Final answer:
The provided excerpts do not show a scene where Victor calls Walton a madman. Such a scenario would likely involve Walton expressing a perilous ambition akin to Victor's, which drove him to madness in Mary Shelley's "Frankenstein."
Step-by-step explanation:
The excerpts provided do not contain a direct interaction between Walton and Victor in which Victor calls Walton a madman. Based on the famous novel "Frankenstein" by Mary Shelley, Captain Robert Walton is a character who narrates the story through letters, and Victor Frankenstein is the scientist who creates the monster.
For Victor to call Walton a madman, it would imply a scenario where Walton expressed an understanding of, or a desire to pursue, dangerous knowledge or actions similar to Victor's own obsessive quest, which pushed him to the brink of madness. Unfortunately, without the specific interaction from Mary Shelley's novel, it's impossible to pinpoint exactly what Walton says that prompts Victor to call him a madman.
