Tadini no doubt interpreted my silence as a mark of disapproval of the German’s laughter, and thought to better matters by asking me to give my opinion.

“As you want to hear it,” said I, “here it is.”

“There’s a great difference between a tooth and the crystalline humour; and though you may have succeeded in putting an artificial tooth into a gum, this treatment will not do with the eye.”

“Sir, I am not a dentist.”

“No, nor an oculist either.”

At this the ignorant rascal got up and left the room, and it was decidedly the best thing he could do.

We laughed over this new treatment, and the lady promised to have nothing more to do with him.  The professor was not content to despise his opponent in silence.  He had him cited before the Faculty of Medicine to be examined on his knowledge of the eye, and procured the insertion of a satiric article in the news on the new operation for replacing the crystalline humour, alluding to the wonderful artist then in Warsaw who could perform this operation as easily as a dentist could put in a false tooth.

This made Tadini furious, and he set upon the old professor in the street and forced him to the refuge in a house.

After this he no doubt left the town on foot, for he was seen no more.  Now the reader is in a position to understand my surprise and amusement, when, one day as I peered through the grating in my dungeon, I saw the oculist Tadini standing over me with gun in hand.  But he at all events evinced no amusement whatever, while I roared and roared again with laughter for the two hours his duty lasted.

I gave him a good meal and a sufficiency of my excellent wine, and at the end a crown, promising that he should have the same treatment every time he returned to the post.  But I only saw him four times, as the guard at my cell was a position eagerly coveted and intrigued for by the other soldiers.

He amused me by the story of his misadventures since he had left Warsaw.  He had travelled far and wide without making a fortune, and at last arrived in Barcelona, where he failed to meet with any courtesy or consideration.  He had no introduction, no diploma; he had refused to submit to an examination in the Latin tongue, because (as he said) there was no connection between the learned languages and the diseases of the eye; and the result was that, instead of the common fate of being ordered to leave the country, he was made into a soldier.  He told me in confidence that he intended to desert, but he said he should take care to avoid the galleys.

“What have you done with your crystals?”

“I have renounced them since I left Warsaw, though I am sure they would succeed.”

I never heard of him again.

On December 28th, six weeks after my arrest, the officer of the guard came to my cell and told me to dress and follow him.

“Where are we going?”
