It is used to dissolve the sensitive salt of silver which remains unchanged during the exposure in the camera. It has the property of readily dissolving the chloride, bromide and iodide of silver. It should be pure and free from sulphuret of sodium; should this last be present, it will cause brown spots of sulphurated silver upon the Daguerreotype impression.
One day there were found on the shore two little boats covered with tarpaulin, which these gentry probably used in their clandestine excursions. In June, 1804, eight Englishmen, perfectly well dressed, in white silk stockings, etc., were arrested, and on them was found sulphurated apparatus with which they had intended to burn the fleet. They were shot within an hour, without any form of trial.
Pure atmosphere does not act upon silver; but we do not have this about in our operating rooms, as it is more or less charged with sulphurated hydrogen, which soon tarnishes the surface of the plate with a film of brown sulphurate. It is this that sometimes causes the specks which appear on finishing the impression, and are a great annoyance.
In numerous places thick clouds of vapor burst from the ground, with a strong smell of sulphurated water. This solfatara must formerly have been much more active than it is now. The ravine, which has been formed by its destruction of the rock, and is full of lofty heaps of débris, may be one thousand feet in breadth, and quite five times as long.

He then sets about combining metals with sulphur in the moist way, as if that were any more to his purpose than is the making of a stalactite for the explanation of marble. Silver and lead may be sulphurated, as he says, with hepatic gas; but, Has the sulphurated solid ores of those metals, and that of iron, been formed in the moist way, as in some measure they may be by the fusion of our fires?
So when the canoe brought up so violently that all our tinware rolled on Deuce, Dick was merely disgusted. "There she goes again," he grumbled. "You've hooked Canada." Canada held quiescent for about three seconds. Then it started due south. "Suffering serpents!" shrieked Dick. "Paddle, you sulphurated idiot!" yelled I. It was most interesting.
The air smelled of chlorine, iodine, and sulphurated hydrogen, but was breathable. I saw that the principal characteristic of life on Orcon was an organic ability to thrive under almost any climatic conditions.
The secret of this is as follows: The jug contains a little sulphuret of potash, and the words are written with acetite of lead. The action of the exterior air, on, the sulphuret of potash, disengages from it sulphurated hydrogen gas, which, acting on the oxyd of lead, brings to view the characters that before were invislble.
