“Who is—or who was—the hooded woman with the owl? Do you know?”
“Well!” said Ikey, holding up his cap with one hand while he scratched his head with the other, “they say, in general, that she was murdered, and the howl he 'ooted the while.”
This very concise summary of the facts was all I could learn, except that a young man, as hearty and likely a young man as ever I see, had been took with fits and held down in 'em, after seeing the hooded woman. Also, that a personage, dimly described as “a hold chap, a sort of one-eyed tramp, answering to the name of Joby, unless you challenged him as Greenwood, and then he said, ‘Why not? and even if so, mind your own business,’” had encountered the hooded woman, a matter of five or six times. But, I was not materially assisted by these witnesses: inasmuch as the first was in California, and the last was, as Ikey said (and he was confirmed by the landlord), Anywheres.
— Charles Dickens, The Haunted House: The Mortals in the House
There is nothing written about “being taken with fits and hold down in them” in any dictionary.
This is what I don't understand.
