Regarding the original French version:
""Please note that the correct title of Vattel's Book I, Chapter 19, section 212, is “Of the citizens and naturals”. It is not “Of citizens and natives” as it was originally translated into English. While other translation errors were corrected in reprints, that 1759 translation error was never corrected in reprints. The error was made by translators in London operating under English law, and was mis-translated in error, or was possibly translated to suit their needs to convey a different meaning to Vattel to the English only reader. In French, as a noun, native is rendered as “originaire” or “indigene”, not as “naturel”. For “naturel” to mean native would need to be used as an adjective. In fact when Vattel defines "natural born citizens" in the second sentence of section 212 after defining general or ordinary citizens in the first sentence, you see that he uses the word "indigenes" for natives along with "Les naturels" in that sentence. He used the word "naturels" to emphasize clearly who he was defining as those who were born in the country of two citizens of the country. Also, when we read Vattel, we must understand that Vattel's use of the word "natives" in 1758 is not to be read with modern day various alternative usages of that word. You must read it in the full context of sentence 2 of section 212 to fully understand what Vattel was defining from natural law, i.e., natural born citizenship of a country. "

Translating the french text: "les naturels, ou indigenes, sont ceux qui sont nes dans le pays, de parents citoyens"
To English, gives this: "the natural, or indigenous, are those born in the country, parents who are citizens"
