Dr. Martin smiled. “These things will happen. Mrs. Carlyle has a thoroughly good constitution; a far stronger one than—than——”

“Than what?” said Mr. Carlyle, wondering why he hesitated.

“You must grant me pardon. I may as well finish, now I have begun; but I was not thinking when I spoke. She is stronger than was Lady Isabel. I must be off to catch the six train.”

“You will come over from time to time to East Lynne to see William?”

“If you wish it. It may be a satisfaction, perhaps. Bon jour, madame.”

Lady Isabel bowed to him as he left the room with Mr. Carlyle. “How fond that French governess of yours is of the boy!” the doctor whispered, as they crossed the hall. “I detected it when she brought him to Lynneborough. And you saw her just now! That emotion was all because he could not live. Good-bye.”

Mr. Carlyle grasped his hand. “Doctor, I wish you could save him!” he passionately uttered.

“Ah, Carlyle! If we humble mites of human doctors could but keep those whom it is the Great Physician’s pleasure to take, how we should be run after! There’s hidden mercy, remember, in the darkest cloud. Farewell my friend.”

Mr. Carlyle returned to the room. He approached Lady Isabel, looking down upon her as she sat; not that he could see much of her face. “These are grievous tidings. But you were more prepared for them, I fancy, than I was.”

She started suddenly up, approached the window, and looked out, as if she saw somebody passing whom she would gaze at. All of emotion was stirred up within her—her temples throbbed, her throat beat, her breath became hysterical. Could she bear thus to hold confidential converse with him over the state of their child? She pulled off her gloves for coolness to her burning hands, she wiped the moisture from her pale forehead, she struggled manfully for calmness. What excuse could she offer to Mr. Carlyle?
