Educated at St Bartholomew's Hospital at a time when Sir James Earle, John Abernethy, and John Painter Vincent were its leading surgeons. He was a favourite with Abernethy, who reposed great trust in him, and whose house at 14 Bedford Row he afterwards occupied for over thirty years of a successful practice. He became House Surgeon at St Bartholomew's Hospital and Surgeon at the Aldersgate Street Dispensary. On May 19th, 1824, being then hardly 30 years of age, he was elected Assistant Surgeon to this hospital, when he obtained 93 votes, Samuel Cooper 82, and F C Skey 21. He had already gained the Jacksonian Prize in 1818 with his essay "On Scrofula", the manuscript of which, now in the College Library, was in 1821 expanded into "A Treatise on the Nature and Treatment of Scrofula, describing its Connection with Diseases of the Spine, Joints, Eyes, Glands, etc.... To which is added a brief account of the Ophthalmia so long prevalent in Christ's Hospital"; this was published in London as an octavo volume during that year. He was Surgeon to Christ's Hospital, and on Feb 10th, 1847, on the resignation of Vincent, he was appointed full Surgeon to St Bartholomew's Hospital. He occupied this position with great credit and success, and to the advantage of the hospital, until March 21st, 1861, when he was compelled to resign owing to failing health. He was one of the few Surgeons at St Bartholomew's Hospital who held no office at the College. As a surgeon Eusebius Lloyd was very successful. Abernethy placed unlimited confidence in him and frequently entrusted to him his private practice. British surgery owes some special innovations to Lloyd. His radical cure of hydrocele by the introduction into the tunica vaginalis of red precipitate, his mode of injecting naevi with liquor ammonia, and his median operation of lithotomy, were much used. He was conspicuous for his success in purely medical cases; and he held that every good surgeon should also be an accomplished physician. Lloyd had been in failing health for some years, bronchitis causing him much trouble. He left 14 Bedford Row, and died at Ventnor on March 4th, 1862. Publications:- Beside the work above mentioned, Lloyd also wrote :- "On the Treatment of Ulcers in the Legs by the Subcutaneous Division of the Inflamed Varices in their Neighbourhood." - *Quart Jour of For Med and Surg* 1822, iv, 150. "On the Division of the Stricture in Strangulated Hernia without opening the Sac." - *Lond Med Gaz*, 1835-6, xvii, 967. "On the Treatment of Naevi Materni by Injection." - *Ibid*, 1836, xix, 13. He also contributed to the *Lancet* and *Med-Chir Trans*.
