Abstract
IN my Parsons Memorial Lecture delivered before the Physical Society on October 15, 1943, and published in NATURE of December 10, I said that "Metal searchlight mirrors, though occasionally revived, are now almost obsolete, at any rate in Great Britain, owing to the inferiority of reflecting power and the difficulty of maintaining it good under service conditions"; this statement was in accordance with what I had been able to find in print, and with what I had been able to learn personally concerning military searchlights. A certain type of metallic mirror had, in fact, been recently discarded from the service.
