WE regret to record the death of Dr. Dawson F. D. Turner at the age of seventy-one years. He was one of the few medical men who took up the study of X-rays in medical work in the real pioneer days. Unfortunately, he suffered from the rays when their dangerous character was scarcely known, but this did not prevent many years of excellent work on his part. He was head of the X-ray department in the Edinburgh Royal Infirmary for nearly twenty-five years, and during this time contributed original papers on the subject of X-rays and medical electricity. His book on the therapeutics of radium was one of the first, if not the first, published in Great Britain. He was a vice-president of the Röntgen Society, and at one time president of the Royal Scottish Society of Arts.
