On the morning of the day upon which they had asked him to tea, Oliver Haddo left at Margaret's door vast masses of chrysanthemums. There were so many that the austere studio was changed in aspect. It gained an ephemeral brightness that Margaret, notwithstanding pieces of silk hung here and there on the walls, had never been able to give it. When Arthur arrived, he was dismayed that the thought had not occurred to him.

'I'm so sorry,' he said. 'You must think me very inconsiderate.'

Margaret smiled and held his hand.

'I think I like you because you don't trouble about the common little attentions of lovers.'

'Margaret's a wise girl,' smiled Susie. 'She knows that when a man sends flowers it is a sign that he has admired more women than one.'

'I don't suppose that these were sent particularly to me.'

Arthur Burdon sat down and observed with pleasure the cheerful fire. The drawn curtains and the lamps gave the place a nice cosiness, and there was the peculiar air of romance which is always in a studio. There is a sense of freedom about it that disposes the mind to diverting speculations. In such an atmosphere it is possible to be serious without pompousness and flippant without inanity.

In the few days of their acquaintance Arthur and Susie had arrived at terms of pleasant familiarity. Susie, from her superior standpoint of an unmarried woman no longer young, used him with the good-natured banter which she affected. To her, he was a foolish young thing in love, and she marvelled that even the cleverest man in that condition could behave like a perfect idiot. But Margaret knew that, if her friend chaffed him, it was because she completely approved of him. As their intimacy increased, Susie learnt to appreciate his solid character. She admired his capacity in dealing with matters that were in his province, and the simplicity with which he left alone those of which he was ignorant. There was no pose in him. She was touched also by an ingenuous candour which gave a persuasive charm to his abruptness. And, though she set a plain woman's value on good looks, his appearance, rough hewn like a statue in porphyry, pleased her singularly. It was an index of his character. The look of him gave you the whole man, strong yet gentle, honest and simple, neither very imaginative nor very brilliant, but immensely reliable and trustworthy to the bottom of his soul. He was seated now with Margaret's terrier on his knees, stroking its ears, and Susie, looking at him, wondered with a little pang why no man like that had even cared for her. It was evident that he would make a perfect companion, and his love, once won, was of the sort that did not alter.

Dr Porho?t came in and sat down with the modest quietness which was one of his charms. He was not a great talker and loved most to listen in silence to the chatter of young people. The dog jumped down from Arthur's knee, went up to the doctor, and rubbed itself in friendly fashion against his legs. They began to talk in the soft light and had forgotten almost that another guest was expected. Margaret hoped fervently that he would not come. She had never looked more lovely than on this afternoon, and she busied herself with the preparations for tea with a housewifely grace that added a peculiar delicacy to her comeliness. The dignity which encompassed the perfection of her beauty was delightfully softened, so that you were reminded of those sweet domestic saints who lighten here and there the passionate records of the Golden Book.

'_C'est tellement intime ici_,' smiled Dr Porho?t, breaking into French in the impossibility of expressing in English the exact feeling which that scene gave him.

It might have been a picture by some master of _genre_. It seemed hardly by chance that the colours arranged themselves in such agreeable tones, or that the lines of the wall and the seated persons achieved such a graceful decoration. The atmosphere was extraordinarily peaceful.

