It was interesting to note that a Brazilian expedition had discovered some fossil bones of a gigantic animal some 200 kil. south-west of that place, and other remains of a giant animal had been found by another Brazilian expedition on the banks of the Paranatinga River, some 400 or 500 kil. north-east of our position.
We were encamped on the bank of the Rio Pedra Grande—the stream of that name which we had passed that day being merely a tributary. During the night we had observed a double-ringed lunar halo. The moon was almost full. From the horizon directly under the moon were innumerable radiations, not converging toward the moon but, curiously enough, the first two at a tangent to the larger halo, the others at equal intervals on each side.
At sunrise, before the rain-storm began, we were treated to wonderful cloud and light effects. The lower portion of the sky, of brilliant yellow and vivid green, was surmounted by golden and red streaks of wonderful vividness. Later, over the great natural gateways, the sky formed itself into concentric arches of blazing yellow and red, rendered intensely luminous by contrast with the heavy black clouds which were fast collecting overhead. No sooner was the sun well above the horizon than we came in for a heavy downpour.
