Dr. Grantham's hand still moved on the rheostat handle and as the thin whine from the cabinet came louder they saw that the disk was but a mere ghost-like shape against the sunlight, and then that too had vanished. The paper-weight was invisible! They gazed silently, fascinated, and then as Grantham moved back the control in his hand the shadowy circle of the disk appeared again, it grew quickly more opaque, and as the switch clicked and the cabinet's whine ceased it rested there as black and opaque and visible as ever!
Dr. Grantham leaned and grasped it, handed it to the four. Wonderingly they passed it from hand to hand, seeing it the same as before, quite black and commonplace and visible. Carton, himself oddly stirred by what he had seen, heard Burns' exclamation from beside him.
"Good Lord! What a story!"
"And you can do that to anything?" Carton demanded of the physicist.
The Invisible Man
Dr. Grantham nodded. "To any matter. Gray and I are now finishing a cabinet-projector that will be of sufficient power to make invisible itself and all for a few feet around it. With it a man would be perfectly invisible."
"An invisible man?" President Ellsworth was looking at the scientist keenly. "My dear Grantham—do you mean it would make a man as invisible as that paper-weight?"
The physicist calmly nodded. "Just that, and if he had the cabinet and its compact batteries attached to him he could move at will invisibly."
