Final answer:
The provided texts do not contain information about Mr. Rochester or the laughter he hears. The excerpts are from various literary works and do not pertain to the novel 'Jane Eyre' by Charlotte Brontë.
Step-by-step explanation:
The question pertains to whom Mr. Rochester attributes the demonic laughter coming from the third story. However, the excerpts provided do not relate to Mr. Rochester or the source of the laughter he hears. Since the question seems to be referring to the novel Jane Eyre by Charlotte Brontë, where Mr. Rochester attributes the laughter to his servant Grace Poole, the provided texts are not relevant to correctly answering your question. These excerpts depict various scenes of madness, laughter, and eerie occurrences from different literary works, that are not directly connected to the character Mr. Rochester or the scenario described in Jane Eyre.
