I'm not very knowledgeable about this but by 1888 cocaine had been isolated from the coca leaf and was being marketed. Witness the references in the Sherlock Holmes stories.
Jack seemed to be frenzied in what he did. My first thought is PCP but that wasn't around then. Could cocaine be a part of the picture here? I don't know enough about the symptoms of cocaine intoxication to say.
