Remember the Rainforest 1
(1)The luminosity of insects is, in tropical countries, much more vivid than in Europe. The phosphorescent light, which radiates the Firefly (Elater Noctilucus, Ignitus and Phosphoreus),
exceeds six times in intensity of the European fireflies (Lampirys Noctiluca);
But the most extraordinary in the case is above all its number and seeing the observer surrounded by such luminosity. And to see such a swarm of insects to fighting in incessantly in vain, sometimes pert, far away, or around the traveler, in the thicknesses of the forest reminds one of a real fire, and the deep darkness of the night increases the impression of the wonderful spectacle.
I observed that the great humidity of the air, in particular before or after the rain, has an influence on the activity of such animals: they circulate more quickly; And the luminous shining, sometimes light blue or reddish, stays uniformly strong. On dry nights, especially when wind blows, the phosphorescence is much weaker, and the insects seem to be more slow. They are noted in all epochs of the year, but are always greater from November to April than in the other months.
The great Lanternarias, Fulgora Diadema and Lanternaria, L. appear at the equator; Most of the other species, we also saw in the southernmost regions, particularly in the virgin forests of Minas and Bahia. We counted eleven species.
(2) We designate the Amazon River manatee with the name Delphinius Amazonicus, because the geographic propagation of this species seems to present one of its distinctive characteristics.
At least until now, one does not know any other of the genera that is preserved in such quantity, preferably in fresh water. It appears not only in the Amazon and Solimoes, but also in the west, in the rivers of Mainas, and, according to some Spanish fugitives, in Ega, also on the shores of Choco and Peru. These men claim that the manatee lives in the cold waters of the rivers, without being chased by the crocodiles, which, as already noted by Acosta and Ulloa, do not support the icy water, which descends from the Andes to the coastal rivers. As for the animal remedies used by the Indians, I must also mention that they employ the upper vertebra of the manatee, reduced to powder, with much efficiency, against hemorrhages.
