Co. E, 20th Texas Cavalry, William S. Willis

My gr gr grandfather, William S. Willis was in Bass'Regiment of the 20th Texas Cavalry. I have received paperwork on him from Hill College in Hillsboro, Texas. They were extremely thorough in their research. However, they made a note that the film was bad and difficult to read. Unfortunately, his Surgeons Certificate of Disability has an unreadable date of disability and discharge. It says, see Chapter 1, Vol. --3 207 on the bottom. I have no idea where to find this information, and would appreciate any help. Thank you.
