That there is a close likeness between all these bodies is obvious from the fact that when any of them is strongly heated, or allowed to putrefy, it gives off the same sort of disagreeable smell; and careful chemical analysis has shown that they are, in fact, all composed of the elements carbon, hydrogen, oxygen, and nitrogen, combined in very nearly the same proportions. Indeed, charcoal, which is impure carbon, might be obtained by strongly heating either a handful of corn, or a piece of fowl's flesh, in a vessel from which the air is excluded so as to keep the corn or the flesh from burning. And if the vessel were a still, so that the products of this destructive distillation, as it is called, could be condensed and collected, we should find water and ammonia, in some shape or other, in the receiver. Now ammonia is a compound of the elementary bodies, nitrogen and hydrogen; therefore both nitrogen and hydrogen must have been contained in the bodies from which it is derived.
However, thanks to the great civility of the managers of the Booth Line at Manaos, and to the extreme thoughtfulness of the captain of the _Atahualpa_, I was made quite comfortable in the chart-room of the ship, which was as far away as possible from the noise. We were most of the time in mid-stream. The river was so wide that we could not see anything on either side. We steamed up day after day, occasionally passing islands of some beauty rising above the muddy waters of the Solimoes. Navigation of that river was difficult, as the navigable channels were constantly changing, islands disappearing and new islands forming all the time. Elich Island, in the Timbuctuba group, was fast disappearing, while another island was forming just below it.
