"Not at all," said Hamilton Beamish.

"A doctor couldn't have done it more neatly."

"It's just a knack."

"Why is it," asked the girl, "that, when you get a speck of dust in your eye the size of a pin-point, it seems as big as all out-doors?"

Hamilton Beamish could answer that. The subject was one he had studied.

"The conjunctiva, a layer of mucous membrane which lines the back of the eyelids and is reflected on the front of the globe, this reflection forming the fornix, is extremely sensitive. This is especially so at the point where the tarsal plates of fibrous tissue are attached to the orbital margin by the superior and inferior palpebral ligaments."

"I see," said the girl.

There was a pause.

"Are you calling on Mrs. Waddington?" asked the girl.

"On Miss Waddington."
