger and less by turns, swelling the instant the bee sucked; and this alternate lessening and enlargement propagated from the extremity to the root. What a delicate apparatus of invisible muscles must perform this office! The tongue is capable of being contracted and folded up at pleasure; for if it were constantly extended, it would be exposed to injury: when at rest, therefore, it is doubled up by means of its joint, and lies in a very small compass; the
