Tenacity of Odors.
Reading edition
Dr. Carpenter states, in his "Comparative Physiology," that a grain of musk has been kept freely exposed to the air of a room, of which the door and window were constantly open, for ten years, during all which time the air, though constantly changed, was completely impregnated with the odor of musk, and yet at the end of that time the particle was found not to have sensibly diminished in weight.
