In the long years of imprisonment which followed--the doom of the stake being averted only by powerful intercession with the Pope--Bacon had leisure to meditate on the value of all he had done to enlarge the understanding and extend the knowledge of his species. "The prelates and friars," he wrote in a letter which still remains, "have kept me starving in close prison, nor will they suffer any one to come to me, fearing lest my writings should come to any other than the Pope and themselves." He reflected that of all living men he stood well-nigh alone in the consciousness that in the greatest of his inventions he had produced a discovery of incalculable value, but one for which on every account the time was not ripe. "I will not die," he said, "without leaving to the world the evidence that the secret was known to me whose marvelous power future ages shall acknowledge. But not yet shall it be revealed. Generations must pass away and the minds of men become better able to endure the light of science, before they can profit by my discovery. Let him who already possesses knowledge, guess the truth these words convey." And in place of the directions by which Hubert de Dreux had been guided, he altered the sentence as follows: "Sed tamen salis petre, LURU MONE CAP UBRE et sulphuris." The learned have found that these mystical words conceal the anagram of _Carbonum pulvere_, the third ingredient in the composition of Gunpowder. [From a Month at Constantinople.] GLIMPSES OF THE EAST. BY ALBERT SMITH. A TURKISH BATH.--The second day I was at Constantinople I had a bath, in the proper Turkish fashion; and this was quite as novel in its way as every thing else had been. The establishment patronized was the head one in Stamboul; and we went from the street into a very large hall, entirety of marble, with a gallery round the walls, in which were couches, as well as down below. On these different visitors were reposing: some covered up and lying quite still, others smoking narghiles, and drinking coffee. Towels and cloths were drying on lines, and in the corner was a little shed, serving as a Cafe.
