In the rough draft of the Bill of Rights, the right to keep and bear arms was the 5th.

That version is:

***

A well-regulated militia, being composed of the body of the people, being the bell security of a free state, the right of the people to keep and bear arms shall not be infringed, but no one religiously serupulous of bearing arms, shall be compelled to render military service in person.

So they cleared up the whole conscientious objector thing too way back then.

The second proposed amendment was:

***

No law varying the compensation to the members of Congress shall take effect until an election of Representatives shall have intervened.

***

That one got shelved for a while. It was ratified as the 27th amendment in 1992!

 The proposed congressional pay amendment was largely forgotten until 1982, when Gregory Watson, a 19-year-old student at the University of Texas at Austin, wrote a paper for a government class in which he claimed that the amendment could still be ratified. He later launched a nationwide campaign to complete its ratification.[2][3] The amendment eventually became part of the United States Constitution, effective May 5, 1992
