NEW ANAESTHETIC.
discovery by doctors. POWERFUL LOCAL EFFECT. LONDON, March 19. As a result of self-experiments extending over four months, two London doctors have discovered a new local anaesthetic called percain, which they claim to be the most powerful known. The discoverers, Dr. Jennings Marshall and Dr. Norman Lake, both of Charing Cross Hospital, say that percain marks a definite advance over existing local anaesthetic substances, particularly for spinal anaesthesia. Skin injections produced immediate and complete insensitivity lasting for two hours and a half, and deeper injections in five minutes produced anaesthesia lasting for three hours and a half.
