To his sailing men, Ambroise gives them some of his own stores of rations (and, being the leader of the party, he no doubt had more than them) and promises to split his pay among them next time he gets his paycheck. Then he addresses the excitement, and says that the sentiment is noted, but he himself doesn't have any more excitement than them. Although he does say that they can borrow his collection of books written by himself at any time.
At the sight of the Buddhists, Ambroise asks what is wrong with them. When informed, Ambroise scolds the architects, and tells them to build elsewhere. He says that France should build a reputation for respecting all cultures and religions, so as to reduce risk of revolts on the basis of cultural freedom in the future.
