Arthur laughed heartily.

'I confess I like that story much better than the others. The _Primum Ens Melissae_ at least offers a less puerile benefit than most magical secrets.'

'Do you call the search for gold puerile?' asked Haddo, who had been sitting for a long time in complete silence.

'I venture to call it sordid.'

'You are very superior.'

'Because I think the aims of mystical persons invariably gross or trivial? To my plain mind, it is inane to raise the dead in order to hear from their phantom lips nothing but commonplaces. And I really cannot see that the alchemist who spent his life in the attempted manufacture of gold was a more respectable object than the outside jobber of modern civilization.'

'But if he sought for gold it was for the power it gave him, and it was power he aimed at when he brooded night and day over dim secrets. Power was the subject of all his dreams, but not a paltry, limited dominion over this or that; power over the whole world, power over all created things, power over the very elements, power over God Himself. His lust was so vast that he could not rest till the stars in their courses were obedient to his will.'

For once Haddo lost his enigmatic manner. It was plain now that his words intoxicated him, and his face assumed a new, a strange, expression. A peculiar arrogance flashed in his shining eyes.

'And what else is it that men seek in life but power? If they want money, it is but for the power that attends it, and it is power again that they strive for in all the knowledge they acquire. Fools and sots aim at happiness, but men aim only at power. The magus, the sorcerer, the alchemist, are seized with fascination of the unknown; and they desire a greatness that is inaccessible to mankind. They think by the science they study so patiently, but endurance and strength, by force of will and by imagination, for these are the great weapons of the magician, they may achieve at last a power with which they can face the God of Heaven Himself.'

Oliver Haddo lifted his huge bulk from the low chair in which he had been sitting. He began to walk up and down the studio. It was curious to see this heavy man, whose seriousness was always problematical, caught up by a curious excitement.

'You've been talking of Paracelsus,' he said. 'There is one of his experiments which the doctor has withheld from you. You will find it neither mean nor mercenary, but it is very terrible. I do not know whether the account of it is true, but it would be of extraordinary interest to test it for oneself.'

He looked round at the four persons who watched him intently. There was a singular agitation in his manner, as though the thing of which he spoke was very near his heart.

'The old alchemists believed in the possibility of spontaneous generation. By the combination of psychical powers and of strange essences, they claim to have created forms in which life became manifest. Of these, the most marvellous were those strange beings, male and female, which were called _homunculi_. The old philosophers doubted the possibility of this operation, but Paracelsus asserts positively that it can be done. I picked up once for a song on a barrow at London Bridge a little book in German. It was dirty and thumbed, many of the pages were torn, and the binding scarcely held the leaves together. It was called _Die Sphinx_ and was edited by a certain Dr Emil Besetzny. It contained the most extraordinary account I have ever read of certain spirits generated by Johann-Ferdinand, Count von Kьffstein, in the Tyrol, in 1775. The sources from which this account is taken consist of masonic manuscripts, but more especially of a diary kept by a certain James Kammerer, who acted in the capacity of butler and famulus to the Count. The evidence is ten times stronger than any upon which men believe the articles of their religion. If it related to less wonderful subjects, you would not hesitate to believe implicitly every word you read. There were ten _homunculi_--James Kammerer calls them prophesying spirits--kept in strong bottles, such as are used to preserve fruit, and these were filled with water. They were made in five weeks, by the Count von Kьffstein and an Italian mystic and rosicrucian, the Abbй Geloni. The bottles were closed with a magic seal. The spirits were about a span long, and the Count was anxious that they should grow. They were therefore buried under two cartloads of manure, and the pile daily sprinkled with a certain liquor prepared with great trouble by the adepts. The pile after such sprinklings began to ferment and steam, as if heated by a subterranean fire. When the bottles were removed, it was found that the spirits had grown to about a span and a half each; the male _homunculi_ were come into possession of heavy beards, and the nails of the fingers had grown. In two of the bottles there was nothing to be seen save clear water, but when the Abbй knocked thrice at the seal upon the mouth, uttering at the same time certain Hebrew words, the water turned a mysterious colour, and the spirits showed their faces, very small at first, but growing in size till they attained that of a human countenance. And this countenance was horrible and fiendish.'

Haddo spoke in a low voice that was hardly steady, and it was plain that he was much moved. It appeared as if his story affected him so that he could scarcely preserve his composure. He went on.

'These beings were fed every three days by the Count with a rose-coloured substance which was kept in a silver box. Once a week the bottles were emptied and filled again with pure rain-water. The change had to be made rapidly, because while the _homunculi_ were exposed to the air they closed their eyes and seemed to grow weak and unconscious, as though they were about to die. But with the spirits that were invisible, at certain intervals blood was poured into the water; and it disappeared at once, inexplicably, without colouring or troubling it. By some accident one of the bottles fell one day and was broken. The _homunculus_ within died after a few painful respirations in spite of all efforts to save him, and the body was buried in the garden. An attempt to generate another, made by the Count without the assistance of the Abbй, who had left, failed; it produced only a small thing like a leech, which had little vitality and soon died.'

Haddo ceased speaking, and Arthur looked at him with amazement. 'But taking for granted that the thing is possible, what on earth is the use of manufacturing these strange beasts?' he exclaimed.

'Use!' cried Haddo passionately. 'What do you think would be man's sensations when he had solved the great mystery of existence, when he saw living before him the substance which was dead? These _homunculi_ were seen by historical persons, by Count Max Lemberg, by Count Franz-Josef von Thun, and by many others. I have no doubt that they were actually generated. But with our modern appliances, with our greater skill, what might it not be possible to do now if we had the courage? There are chemists toiling away in their laboratories to create the primitive protoplasm from matter which is dead, the organic from the inorganic. I have studied their experiments. I know all that they know. Why shouldn't one work on a larger scale, joining to the knowledge of the old adepts the scientific discovery of the moderns? I don't know what would be the result. It might be very strange and very wonderful. Sometimes my mind is verily haunted by the desire to see a lifeless substance move under my spells, by the desire to be as God.'

He gave a low weird laugh, half cruel, half voluptuous. It made Margaret shudder with sudden fright. He had thrown himself down in the chair, and he sat in complete shadow. By a singular effect his eyes appeared blood-red, and they stared into space, strangely parallel, with an intensity that was terrifying. Arthur started a little and gave him a searching glance. The laugh and that uncanny glance, the unaccountable emotion, were extraordinarily significant. The whole thing was explained if Oliver Haddo was mad.
