There is a recognized branch of science familiar to all those who know anything of the studies relating to life, under the name of Teratology. It deals with all sorts of monstrosities which are to be met with in living beings, and more especially in animals. It is found that what used to be called lusus naturae, or freaks of nature, are just as much subject to laws as the naturally developed forms of living creatures.

The rustic looks at the Siamese twins, and thinks he is contemplating an unheard-of anomaly; but there are plenty of cases like theirs in the books of scholars, and though they are not quite so common as double cherries, the mechanism of their formation is not a whit more mysterious than that of the twinned fruits. Such cases do not disturb the average arrangement; we have Changs and Engs at one pole, and Cains and Abels at the other. One child is born with six fingers on each hand, and another falls short by one or more fingers of his due allowance; but the glover puts his faith in the great law of averages, and makes his gloves with five fingers apiece, trusting nature for their counterparts.

Thinking people are not going to be scared out of explaining or at least trying to explain things by the shrieks of persons whose beliefs are disturbed thereby. Comets were portents to Increase Mather, President of Harvard College; “preachers of Divine wrath, heralds and messengers of evil tidings to the world.” It is not so very long since Professor Winthrop was teaching at the same institution. I can remember two of his boys very well, old boys, it is true, they were, and one of them wore a three-cornered cocked hat; but the father of these boys, whom, as I say, I can remember, had to defend himself against the minister of the Old South Church for the impiety of trying to account for earthquakes on natural principles. And his ancestor, Governor Winthrop, would probably have shaken his head over his descendant's dangerous audacity, if one may judge by the solemn way in which he mentions poor Mrs. Hutchinson's unpleasant experience, which so grievously disappointed her maternal expectations. But people used always to be terribly frightened by those irregular vital products which we now call “interesting specimens” and carefully preserve in jars of alcohol. It took next to nothing to make a panic; a child was born a few centuries ago with six teeth in its head, and about that time the Turks began gaining great advantages over the Christians. Of course there was an intimate connection between the prodigy and the calamity. So said the wise men of that day.

—All these out-of-the-way cases are studied connectedly now, and are found to obey very exact rules. With a little management one can even manufacture living monstrosities. Malformed salmon and other fish can be supplied in quantity, if anybody happens to want them. Now, what all I have said is tending to is exactly this, namely, that just as the celestial movements are regulated by fixed laws, just as bodily monstrosities are produced according to rule, and with as good reason as normal shapes, so obliquities of character are to be accounted for on perfectly natural principles; they are just as capable of classification as the bodily ones, and they all diverge from a certain average or middle term which is the type of its kind. If life had been a little longer I would have written a number of essays for which, as it is, I cannot expect to have time. I have set down the titles of a hundred or more, and I have often been tempted to publish these, for according to my idea, the title of a book very often renders the rest of it unnecessary. “Moral Teratology,” for instance, which is marked No. 67 on my list of “Essays Potential, not Actual,” suggests sufficiently well what I should be like to say in the pages it would preface. People hold up their hands at a moral monster as if there was no reason for his existence but his own choice. That was a fine specimen we read of in the papers a few years ago, the Frenchman, it may be remembered, who used to waylay and murder young women, and after appropriating their effects, bury their bodies in a private cemetery he kept for that purpose. It is very natural, and I do not say it is not very proper, to hang such eccentric persons as this; but it is not clear whether his vagaries produce any more sensation at Headquarters than the meek enterprises of the mildest of city missionaries. For the study of Moral Teratology will teach you that you do not get such a malformed character as that without a long chain of causes to account for it; and if you only knew those causes, you would know perfectly well what to expect.

You may feel pretty sure that our friend of the private cemetery was not the child of pious and intelligent parents; that he was not nurtured by the best of mothers, and educated by the most judicious teachers; and that he did not come of a lineage long known and honored for its intellectual and moral qualities. Suppose that one should go to the worst quarter of the city and pick out the worst-looking child of the worst couple he could find, and then train him up successively at the School for Infant Rogues, the Academy for Young Scamps, and the College for Complete Criminal Education, would it be reasonable to expect a Francois Xavier or a Henry Martyn to be the result of such a training? The traditionists, in whose presumptuous hands the science of anthropology has been trusted from time immemorial, have insisted on eliminating cause and effect from the domain of morals. When they have come across a moral monster they have seemed to think that he put himself together, having a free choice of all the constituents which make up manhood, and that consequently no punishment could be too bad for him.

I say, hang him and welcome, if that is the best thing for society; hate him, in a certain sense, as you hate a rattlesnake, but, if you pretend to be a philosopher, recognize the fact that what you hate in him is chiefly misfortune, and that if you had been born with his villanous low forehead and poisoned instincts, and bred among creatures of the Races Maudites whose natural history has to be studied like that of beasts of prey and vermin, you would not have been sitting there in your gold-bowed spectacles and passing judgment on the peccadilloes of your fellow-creatures.

I have seen men and women so disinterested and noble, and devoted to the best works, that it appeared to me if any good and faithful servant was entitled to enter into the joys of his Lord, such as these might be. But I do not know that I ever met with a human being who seemed to me to have a stronger claim on the pitying consideration and kindness of his Maker than a wretched, puny, crippled, stunted child that I saw in Newgate, who was pointed out as one of the most notorious and inveterate little thieves in London. I have no doubt that some of those who were looking at this pitiable morbid secretion of the diseased social organism thought they were very virtuous for hating him so heartily.

It is natural, and in one sense is all right enough. I want to catch a thief and put the extinguisher on an incendiary as much as my neighbors do; but I have two sides to my consciousness as I have two sides to my heart, one carrying dark, impure blood, and the other the bright stream which has been purified and vivified by the great source of life and death,—the oxygen of the air which gives all things their vital heat, and burns all things at last to ashes.

One side of me loves and hates; the other side of me judges, say rather pleads and suspends judgment. I think, if I were left to myself, I should hang a rogue and then write his apology and subscribe to a neat monument, commemorating, not his virtues, but his misfortunes. I should, perhaps, adorn the marble with emblems, as is the custom with regard to the more regular and normally constituted members of society. It would not be proper to put the image of a lamb upon the stone which marked the resting-place of him of the private cemetery. But I would not hesitate to place the effigy of a wolf or a hyena upon the monument. I do not judge these animals, I only kill them or shut them up. I presume they stand just as well with their Maker as lambs and kids, and the existence of such beings is a perpetual plea for God Almighty's poor, yelling, scalping Indians, his weasand-stopping Thugs, his despised felons, his murdering miscreants, and all the unfortunates whom we, picked individuals of a picked class of a picked race, scrubbed, combed, and catechized from our cradles upward, undertake to find accommodations for in another state of being where it is to be hoped they will have a better chance than they had in this.

The Master paused, and took off his great round spectacles. I could not help thinking that he looked benevolent enough to pardon Judas Iscariot just at that moment, though his features can knot themselves up pretty, formidably on occasion.
