teeth, nor other organs usually connected with it. Close by the root of these horns, in a kind of projecting knob, is placed a pair of eyes of great brilliancy. Each of these eyes, though they appear to be one only to the naked eye, are discovered by the microscope to consist of six round eyes. The head is a neck or thorax of a singular conformation. Like its horns, this organ also admits of movements of an uncommon kind. It can be lengthened to a considerable degree, or shortened so as totally to disappear, at the pleasure of the animal, nearly after the same manner, to appearance, as a pocket telescope can be lengthened or shortened. The creature is, provided with six legs, like many other insects; but their articulations are so disposed, that it cannot move forward, but must of necefsity, when it changes place, move backward. From this conformation of body its habits would seem to have been formed, if we were to suppose that these habits had been the result of reasoning. To speak more philosophically, however, it behoves us to say, that it has been endowed with such instinctive propensities, as enables it to employ all these peculiarities of conformation in a most wonderful manner to provide for its own subsistence.

That the reader may be able to form a more distinct notion of this singular creature, it is represented in the figure page 103 at A in its natural size, as viewed from above, with its neck contracted, and at B with its neck stretched to its full length; in which figures c is the horns, y a pair of very fine antennæ that spring out below the horns and immediately above the knob

which are short, m the second pair, which are longer. The third pair of legs are under the body, and not seen in these figures, but appear in their natural position on the side view which is given of the same insect magnified to about double its size at C, in which the same letters refer to the same objects as above, n being one of the hinder legs. The horns here are represented as if crofsed.
