СКАЧАТЬ 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:

      "You must let me make what will seem a wide sweep; we shall be on our subject almost immediately."

      Charlotte settled her work at her side, promising the fullest attention.

      The Captain began:

      "In all natural objects with which we are acquainted, we observe immediately that they have a certain relation to themselves. It may sound ridiculous to be asserting what is obvious to every one; but it is only by coming to a clear understanding together about what we know, that we can advance to what we do not know."

      "I think," interrupted Edward, "we can make the thing more clear to her, and to ourselves, with examples; conceive water, or oil, or quicksilver; among these you will see a certain oneness, a certain connection of their parts; and this oneness is never lost, except through force or some other determining cause. Let the cause cease to operate, and at once the parts unite again."

      "Unquestionably," said Charlotte, "that is plain; rain-drops readily unite and form streams; and when we were children, it was our delight to play with quicksilver, and wonder at the little globules splitting and parting and running into one another."

      "And here," said the Captain, "let me just cursorily mention one remarkable thing—I mean, that the full, complete correlation of parts which the fluid state makes possible, shows itself distinctly and universally in the globular form. The falling water-drop is round; you yourself spoke of the globules of quicksilver; and a drop of melted lead let fall, if it has time to harden before it reaches the ground, is found at the bottom in the shape of a ball."

      "Let me try and see," said Charlotte, "whether I can understand where you are bringing me. As everything has a reference to itself, so it must have some relation to others."

      "And that," interrupted Edward, "will be different according to the natural differences of the things themselves. Sometimes they will meet like friends and old acquaintances; they will come rapidly together, and unite without either having to alter itself at all—as wine mixes with water. Others, again, will remain as strangers side by side, and no amount of mechanical mixing or forcing will succeed in combining them. Oil and water may be shaken up together, and the next moment they are separate again, each by itself."

      "One can almost fancy," said Charlotte, "that in these simple forms one sees people that one is acquainted with; one has met with just such things in the societies amongst which one has lived; and the strangest likenesses of all with these soulless creatures are in the masses in which men stand divided one against the other, in their classes and professions; the nobility and the third estate, for instance, or soldiers and civilians."

      "Then again," replied Edward, "as these are united under common laws and customs, so there are intermediate members in our chemical world which will combine elements that are mutually repulsive."

      "Oil, for instance," said the Captain, "we make combine with water with the help of alkalis–"

      "Do not go on too fast with your lesson," said Charlotte. "Let me see that I keep step with you. Are we not here arrived among the affinities?"

      "Exactly," replied the Captain; "we are on the point of apprehending them in all their power and distinctness; such natures as, when they come in contact, at once lay hold of each other, each mutually affecting the other, we speak of as having an affinity one for the other. With the alkalis and acids, for instance, the affinities are strikingly marked. They are of opposite natures; very likely their being of opposite natures is the secret of their inter-relational effect—each reaches out eagerly for its companion, they lay hold of each other, modify each other's character, and form in connection an entirely new substance. There is lime, you remember, which shows the strongest inclination for all sorts of acids—a distinct desire of combining with them. As soon as our chemical chest arrives, we can show you a number of entertaining experiments which will give you a clearer idea than words, and names, and technical expressions."

      "It appears to me," said Charlotte, "that, if you choose to call these strange creatures of yours related, the relationship is not so much a relationship of blood as of soul or of spirit. It is the way in which we see all really deep friendship arise among men, opposite peculiarities of disposition being what best makes internal union possible. But I will wait to see what you can really show me of these mysterious proceedings; and for the present," she added, turning to Edward, "I will promise not to disturb you any more in your reading. You have taught me enough of what it is about to enable me to attend to it."

      "No, no," replied Edward, "now that you have once stirred the thing, you shall not get off so easily. It is just the most complicated cases which are the most interesting. In these you come first to see the degrees of the affinities, to watch them as their power of attraction is weaker or stronger, nearer or more remote. Affinities begin really to interest only when they bring about separations."

      "What!" cried Charlotte, "is that miserable word, which unhappily we hear so often now-a-days in the world; is that to be found in nature's lessons too?"

      "Most certainly," answered Edward; "the title with which chemists were supposed to be most honorably distinguished was, artists of separation."

      "It is not so any more," replied Charlotte; "and it is well that it is not. It is a higher art, and it is a higher merit, to unite. An artist of union is what we should welcome in every province of the universe. However, as we are on the subject again, give me an instance or two of what you mean."

      "We had better keep," said the Captain, "to the same instances of which we have already been speaking. Thus, what we call limestone is a more or less pure calcareous earth in combination with a delicate acid, which is familiar to us in the form of a gas. Now, if we place a piece of this stone in diluted sulphuric acid, this will take possession of the lime, and appear with it in the form of gypsum, the gaseous acid at the same time going off in vapor. Here is a case of separation; a combination arises, and we believe ourselves now justified in applying to it the words 'Elective Affinity;' it really looks as if one relation had been deliberately chosen in preference to another.

      "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."
