been marriages of financial convenience, essentially arranged marriages. Specifically, when they were younger, Eduard was married off to a rich older woman through the workings and insatiable greed of his father; Charlotte, likewise, when her prospects were none the best, was compelled or obliged to marry a wealthy man, whom she did not love. In the fourth chapter, the characters detail the world's first ever verbally-depicted human double displacement chemical reaction. The chapter begins with description of the affinity map (reaction map) or 'topographical chart' as Goethe calls it. On this reaction map, we are told that on it 'the features of the estate and its surroundings were clearly depicted, on quite a large scale, in pen and in different colors, to which the Captain had give a firm basis by taking trigonometrical measurements'. Next, to explain the reaction, we are told: 'provided it does not seem pedantic,' the Captain said, 'I think I can briefly sum up in the language of signs. Imagine an A intimately united with a B, so that no force is able to sunder them; imagine a C likewise related to a D; now bring the two couples into contact: A will throw itself at D, C at B, without our being able to say which first deserted its partner, which first embraced the other's partner.' This is shown below: AB + CD → AD + BC 'Now then!' Eduard interposed: 'until we see all this with our own eyes, let us look on this formula as a metaphor from which we may extract a lesson we can apply immediately to ourselves. You, Charlotte, represent the A, and I represent your B; for in fact I do depend altogether on you and follow you as A is followed by B. The C is quite obviously the Captain, who for the moment is to some extent drawing me away from you. Now it is only fair that, if you are not to vanish into the limitless air, you must be provided with a D, and this D is unquestionably the charming little lady Ottilie, whose approaching presence you may no longer resist.'
