With the microscope I could have seen but a part and not the whole. A very considerable enlargement would also have exaggerated the merely secondary details--such as the scanty hairs with which the ant is provided. Finally, its mobility would not have suffered me to keep it in the focus of the microscope; but the lens, as easily shifted as itself, followed it in all its motions. Not, however, without some difficulty. It was lively, alert, disquieted, and impatient to quit the table. I was looking at it in the middle of the sheet, when it was already nearly at the edge. I was obliged to _etherize_ it a little, so as to stupefy it, and render it less uneasy. It appeared very clean, and highly varnished. Though a neuter, and not a female, its belly was rather large, and was joined to the chest by two small swellings. From the chest the head, which was strong and nearly round, detached itself cleanly and distinctly. This head, seen as it were _en masse_, resembled a bird's. But instead of a beak it had a circular prolongation, in which, on attentive examination, I detected the reunion of two tiny crescents joined at the point. These were its teeth, or mandibles, which do not operate like ours, from above to below, but horizontally and sideways. The insect employs its mandibles for the most widely different purposes; they are not only its weapons and instruments of mastication, but the tools it uses for every art, supplying the place of hands in masonry, plastering, carving, and in lifting and transplanting burdens which are frequently of enormous weight. It was well for it that its body was wrapped in a complete coat of mail. The ether affected it but slightly, and only stupefied it. After a moment's immobility it partly recovered, and made a few movements like those of an intoxicated person, or as if it were affected with a fit of vertigo. It seemed to say, "Where am I?" and endeavoured to make out the ground where it was walking, the great sheet of white paper. It attempted a few tottering steps, tumbling first on one side and then on the other. It carried before it a couple of instruments which at first I took to be feet, but which I found, on more careful inspection, were wholly different.
