"My dear Greatrex," he said gently, holding his arm with a kindly pressure, "I should be dealing wrongly with you if I did not candidly tell you that your case gives ground for very serious apprehensions. You are a young man, and with steady attention to curative means and surroundings, it is possible that you may ward off this threatened danger. Society, amusement, relaxation, complete cessation of scientific work, absence, as far as possible, of mental anxiety in any form, may enable you to tide over the turning point. But that there is danger threatened, it would be unkind and untrue not to warn you. It is very unusual for a patient to consult us in person about these matters. More often it is the friends who notice the coming change; but, as you ask me directly for an opinion, I can't help telling you that I regard your case as not without real cause for the strictest care and for a preventive regimen." Arthur thanked him for the numerous directions he gave as to things which should be done or things which should be avoided, and hurried out into the street with his brain swimming and reeling. "Absence of mental anxiety!" he said to himself bitterly. "How calmly they talk about mental anxiety! How can I possibly be free from anxiety when I know I may go mad at any moment, and that the blow would kill Hetty outright? For myself, I should not care a farthing; but for Hetty! It is too terrible." He had not the heart to call at the Aburys' that afternoon, though he had promised to do so; and he tortured himself with the thought that Hetty would think him neglectful. He could not call again while the present suspense lasted; and if his worst fears were confirmed he could never call again, except once, to take leave of Hetty for ever. For, deeply as Arthur Greatrex loved her, he loved her too well ever to dream of marrying her if the possible shadow of madness was to cloud her future life with its perpetual presence. Better she should bear the shock, even if it killed her at once, than that both should live in ceaseless apprehension of that horrible possibility, and should become the parents of children upon whom that hereditary curse might rest for a lifetime, reflecting itself back with the added sting of conscientious remorse on the father who had brought them into the world against his own clear judgment of right and justice. Next morning Arthur went round once more to Professor Linklight's. The professor had promised to read through the paper immediately, and give his opinion of its chances for presentation to the Royal Society. He was sitting at his breakfast-table, in his flowered dressing-gown and slippers, when Arthur called upon him, and, with a cup of coffee in one hand, was actually skimming the last few pages through his critical eyeglass as his visitor entered.
