Medical Director's Office, 31 March 1864
Sir
I called your attention to the fact that you had not observed the directions given you in regard to the closure of Divns and their use only when required.
No sufficient excuse has been received from you and the daily reports from the Hospl show that these instructions are disregarded.
Very Respy &c.
Wm. A. Carrington
Med. Director
Surg. Hancock
