FROM time to time the British Medical Bulletin publishes articles by experts on the development of medical studies in Britain. The first of these, on the development of ophthalmology (Brit. Med. Bull., 1, 100; 1943), was noticed in Nature (153, 383, March 25, 1944). The second, third and fourth have now appeared (Brit. Med. Bull., 2, Nos. 5–6; 1944). The second is on the genetic aspect of disease, by Dr. Julia Bell; the third is on obstetrics, by Prof. James Young, of the British Postgraduate Medical School, London; the fourth is on oto-laryngology, by Dr. Douglas Guthrie.
