I struggled up on my feet and proceeded to carry the big vessels to the river bank, where I intended to construct the raft. The effort to take each heavy bottle those few metres seemed almost beyond me in my exhausted state. At last I proceeded to strip the floor of the hut, which had been made with split _assahy_ palms (_Euterpe oleracea_ L.), in order that I might make a frame to which I could fasten the bottles. With a great deal of persuasion I got Filippe and Benedicto to help me. The long pieces of _assahy_ were too heavy for our purpose, and we had the additional trouble of splitting each piece into four. It was most trying work in our worn-out condition. Then we had to go into the forest and collect some small liane, so that we could tie the pieces together, as we had no nails and no rope.

In many of the Synaptidae the anchors are replaced by calcareous rods bent in the form of an S, which are said to act in the same way. Others, such as those of the genus Ankyroderma, have anchors which project considerably beyond the skin, and, according to Oestergren, serve "to catch plant-particles and other substances" and so mask the animal. Thus we see that in the Synaptidae the thick and irregular calcareous bodies of the Holothurians have been modified and transformed in various ways in adaptation to the footlessness of these animals, and to the peculiar conditions of their life, and we must conclude that the earlier stages of these changes presented themselves to the processes of selection in the form of microscopic variations. For it is as impossible to think of any origin other than through selection in this case as in the case of the toughness, and the "drip-tips" of tropical leaves. And as these last could not have been produced directly by the beating of the heavy raindrops upon them, so the calcareous anchors of Synapta cannot have been produced directly by the friction of the sand and mud at the bottom of the sea, and, since they are parts whose function is _passive_ the Lamarckian factor of use and disuse does not come into question. The conclusion is unavoidable, that the microscopically small variations of the calcareous bodies in the ancestral forms have been intensified and accumulated in a particular direction, till they have led to the formation of the anchor. Whether this has taken place by the action of natural selection alone, or whether the laws of variation and the intimate processes within the germ-plasm have cooeperated will become clear in the discussion of germinal selection. This whole process of adaptation has obviously taken place within the time that has elapsed since this group of sea-cucumbers lost their tube-feet, those characteristic organs of locomotion which occur in no group except the Echinoderms, and yet have totally disappeared in the Synaptidae. And after all what would animals that live in sand and mud do with tube-feet?

After the battle of the Metaurus, the chief interest of the war was transferred to Spain and Africa. The Roman armies were led by a youthful hero, perhaps the greatest man that Rome ever produced, with the exception of Julius Caesar. The remaining period of the war is little more than the history of P. Scipio. This extraordinary man was the son of P. Scipio, who fell in Spain in B.C. 212, as already related. In his early years he acquired, to an extraordinary extent, the confidence and admiration of his countrymen. His enthusiastic mind led him to believe that he was a special favorite of heaven; and he never engaged in any public or private business without first going to the Capitol, where he sat some time alone, enjoying communion with the gods. For all he proposed or executed he alleged the divine approval: he believed himself in the revelations which he asserted had been vouchsafed to him; and the extraordinary success which attended all his enterprises deepened this belief.
