She yawned, and this gesture betrayed her.  She turned and looked at him again, calmly, indifferently, as if she scarcely saw him, and then looked out of the window again.

He was upset and dreadfully perplexed, and kept looking at her sideways.

Yes; it was surely his wife.  How could he possibly have doubted it?  There could certainly not be two noses like that, and a thousand recollections flashed through his mind.  He felt the old feeling of the intoxication of love stealing over him, and he called to mind the sweet odor of her skin, her smile when she put her arms on to his shoulders, the soft intonations of her voice, all her graceful, coaxing ways.

But how she had changed and improved!  It was she and yet not she.  She seemed riper, more developed, more of a woman, more seductive, more desirable, adorably desirable.

And this strange, unknown woman, whom he had accidentally met in a railway carriage, belonged to him; he had only to say to her: 

“I insist upon it.”

He had formerly slept in her arms, existed only in her love, and now he had found her again certainly, but so changed that he scarcely knew her.  It was another, and yet it was she herself.  It was some one who had been born and had formed and grown since he had left her.  It was she, indeed; she whom he had loved, but who was now altered, with a more assured smile and greater self-possession.  There were two women in one, mingling a great part of what was new and unknown with many sweet recollections of the past.  There was something singular, disturbing, exciting about it —­a kind of mystery of love in which there floated a delicious confusion.  It was his wife in a new body and in new flesh which lips had never pressed.

And he thought that in a few years nearly every thing changes in us; only the outline can be recognized, and sometimes even that disappears.

The blood, the hair, the skin, all changes and is renewed, and when people have not seen each other for a long time, when they meet they find each other totally different beings, although they are the same and bear the same name.

And the heart also can change.  Ideas may be modified and renewed, so that in forty years of life we may, by gradual and constant transformations, become four or five totally new and different beings.

He dwelt on this thought till it troubled him; it had first taken possession of him when he surprised her in the princess’ room.  He was not the least angry; it was not the same woman that he was looking at —­that thin, excitable little doll of those days.

What was he to do?  How should he address her? and what could he say to her?  Had she recognized him?

The train stopped again.  He got up, bowed, and said:  “Bertha, do you want anything I could bring you?”

She looked at him from head to foot, and answered, without showing the slightest surprise, or confusion, or anger, but with the most perfect indifference:
