Can you show where the notably thrify Founders spend precious public funds to purchase his work for use in the Senate?

Ordered, That the Secretary purchase Blackstone's Commentaries, and Vattel's Law of Nature and Nations, for the use of the Senate.

To answer your question: Yes, I certainly can.
Please note: I have said before, accurately, that Vattel was influential IN THE REALM OF INTERNATIONAL LAW.
So, to repeat the question I asked you before:
The actual text of Article I, Section 8, Clause 10 of the Constitution says:
The Congress shall have Power... To define and punish Piracies and Felonies committed on the high Seas, and Offences against the Law of Nations...
The "law of nations" was NOT simply defined by Vattel. Although he was an influential writer on the subject, there were a bunch of others.
The reference to the "law of nations" in the Constitution is a reference to the law of nations. It is NOT a reference to Vattel's book on the topic.
In fact, the Constitution speaks of "OFFENSES AGAINST THE LAW OF NATIONS."
Did you know there was another book, FAR more widely read and used than Vattel, that has a chapter on precisely that topic, with a title that is almost verbatim to the phrase as used in the Constitution?
The author was quoted by the Founding Fathers SIXTEEN TIMES more often than they quoted Vattel.
And his book's chapter is titled, "OF OFFENSES AGAINST THE LAW OF NATIONS."
That being the case, and given that he was quoted by the Founders SIXTEEN TIMES more often than Vattel, and given that I can certainly show where the notably thrifty Founders spent precious public funds to purchase his work for use in the Senate, would you not now agree that this book, which specifically treats "Offenses Against the Law of Nations," and not Vattel's, is likely the source of the phrase "Offenses against the Law of Nations," as used in our Constitution?
