Quote #8
"Then I go back to my compartment. The miserable John Bull who shares it with me is away attending to his master. At last he comes back – very long face as usual. He will not talk – say yes and no. A miserable race, the English – not sympathetic." (2.10.33)

"He has been a long time in America," said M. Bouc, "and he is an Italian, and Italians use the knife! And they are great liars! I do not like Italians." (2.10.51)
