Then, finding that he could not control his will, he turned his thoughts to Caffie.

It was only too evident that if he had carried out the idea of strangling Caffie, all the difficulties against which he had struggled, and which would overwhelm him, if not the following day, at least in a few days, would have disappeared immediately.

No more sheriffs, no more creditors. What a deliverance!

Repose, the possibility of passing examinations with a calm spirit that the fever of material troubles would not disturb—in this condition he felt his success was assured.

And his experiments! He would run no danger of seeing them rudely interrupted. His preparations were not cast out-of-doors; his precious culture-tubes were not broken; his vases, his balloons, were not at the second-hand dealer’s. He continued this train of thought to the results that he desired for him, glory; for humanity, the cure of one, and perhaps two, of the most terrible maladies with which it was afflicted.

The question was simple:

On one side, Caffie;

On the other side, humanity and science;

An old rascal who deserved twenty deaths, and who would, anyhow, die naturally in a short time;

And humanity, science, which would profit by a discovery of which he would be the author.
