"I am glad TO have arrived, sir," said Jane gravely, almost expecting to hear the duchess's delighted "Ha, ha!" from the wings. The little comedy was progressing. Then suddenly she became aware that during the last few minutes Dr. Mackenzie's mind had been concentrated upon something else. She had not filled it at all. The next moment it was turned upon her and two swift turquoise gleams from under the shaggy brows swept over her, with the rapidity and brightness of search-lights. Dr. Mackenzie commenced speaking quickly, with a wonderful rolling of r's. "I understand, Miss Gray, you have come to minister to the patient's mind rather than to his body. You need not trouble to explain. I have it from Sir Deryck Brand, who prescribed a nurse-companion for the patient, and engaged you. I fully agreed with his prescription; and, allow me to say, I admire its ingredients." Jane bowed, and realised how the duchess would be chuckling. What an insufferable little person! Jane had time to think this, while he walked across to the table-cloth, bent over it, and examined an ancient spot of ink. Finding a drop of candle grease near it, he removed it with his thumb nail; brought it carefully to the fire, and laid it on the coals. He watched it melt, fizzle, and flare, with an intense concentration of interest; then jumped round on Jane, and caught her look of fury. "And I think there remains very little for me to say to you about the treatment, Miss Gray," he finished calmly. "You will have received minute instructions from Sir Deryck himself. The great thing now is to help the patient to take an interest in the outer world. The temptation to persons who suddenly become totally blind, is to form a habit of living entirely in a world within; a world of recollection, retrospection, and imagination; the only world, in fact, in which they can see." Jane made a quick movement of appreciation and interest. After all she might learn something useful from this eccentric little Scotchman. Oh to keep his attention off rubbish on the carpet, and grease spots on the table-cloth! "Yes?" she said. "Do tell me more."
