- ELECTED TO FILL THEIR OWN VACANCIES: On April 1, 1853, John Sime, Elcan Heydenfeldt, James M. Taylor, Frederick A. Snyder, and Samuel Flower all resigned from the Assembly. All but Snyder then ran for their vacated seats in the subsequent Special Election, all were reelected, and sworn back into office on April 18th.
- In 1853, Heydenfeldt became the first person to serve in both houses of the California Legislature and the first to go from the Senate to the Assembly.
