Autograph letter signed to A. Byham,

Civil engineer (1804-63). 2 pp, 12mo. "Dear Sir / Will you excuse the Son of your old Surveyor General so far as to send me a printed copy of the regulations under which Boys come for examination at Woolwich Academy: My Boy will probably be finding his way there & I want to prepare him to meet the Points of examination: - If you have not any of the printed copies perhaps by passing this not into an adjoining room you will be able to send one by my messenger who will wait, & you will much oblige yours faithfull / W. S. Moorsom". Negligible traces of mount adhering to one edge of verso. Moorsom's father was son of Admiral Sir Robert Moorsom, K.C.B. (died 1835), and father of Captain William Robert Moorsom (1834-58), one of the heroes of the Indian Mutiny.
