English most likely, but sometimes they surprise you with Japanese.
Since The Time Machine is told in the first person (or, rather, from two first-person points of view ), the tone that comes through is the attitude of the two narrators. The two narrators' tones are similar to each other – especially because they are both somewhat fragmented. That is, in parts of the novel the narrators are scientific and precise, but at other times, they are emotional and sentimental.
