Roberson Day started the Children’s Homeopathic Dispensary at Shepherd’s Bush around 1920. The Dispensary was amalgamated with the London Homeopathic Hospital in 1937, and thus became part of the Children’s Outpatient Department there.
John Roberson Day is listed in both of Garth Wilkinson’s address books at 31 Nelhenhall Gardens, Fitzjohn’s Avenue, Hampstead, and at 35 Queen Anne Street, Cavendish Square, W (presumably his consulting rooms?)

In 1887, Edmund Becket Lord Grimthorpe, Chairman of the Governing Body, proposed homeopaths and homeopathic supporters as nominees to the Margaret Street Infirmary, and the Board of the Hospital clearly stated that homeopaths were not ineligible, and John Beckett, J Roberson Day, Kenneth William Millican, and Charles Lloyd Tuckey, were duly appointed,
Roberson Day’s publisher was J. Epps and Co Ltd. J Roberson Day wrote Sea Water Treatment, Sea Water Treatment in the Light of Recent Research, Adenoids Treated without Operation, Childhood in Health and Sickness, he edited the International Homeopathic Medical Directory with Ethelbert Petrie Hoyle, and he submitted many cases and articles to various homeopathic publications, and he lectured widely on homeopathy,
