Charlotte's tact, in whatever circle she might be, large or small, was remarkable, and she was able to set aside disagreeable or excited expressions without appearing to notice them. When a conversation grew tedious, she knew how to interrupt it; when it halted, she could set it going. And this time her good gift did not forsake her.

"I am sure you will forgive me my fault," she said, when I tell you what it was this moment which came over me. I heard you reading something about Affinities, and I thought directly of some relations of mine, two of whom are just now occupying me a great deal. Then my attention went back to the book. I found it was not about living things at all, and I looked over to get the thread of it right again."

"It was the comparison which led you wrong and confused you," said Edward. "The subject is nothing but earths and minerals. But man is a true Narcissus; he delights to see his own image everywhere; and he spreads himself underneath the universe, like the amalgam behind the glass."

"Quite true," continued the Captain. "That is the way in which he treats everything external to himself. His wisdom and his folly, his will and his caprice, he attributes alike to the animal, the plant, the elements, and the gods."

"Would you," said Charlotte, "if it is not taking you away too much from the immediate subject, tell me briefly what is meant here by Affinities?"

"I shall be very glad indeed," replied the Captain, to whom Charlotte had addressed herself. "That is, I will tell you as well as I can. My ideas on the subject date ten years back; whether the scientific world continues to think the same about it, I cannot tell."

"It is most disagreeable," cried Edward, "that one cannot now-a-days learn a thing once for all, and have done with it. Our forefathers could keep to what they were taught when they were young; but we have, every five years, to make revolutions with them, if we do not wish to drop altogether out of fashion."

"We women need not be so particular," said Charlotte; "and, to speak the truth, I only want to know the meaning of the word. There is nothing more ridiculous in society than to misuse a strange technical word; and I only wish you to tell me in what sense the expression is made use of in connection with these things. What its scientific application is I am quite contented to leave to the learned; who, by-the-by, as far as I have been able to observe, do not find it easy to agree among themselves."

"Whereabouts shall we begin," said Edward, after a pause, to the
Captain, "to come most quickly to the point?"

The latter, after thinking as little while, replied shortly:
