What is the right way to do the wrong thing?

I don't see anything about a 1834 Land act, but instead the Act of Feb 1805 which set the c4 as the BB intersect. But, I did find the information on Mr Justin Butterfield and his un-authorized instructions of 1849-1851.

Here is a nice pdf discussing this very issue:

Dual Center of Sections

If it can be shown that during some years that these instructions were followed, and that the corner was set by them, it may be the legal c4.
