Sorry, no etymologies found.
This extraordinary man, living the life of a recluse in his own observatory, which was situated in a lonely part of the country, had, or at any rate, believed that he had, opened up a communication with the inhabitants of Mars, by means of powerful electric lights, flashing in the manner of a signal-lantern or heliograph.
It seemed to be the glimmer of a vessel's signal-lantern rising out of the curve of the sea.
Dead to windward he at last discovered a green light, which he had no doubt was the starboard signal-lantern of the Sylph.
I could not make out the inscription on the river side of the monument and, seeing a signal-lantern tied to a scow moored to the bank near by, I untied it and by its light was able to read the tribute of the city to the memory of the priest and the explorer "who first of known white men had passed that way," having travelled, as it recites, "two thousand five hundred miles in canoes in one hundred and twenty days."
