we saw Henry makes an on-camera attempt to steal the brain of the hanged criminal for use in the Monster
Which raises a question. Doesn't Henry make a comment that the brain is useless because the neck's been broken? Still trying to figure the logic on that one. After all, the brain in the jar appears to have no spine piece attached, so why couldn't Henry have used the brain of the hanged man, since it would have been possible to sever the brain above the damaged done by the hangman's noose?
