toothc. You will admire the wisdom of this admirable contrivance, when you reflect that these larv are not fitted to pursue their prey with rapidity, like most predaceous animals; but that they steal upon them, as De Geer observesd, as a cat does upon a bird, very slowly, and as if they counted their steps; and then, by a sudden evolution of this machine, take them as it were by surprise, when they think themselves safe. De Geer says, it is very difficult for other insects to elude their attacks

; que de ce trou partent immédiatement cinq spirales qui sont coupées un peu après par un profond sillon, marque restante du point d'insertion de ce qu'on a nommé les cinq stigmates. Les spirales continuent ensuite leur évolution autour de la gyrogonite, et lui ont fait donner ce nom par M. de Lamarck qui croyoit voir en eux un genre de coquille. Des fruits du chara vulgaris ont été examinés par nous, et ilous avons reconnu non-seulement les faits ci-dessus, mais encore que ce qu'on nomme

activity and zeal for our service. As no ship could with propriety venture near us to assist in turning the Esk over, on account of the hazardous position of the ice around her, we had no other means of performing this singular evolution than by attaching purchases to the ice from the ship. We proceeded as follows: A new hawser of 9 inches circumference, was taken under the ship's bottom, the end clenched to the main-mast, and the [page] 45

eastward (wind at north), the distance of about two miles; but in attempting to wear and return, the ship, instead of performing the evolution, scudded a considerable distance to leeward, and was then reached out to sea; thus leaving fourteen of her crew to a fate the most dreadful, the fulfilment of which seemed almost inevitable. The temperature of the air was 15 or 16 of Fahr. when these poor wretches were left upon a detached piece of ice, of no considerable magnitude, without food, without

could see no termination. The Mars of Whitby, and another vessel, which closely followed us as we penetrated the exterior of the ice, being in better trim than the Esk, performed the evolution with ease, and were in a few minutes out of sight. In this dreadful situation, we lay beating against the opposing ice, with terrible force, during eight successive hours; all which time, I was rocked, with no agreeable feeling whatever to console me, at the top-gallant-mast-head, directing the

shewn, that in the Naiad and in some other families, the thickened cotyledonous end of the germ, and, in the Palm and Junce , the lateral tubercles, furnish the apparatus, by the help of which the further evolution of the embryon takes place. In the Scitamine and in the Grasses, the vitellus or the scutellum are the organs by which the sap, when prepared, is conducted to the embryon, and by which its evolution is favoured. We must here also, as in most of the lower families, take into account the

By studying these relations, by carefully comparing the structure with the function, we arrive at a sure knowledge of the nature of organs. 176. Mistakes in this respect are committed, when we overlook three things, namely, the Abortion, Alteration, and Union of Organs. Respecting all these three phenomena of nature we must now give a more particular account. A. Of Abortive Organs. 177. The abortive state of an organ is often the consequence of an imperfect evolution. The cause lies not

corresponding to the pattern which properly belongs to each plant. That electricity performs an important part in impregnation, has long been suspected; and the contraction of electrical matters in the blossom, and in the parts of fructification, seems to favour this idea. 382. As we thus consider the stimulus of the pollen to be a necessary condition of the evolution of seed from the ovula, we must at the same time defend ourselves against both the ancient and later objections to this

Palms, Sarmentace , and Coronari , onwards to the Iride , Scitamine , and Orchide , where it is evolved in the greatest magnificence. Although these, in some respects, are families of a lower rank, we yet thus see, that in the progress of nature towards a more complete evolution of forms, it is seldom that a harmonious construction of all the parts takes place, but that commonly one organ is exquisitely fashioned, while others remain imperfect; since the Pine tribe, the Armentace and Urtiee

multiplicate, and perfectly double or full. Cultivation stimulates the organs of nourishment, and the instruments of propagation pass into these. Yet there are inferior gradations of this disposition to become double, in which the organs of fructification remain unconfined in their evolution, and in the exercise of their functions. When in the Hydrangea of our gardens, the parts of the calyx expand, and become of the nature of a corolla, the evolution of the filaments suffers so little by this
