Thus there is a very broad distinction between mineral matter and living matter. The elements of living matter are identical with those of mineral bodies; and the fundamental laws of matter and motion apply as much to living matter as to mineral matter; but every living body is, as it were, a complicated piece of mechanism which "goes," or lives, only under certain conditions. The germ contained in the fowl's egg requires nothing but a supply of warmth, within certain narrow limits of temperature, to build the molecules of the egg into the body of the chick. And the process of development of the egg, like that of the seed, is neither more nor less mysterious than that, in virtue of which, the molecules of water, when it is cooled down to the freezing-point, build themselves up into regular crystals.
We went down all the time on troubled waters, with rocky banks and innumerable obstacles all the way. We went through another terrible and most intricate rapid--the Labyrinth--and passed through a channel only 40 m. wide between high rocky banks. Then, after that, for 9,500 m. we had fair and smooth navigation, with a range of flat-topped hills 300 ft. high, extending from W.S.W. to E.N.E., in front of us to the north-west. Here there was a regular maze of channels, all more or less bad. We did not follow the principal one, which was strewn with rocks, but a smaller one, at the end of which, unfortunately, we found a barrier of rocks which we could not surmount. We had all the trouble of dragging the canoe back up the rapid until we could turn her round into another channel.
