Astronomy is certainly an alluring science; set an astronomer before a telescope, and an overwhelming attraction draws his soul away through the tube up into heaven, and leaves his body without mundane interests. An astronomer is necessarily a mathematician, and mathematics are the hardest and most petrifying of studies. The "humane letters," as classic studies are called, draw out the human interests, they necessarily carry men among men, but mathematics draw men away from all the interests of their fellows. The last man one expects to find in love, the last man in whose life one looks for a romantic episode, is a mathematician and astronomer. But as even Cæsar nods, so an astronomer may lapse into spooning. The life of Professor Maedler does not contain much of animated interest; but it had its poetic incident. The curious story of his courtship and marriage may be related without indiscretion, now that the old Selenographer is no more. Even the most prosaic of men have their time of poetry. The swan is said to sing only once--just before it dies. The man of business--the stockbroker, the insurance-company manager, the solicitor, banker, the ironmonger, butcher, greengrocer, postman, have all passed through a "moment," as Hegel would call it, when the soul burst through its rind of common-place and vulgar routine, sang its nightingale song, and then was hushed for ever after. It is said that there are certain flowers which take many years coming to the point of bloom, they open, exhale a flood of incense, and in an hour wither. It is so with many. Even the astronomer has his blooming time. Then, after the honeymoon, the flower withers, the song ceases, the sunshine fades, and folds of the fog of common-place settle deeper than before. Ivan Turgenieff, the Russian novelist, says of love, "It is not an emotion, it is a malady, attacking soul and body. It is developed without rule, it cannot be reckoned with, it cannot be overreached. It lays hold of a man, without asking leave, like a fever or the cholera. It seizes on its prey as a falcon on a dove, and carries it, where it wills. There is no equality in love. The so-termed free inclination of souls towards each other is an idle dream of German professors, who have never loved. No! of two who love, one is the slave, the other is the lord, and not inaccurately have the poets told of the chains of love." But love when it does lay hold of a man assumes some features congruent to his natural habit. It is hardly tempestuous in a phlegmatic temperament, nor is a man of sanguine nature liable to be much influenced by calculations of material advantages. That calculations should form a constituent portion of the multiform web of a mathematician's passion is what we might anticipate.
