In chapter 5 of 'Frankenstein', Victor conducts scientific experiments all night.
Step-by-step explanation:
In chapter 5 of 'Frankenstein', after running from his room, Victor Frankenstein conducts scientific experiments all night. The line in the text that supports this is, "It was already one in the morning; the rain pattered dismally against the panes, and my candle was nearly burnt out, when, by the glimmer of the half-extinguished light, I saw the dull yellow eye of the creature open" (Shelley, 1818, p. 42).
