From 1857, both adopted by the 6th Session of the Texas Legislature and printed up in Galveston.
From the Texas Reference Library:
In 1854 the fifth Legislature passed an act requiring the Governor to appoint a commission to codify the civil and criminal laws of Texas. The Commission proposed four codes, but only the Code of Criminal Procedure and the Penal Code were adopted by the Legislature. They are commonly referred to as the Codes of 1856 or the Old Codes.
It would be worth comparing these with the current versions.
- Penal Code
- Code of Criminal Procedure.
