This OP raised questions in my mind. I searched online several weeks back and could not find R.S. 2032. The Revised Statutes were also difficult to find online. I came across a .pdf by doing site searches for files and found the R.S. was codified in Volume 18 Part I. Online search engines for this returned no results. This included constitution.org and memory.loc.gov . I was waiting for an opportunity to travel to the closest Federal Repository (60 miles away). Fast forward to yesterday; and Alfred Adask posts this blog; serendipity.

The Freedmen statutes are on page 358.
