I Have Proved By Experiments Published In 1797, That The
Shining Of Wood Is Extinguished In Hydrogen Gas, And In Pure Azotic
Gas, And That Its Light Reappears Whenever We Mix With It The
Smallest Bubble Of Oxygen Gas.
These facts, to which several others
may be added, tend to explain the causes of the phosphorescence of
the sea, and of that peculiar influence which the shock of the
waves exercises on the production of light.
When we were between the island of Madeira and the coast of Africa,
we had slight breezes and dead calms, very favourable for the
magnetic observations, which occupied me during this passage. We
were never weary of admiring the beauty of the nights; nothing can
be compared to the transparency and serenity of an African sky. We
were struck with the innumerable quantity of falling stars, which
appeared at every instant. The farther progress we made towards the
south, the more frequent was this phenomenon, especially near the
Canaries. I have observed during my travels, that these igneous
meteors are in general more common and luminous in some regions of
the globe than in others; but I have never beheld them so
multiplied as in the vicinity of the volcanoes of the province of
Quito, and in that part of the Pacific ocean which bathes the
volcanic coasts of Guatimala. The influence which place, climate,
and season appear to exercise on the falling stars, distinguishes
this class of meteors from those to which we trace stones that drop
from the sky (aerolites), and which probably exist beyond the
boundaries of our atmosphere.
