Yes, he might well be certain of his success!

And yet the joy of the discovery was clouded.  How often had he dreamed of the manifold effects that would be produced by the elixir!  At such moments the hope had sprung up within him that it would possess the power to enlighten him concerning his own nature and existence; would enable him to pierce the veil that hides the mystery of the future from mortal eyes; that it would reveal to the mind of man the true nature of things, and solve the problem of life.

Yet all the questions directed to that end, which he asked himself, remained unanswered, and for this reason he was desirous of seeing whether the essence might not perhaps enable others to grasp the real nature of that which until then had been unfathomable by man.

Consequently he could not resist the temptation, of letting Frau Schimmel inhale the elixir.  Then he asked her why every one who was born was destined to die, and disappear?

To which she only answered:  “Such things you must ask of the good God, who has so willed it.”

When he wished further to know how, and of what ingredients the human blood was made, the old lady laughed, and replied lightly that it was red, and more than that she had not learned from the “Schoolmaster with the Children,” from which she had acquired all that she knew.

Then the doctor cried:  “And so my hard-earned discovery is of less value than I hoped!”

But these words had scarcely escaped him before he smiled to himself, for it was the elixir that had forced him to this outbreak, otherwise he would never have confessed to any one, be he who he might, that his wonderful discovery was in any way incomplete.

Being satisfied with his experiences for that day he no longer hindered the old lady from going to rest.

On his own bed he lay and pondered over the limitations of his discovery.

To reveal the truth, wholly and absolutely, was not within the power of the elixir, nor unfortunately did it possess the efficacy to lead one to a perfect knowledge of oneself; on the other hand it was capable of forcing any one who used it to be absolutely honest in his dealings with his neighbours, and that surely was no small gain.  Indeed it was enough to place him among the most famous discoverers in all ages, and to inscribe his name beside those of the noblest benefactors of man in the whole round world.

Sleepless, yet filled with triumphant joy, like a general who has won a glorious victory, he watched through the night.  When Frau Schimmel came to the house on the following morning she found him with the little Zeno between his knees.

Her suspicion was immediately aroused that the father had misused the child in order to try the effect of the elixir upon it, and she stood at the door and listened.

But the little bottle tightly corked peered from the doctor’s breast-pocket and, instead of questioning Zeno, he was talking to him earnestly:
