I assumed the "mad" part was just some archaic term.
Curious whether it does actually mean something or if it is just a typo.
It’s listed as a form of made in the OED but without any examples close to the 19th century. Webster has this spelling.
It's just a typo. The original has "made". I was expecting the text to be a bit more corrupt, but it looks clean and is probably not an OCR type, but a normal human one.
I'm suspecting a meaning of "marked by uncontrolled excitement". Given deliberate language of the article otherwise.
