Dr. Stoney took up this work about a fortnight before the opening of the Endell Street Hospital under Dr. Garrett Anderson; she is therefore the first woman doctor to work under the War Office in England. Dr. Stoney not only undertakes the photographic branch of the X-ray work, but she diagnoses and reports on the cases from the photographs. Another branch of her work is to use X-rays actually during operations for those surgeons who prefer to operate in this way. She also started a small department for X-ray treatment, which has proved beneficial in certain nerve and goitre cases. Dr. Stoney recently reported that considerably over 5000 cases had passed through her hands since she came to this hospital. She has a staff of V.A.D. assistants, two of whom she has trained in the work sufficiently to enable them to take over X-ray installations. One is now working in Rumania, and the other in London. Dr. Stoney’s splendid work has completely overcome any prejudice which may have attached to her as a woman when she first took up her post. Although she is the only woman doctor in the hospital, she works on an equal footing with the men, except that she holds no military rank. Miss Edith Stoney is a woman of great university distinction, having been wrangler in the Mathematical Tripos at Cambridge. She was an Associate of Newnham College, Cambridge, and Lecturer in Physics to the London University. Astronomy is another subject on which she has lectured, and while at Newnham College she had charge of the telescope. She has also done valuable original work in relation to searchlights. At the beginning of the war Miss Stoney joined the committee of the Women’s Imperial Service League, and helped in the organisation of the hospital unit with which her sister went to Antwerp, fitting up the portable X-ray apparatus, which was subsequently of such great service. After the transfer of the hospital to Cherbourg she continued to assist in the organisation of its supplies. Her real war work, however, may be said to have begun when she retired from her work as Lecturer in Physics in the spring of 1915 and joined the Scottish Women’s Hospitals. Miss Stoney first took up work at the tent hospital at Troyes, where she put up and ran the X-ray department, giving invaluable assistance to the surgeons by the accurate localisation of foreign bodies in wounds. The head surgeon, Dr. Louise M’Ilroy, stated that she never failed to find a projectile searched for. This was indeed a tribute to the accurate localisation in the X-ray department. Another valuable branch of Miss Stoney’s work was the taking of stereoscopic skiagrams. Miss Stoney took one of the very early skiagrams of gas bubbles in the tissues, due to gas gangrene, a development which has since come into great prominence.
