Perret saw that his friend was in a bad temper, so did not try to carry on the argument.

"Say," he said, "you ought to make a special note of that case of No. 25, for your thesis. She was in your ward for about six months, wasn't she?"

"No. 25?" said Sembadel. "Yes, I know: a woman named Rambert; age about forty; hallucination that people are persecuting her; anæmic, with alternate crises of excitement and melancholia, punctuated by fits of passion; treatment: rest, nourishment, anodynes."

"You evidently remember the case distinctly."

"She interested me; she has marvellous eyes. Well, what about her?"

"Why, when she was moved into my pavilion the diagnosis was bad and the prognosis very bad: she was supposed to be incurable. Just go and see her now: her brain is restored: she's a new woman." He came to the table and picked up some notepaper. "I wrote to her husband a day or two ago and told him he might expect to hear that his wife had recovered, but I imagine my letter miscarried, for I've had no answer. I have a good mind to write to him again and ask for permission to send her to the convalescent home. The mischief of it is that this Etienne Rambert may want to remove her altogether, and that would mean one paying patient less, which would put our worthy director in a bad temper for a month."

He turned to his correspondence, and for some minutes the silence in the room was only broken by the scratching of pens on paper. Then an attendant came in, bringing a quantity of letters. Perret picked them up and began to sort them out.

"None for you," he said to Sembadel. "Not one of those little mauve envelopes which you look for every day and which decide what your temper will be. I must look out for storms."

"Shan't even have time to grouse to-day," Sembadel growled again. "You forget that Swelding pays us an official visit to-day."

"The Danish professor? Is it this morning that he is coming?"
