If you're interested in all patients admitted to Way Hospital, Meridian MS, this is the right resource. If, however, you're only interested in one patient who happened to be there in 1865, you would be much better served to review the entry from Way Hospital in the soldier's military service file. You should also be aware that several other Confederate hospitals operated in Meridian from time to time during the war.

The correct reference from National Archives Record Group 109 is Way Hospital (Meridian MS), "A register of patients, Jan 7 - Apr 1, 1865," Chapter VI, volume 665, pages 7 - 360.
