In January 1848, Wells self-experimented with chloroform for a week. He became increasingly deranged. One day, delirious, Wells rushed out into the street and threw sulfuric acid over the clothing of two prostitutes. He was committed to New York's infamous Tombs Prison. As the influence of the drug waned, Wells' mind started to clear. In despair, he realised the horror of what he had done. Wells then committed suicide, slitting an artery in his leg with a razor after inhaling an analgesic dose of chloroform to blot out the pain.
