The principles we have just established were cruelly violated by the Spanish. The Inca Athualpa1 could only be judged by the law of nations ; they judged him by civil and political laws : they accused him of having had some of his subjects put to death, of having had multiple wives, etc. And the height of idiocy was that they did not condemn him by the political and civil laws of his country, but by the political and civil laws of their own.
