Iodides.--The iodide treated with the oil of vitriol, instantly produces a considerable deposit of iodine; and if the mixture be heated, intense violent vapors are disengaged. The reaction is due to the decomposition of oil of vitriol by iodohydric acid, water and sulphurous acid being formed, and iodine set free. The iodides in solution are decomposed by chlorine, iodine being precipitated, the smallest quantity of which in solution is instantly detected by its imparting to starch an intensely blue color.英文原著 · 《American Hand Book of the Daguerreotype》
The common sulphuric acid is made by burning sulphur, which forms sulphurous acid. To convert this into sulphuric acid and gain more oxygen, nitric acid, which is rich in that body, is added. It forms a limpid, colorless fluid, of a specific gravity of 1.8. It boils at 620 deg.; it freezes at 15 deg. It is acrid and caustic, and intensely acid in all its characters, even when largely diluted.英文原著 · 《American Hand Book of the Daguerreotype》

"You must be ready tomorrow morning," he called. "I have business plans which can't be delayed," and he turned away muttering rather sulphurous words.英文原著 · 《He Fell In Love With His Wife》
Brave, good, and true, I see him stand before me now, And read again on that young brow, Where every hope was new, HOW SWEET WERE LIFE! Yet, by the mouth firm-set, And look made up for Duty's utmost debt, I could divine he knew That death within the sulphurous hostile lines, In the mere wreck of nobly-pitched designs, Plucks hearts-ease, and not rue.英文原著 · 《Hero Tales From American History》
