'Now, sir,' said the inventor. 'Or perhaps your nerve has failed you?'

Challenger visibly braced himself. Then, pushing my protesting hand to one side, he seated himself upon the chair. The handle clicked into number three. He was gone.

I should have been horrified but for the perfect coolness of the operator. 'It is an interesting process, is it not?' he remarked. 'When one considers the tremendous individuality of the Professor it is strange to think that he is at present a molecular cloud suspended in some portion of this building. He is now, of course, entirely at my mercy. If I choose to leave him in suspension there is nothing on earth to prevent me.'

'I would very soon find means to prevent you.'

The smile once again became a snarl. 'You cannot imagine that such a thought ever entered my mind. Good heavens! Think of the permanent dissolution of the great Professor Challenger vanished into cosmic space and left no trace! Terrible! Terrible! At the same time he has not been as courteous as he might. Don't you think some small lesson – ?'

'No, I do not.'

'Well, we will call it a curious demonstration. Something that would make an interesting paragraph in your paper. For example, I have discovered that the hair of the body being on an entirely different vibration to the living organic tissues can be included or excluded at will. It would interest me to see the bear without his bristles. Behold him!'

There was the click of the lever. An instant later Challenger was seated upon the chair once more. But what a Challenger! What a shorn lion! Furious as I was at the trick that had been played upon him I could hardly keep from roaring with laughter.

His huge head was as bald as a baby's and his chin was as smooth as a girl's. Bereft of his glorious mane the lower part of his face was heavily jowled and ham-shaped, while his whole appearance was that of an old fighting gladiator, battered and bulging, with the jaws of a bulldog over a massive chin.
