ABSTRACT THERE were many difficulties to encounter in entering the room just now. To begin with, we had to bear the crushing load of the atmosphere, amounting to 14 lb. on every square inch.
At each step forwards it was necessary to tread gingerly on a piece of ground moving at the rate of twenty miles a second on its way round the sun. We were poised precariously on a globe,
apparently hanging by our feet, head outwards into space. And this acrobatic feat was performed in,the face of a tremendous wind of aether, blowing at I do not know how many miles a second
literally through us. We do not claim much credit for overcoming these difficulties—because we never noticed them. But I venture to remind you of them, because I am about to speak of some
other extraordinary things that may be happening to us of which we are quite, unconscious. Access through your institution Buy or subscribe This is a preview of subscription content, access
