About a month before his death, and whilst in the best of health, he went over to Dublin and "spent the night in an hotel bedroom infested by gases from an adjacent watercloset". He died a fortnight later, probably of typhoid, on June 4th, 1874, at New Ross, Wexford. His photograph is in the College Album. He was buried in the Roman Catholic Cemetery at Kensal Green. He had paid special attention to the subject of infanticide, and gained in 1856 the Fothergillian Medal of the Medical Society of London. He had besides, in 1857, read a paper to the Medical Society "On a Case of Arsenic Poisoning by a Large Dose, where the Symptoms were Unusually Delayed and Suffering Prolonged".
