"Forgive me," said Charlotte, "as I forgive the natural philosopher. I cannot see any choice in this; I see a natural necessity rather, and scarcely that. After all, it is perhaps merely a case of opportunity. Opportunity makes relations as it makes thieves; and as long as the talk is only of natural substances, the choice to me appears to be altogether in the hands of the chemist who brings the creatures together. Once, however, let them be brought together, and then God have mercy on them. In the present case, I cannot help being sorry for the poor acid gas, which is driven out up and down infinity again."
"The acid's business," answered the Captain, "is now to get connected with water, and so serve as a mineral fountain for the refreshing of sound or disordered mankind."
"That is very well for the gypsum to say," said Charlotte. "The gypsum is all right, is a body, is provided for. The other poor, desolate creature may have trouble enough to go through before it can find a second home for itself."
"I am much mistaken," said Edward, smiling, "if there be not some little _arrière pensée_ behind this. Confess your wickedness! You mean me by your lime; the lime is laid hold of by the Captain, in the form of sulphuric acid, torn away from your agreeable society, and metamorphosed into a refractory gypsum."
"If your conscience prompts you to make such a reflection," replied Charlotte, "I certainly need not distress myself. These comparisons are pleasant and entertaining; and who is there that does not like playing with analogies? But man is raised very many steps above these elements; and if he has been somewhat liberal with such fine words as Election and Elective Affinities, he will do well to turn back again into himself, and take the opportunity of considering carefully the value and meaning of such expressions. Unhappily, we know cases enough where a connection apparently indissoluble between two persons, has, by the accidental introduction of a third, been utterly destroyed, and one or the other of the once happily united pair been driven out into the wilderness."
"Then you see how much more gallant the chemists are," said Edward. "They at once add a fourth, that neither may go away empty."