There was a knock at the door, and Arthur got up to open. The terrier followed at his heels. Oliver Haddo entered. Susie watched to see what the dog would do and was by this time not surprised to see a change come over it. With its tail between its legs, the friendly little beast slunk along the wall to the furthermost corner. It turned a suspicious, frightened eye upon Haddo and then hid its head. The visitor, intent upon his greetings, had not noticed even that there was an animal in the room. He accepted with a simple courtesy they hardly expected from him the young woman's thanks for his flowers. His behaviour surprised them. He put aside his poses. He seemed genuinely to admire the cosy little studio. He asked Margaret to show him her sketches and looked at them with unassumed interest. His observations were pointed and showed a certain knowledge of what he spoke about. He described himself as an amateur, that object of a painter's derision: the man 'who knows what he likes'; but his criticism, though generous, showed that he was no fool. The two women were impressed. Putting the sketches aside, he began to talk, of the many places he had seen. It was evident that he sought to please. Susie began to understand how it was that, notwithstanding his affectations, he had acquired so great an influence over the undergraduates of Oxford. There was romance and laughter in his conversation; and though, as Frank Hurrell had said, lacking in wit, he made up for it with a diverting pleasantry that might very well have passed for humour. But Susie, though amused, felt that this was not the purpose for which she had asked him to come. Dr Porho?t had lent her his entertaining work on the old alchemists, and this gave her a chance to bring their conversation to matters on which Haddo was expert. She had read the book with delight and, her mind all aflame with those strange histories wherein fact and fancy were so wonderfully mingled, she was eager to know more. The long toil in which so many had engaged, always to lose their fortunes, often to suffer persecution and torture, interested her no less than the accounts, almost authenticated, of those who had succeeded in their extraordinary quest.

She turned to Dr Porho?t.

'You are a bold man to assert that now and then the old alchemists actually did make gold,' she said.

'I have not gone quite so far as that,' he smiled. 'I assert merely that, if evidence as conclusive were offered of any other historical event, it would be credited beyond doubt. We can disbelieve these circumstantial details only by coming to the conclusion beforehand that it is impossible they should be true.'

'I wish you would write that life of Paracelsus which you suggest in your preface.'

Dr Porho?t, smiling shook his head.

'I don't think I shall ever do that now,' he said. 'Yet he is the most interesting of all the alchemists, for he offers the fascinating problem of an immensely complex character. It is impossible to know to what extent he was a charlatan and to what a man of serious science.'

Susie glanced at Oliver Haddo, who sat in silence, his heavy face in shadow, his eyes fixed steadily on the speaker. The immobility of that vast bulk was peculiar.

'His name is not so ridiculous as later associations have made it seem,' proceeded the doctor, 'for he belonged to the celebrated family of Bombast, and they were called Hohenheim after their ancient residence, which was a castle near Stuttgart in Würtemberg. The most interesting part of his life is that which the absence of documents makes it impossible accurately to describe. He travelled in Germany, Italy, France, the Netherlands, in Denmark, Sweden, and Russia. He went even to India. He was taken prisoner by the Tartars, and brought to the Great Khan, whose son he afterwards accompanied to Constantinople. The mind must be dull indeed that is not thrilled by the thought of this wandering genius traversing the lands of the earth at the most eventful date of the world's history. It was at Constantinople that, according to a certain _aureum vellus_ printed at Rorschach in the sixteenth century, he received the philosopher's stone from Solomon Trismosinus. This person possessed also the _Universal Panacea_, and it is asserted that he was seen still alive by a French traveller at the end of the seventeenth century. Paracelsus then passed through the countries that border the Danube, and so reached Italy, where he served as a surgeon in the imperial army. I see no reason why he should not have been present at the battle of Pavia. He collected information from physicians, surgeons and alchemists; from executioners, barbers, shepherds, Jews, gipsies, midwives, and fortune-tellers; from high and low, from learned and vulgar. In the sketch I have given of his career in that volume you hold, I have copied out a few words of his upon the acquirement of knowledge which affect me with a singular emotion.'

Dr Porho?t took his book from Miss Boyd and opened it thoughtfully. He read out the fine passage from the preface of the _Paragranum_:

'I went in search of my art, often incurring danger of life. I have not been ashamed to learn that which seemed useful to me even from vagabonds, hangmen, and barbers. We know that a lover will go far to meet the woman he adores; how much more will the lover of Wisdom be tempted to go in search of his divine mistress.'

He turned the page to find a few more lines further on:

'We should look for knowledge where we may expect to find it, and why should a man be despised who goes in search of it? Those who remain at home may grow richer and live more comfortably than those who wander; but I desire neither to live comfortably nor to grow rich.'

'By Jove, those are fine words,' said Arthur, rising to his feet.

Their brave simplicity moved him as no rhetoric could have done, and they made him more eager still to devote his own life to the difficult acquisition of knowledge. Dr Porho?t gave him his ironic smile.

'Yet the man who could write that was in many ways a mere buffoon, who praised his wares with the vulgar glibness of a quack. He was vain and ostentatious, intemperate and boastful. Listen:

'After me, O Avicenna, Galen, Rhases and Montagnana! After me, not I after you, ye men of Paris, Montpellier, Meissen, and Cologne; all you that come from the countries along the Danube and the Rhine, and you that come from the islands of the sea. It is not for me to follow you, because mine is the lordship. The time will come when none of you shall remain in his dark corner who will not be an object of contempt to the world, because I shall be the King, and the Monarchy will be mine.'

Dr Porho?t closed the book.

'Did you ever hear such gibberish in your life? Yet he did a bold thing. He wrote in German instead of in Latin, and so, by weakening the old belief in authority, brought about the beginning of free thought in science. He continued to travel from place to place, followed by a crowd of disciples, some times attracted to a wealthy city by hope of gain, sometimes journeying to a petty court at the invitation of a prince. His folly and the malice of his rivals prevented him from remaining anywhere for long. He wrought many wonderful cures. The physicians of Nuremberg denounced him as a quack, a charlatan, and an impostor. To refute them he asked the city council to put under his care patients that had been pronounced incurable. They sent him several cases of elephantiasis, and he cured them: testimonials to that effect may still be found in the archives of Nuremberg. He died as the result of a tavern brawl and was buried at Salzburg. Tradition says that, his astral body having already during physical existence become self-conscious, he is now a living adept, residing with others of his sort in a certain place in Asia. From there he still influences the minds of his followers and at times even appears to them in visible and tangible substance.'

'But look here,' said Arthur, 'didn't Paracelsus, like most of these old fellows, in the course of his researches make any practical discoveries?'

'I prefer those which were not practical,' confessed the doctor, with a smile. 'Consider for example the _Tinctura Physicorum_, which neither Pope nor Emperor could buy with all his wealth. It was one of the greatest alchemical mysteries, and, though mentioned under the name of _The Red Lion_ in many occult works, was actually known to few before Paracelsus, except Hermes Trismegistus and Albertus Magnus. Its preparation was extremely difficult, for the presence was needed of two perfectly harmonious persons whose skill was equal. It was said to be a red ethereal fluid. The least wonderful of its many properties was its power to transmute all inferior metals into gold. There is an old church in the south of Bavaria where the tincture is said to be still buried in the ground. In the year 1698 some of it penetrated through the soil, and the phenomenon was witnessed by many people, who believed it to be a miracle. The church which was thereupon erected is still a well-known place for pilgrimage. Paracelsus concludes his directions for its manufacture with the words: _But if this be incomprehensible to you, remember that only he who desires with his whole heart will find, and to him only who knocks vehemently shall the door be opened_.'

'I shall never try to make it,' smiled Arthur.

'Then there was the _Electrum Magicum_, of which the wise made mirrors wherein they were able to see not only the events of the past and of the present, but the doings of men in daytime and at night. They might see anything that had been written or spoken, and the person who said it, and the causes that made him say it. But I like best the _Primum Ens Melissae_. An elaborate prescription is given for its manufacture. It was a remedy to prolong life, and not only Paracelsus, but his predecessors Galen, Arnold of Villanova, and Raymond Lulli, had laboured studiously to discover it.'

'Will it make me eighteen again?' cried Susie.

'It is guaranteed to do so,' answered Dr Porho?t gravely. 'Lesebren, a physician to Louis XIV, gives an account of certain experiments witnessed by himself. It appears that one of his friends pre............
