"No," said the doctor quietly. "You are here, at my house."
"Of course; and that was Mrs. Cameron who went out to get the oil, and—"
He stopped short, and looked about him for some moments. Then in a puzzled way:—
"There's something I want to think about, but I can't."
"Don't worry about it, then. Lie still till you can."
"Yes, that will be the best way. Ah! here she is."
Mrs. Cameron was back with the oil, and he made her lips quiver, and she had hard work to keep back her tears, as he said,—
"That's good of you to fetch it. Thank you, Doctor. What was it bit me? One of those big mosquitoes? Ah!"
He uttered a wild cry, and his face grew convulsed with horror.
"What is it, my dear boy?" said the doctor.
