"Do you call my father a man of the world?" Lucy asked, surprised and pleased.

"Assuredly."

"Of this world, or the other?"

Mona raised her eyes slowly. "Looked at from your father's point of view, it is a little difficult to say where this world ends and the other begins. He would tell you that this is the other world, and the other world w this."

"No, indeed, he would not. Father never gets on to the eternals with me."

This was rather a sore point with Lucy, so she hastened on, "Do you know, your aunt's 'At Home' is going to be no end of an affair?"

"Is it?"

"Yes; I am in a state of wild excitement. Father is giving me a new gown."

"I am frivolling shamefully this week," Mona said. "I have promised to go to the Bernards' at Surbiton from Saturday to Monday. I don't think I ought to go to my aunt's as well."

"Tell Sir Douglas that! By the way, while you are here, you might cast your eagle eye through that microscope, and tell me what the slide is. I forgot to label it at the time, and now I can't spot it."
