H2S

Chemicals which induce the release of hydrogen sulfide, increase endogenous production of hydrogen sulfide, or somehow yield hydrogen sulfide as a metabolic byproduct...? Besides, of course, hydrogen sulfide.

THE MOST CONFUSING SENTENCE I HAVE EVER READ?

"And if, as we have seen, the most intelligent of them did not delude themselves about the materialist origins of their prejudice against the Mulattoes, we yet will make a great mistake if we think that they were hypocrites when they claimed that a white skin guaranteed to the owner superior abilities and entitled him to a monopoly of the best that the colony afforded."
