In 1893 he was appointed physician to St Thomas' Hospital, London; he later was appointed a Consulting Physician and Governor of St Thomas' and the Royal Brompton Hospital, and was a Consultant to the Commercial Union Assurance Company, as well as numerous other boards, councils and advisory positions.

[4] In August 1931 Acland was posthumously awarded the Order of the Nile (2nd class) for his services to the Sudan Government.

[7] Acland became posthumously involved in the Jack the Ripper Royal conspiracy theory when Thomas E. A. Stowell suggested in a 1970 article in The Criminologist that Sir William Gull, the Royal doctor, attempted to certify Prince Albert Victor, Duke of Clarence and Avondale, as the Ripper.

Stowell claimed that his main source was Gull's daughter Caroline, Acland's wife.

Knight claims that Gull afterwards became insane and was certified in an asylum under the name "Thomas Mason" and a sham funeral service carried out in the pretence that he had died.

[8] Cited as evidence in support of the theory is the fact that Acland signed his father-in-law's death certificate.

He said, "He (Stowell) had been sitting on this thing for 30 years and would have welcomed the chance to test public reaction."
