'One of them, I forget which,' said Mark quickly, wishing he had cut the quotations out.

'That ægritudo, now, "ægritudo superveniens," you know—how do you understand that?'

Mark had never troubled himself to understand it at all, so he stared at his interrogator in rather a lost way.

'I mean, do you take it as of the mind or body (that's what made me fancy it must be later Latin). And then there's the correxit?'

Mark admitted that there was the 'correxit.' 'It's mind,' he said quickly. 'Oh, decidedly the mind, not body, and—er—I think that's my 'bus passing. I'll say good-bye;' and he escaped with a weary conviction that he must devote yet more study to the detested 'Illusion.'

This is only a sample of the petty vexations to which he had exposed himself. He had taken over a business which he did not understand, and naturally found the technicalities troublesome, for though, as has been seen, his own tendencies were literary, he had not soared so high as a philosophical romance, while his scholarship, more brilliant than profound, was not always equal to the 'unseen passages' from out-of-the-way authors with which Holroyd had embellished his chapters.

But a little more care made him feel easier on this score, and then there were many compensations; for one unexpected piece of good fortune, which will be recorded presently, he had mainly to thank his friend's book.

He had met an old acquaintance of his, a certain young Herbert Featherstone, who had on any previous chance encounter seemed affected by a kind of trance, during which his eyes lost all power of vision, but was now completely recovered, so much so indeed as to greet Mark with a quite unexpected warmth.

Was it true that he had written this new book? What was its name—'Delusion' or something? Fellows were saying he had; hadn't read it himself; his mother and sister had; said it was a devilish good book, too. Where was he hanging out now, and what was he doing on the 10th? Could he come to a little dance his people had that night? Very well, then, he should have a card.

Mark was slightly inclined to let the other understand that he knew the worth of this resuscitated friendliness, but he refrained. He knew of the Featherstones as wealthy people, with the reputation of giving the pleasantest entertainments in London. He had his way to make in the world, and could not afford, he thought, to neglect these opportunities. So he went to the dance and, as he happened to dance well, enjoyed himself, in spite of the fact that two of his partners had read 'Illusion,' and knew him as the author of it. They were both pretty and charming girls, but Mark did not enjoy either of those particular valses. In the course of the evening he had a brief conversation with his hostess, and was fortunate enough to produce a favourable impression. Mrs. Featherstone was literary herself, as a reputedly strong-minded lady who had once written two particularly weak-minded novels would necessarily be. She liked to have a few rising young literary men in her train, with whom she might discuss subjects loftier than ordinary society cares to grasp; but she was careful at the same time that her daughter should not share too frequently in these intellectual privileges, for Gilda Featherstone was very handsome, and literary men are as impressionable as other people.
