plans of structure or structural ideas.
What now are classes? Are they lesser divisions, differing only in extent, or are they founded on special characters? I believe the latter view to be the true one, and that class characters have a significance quite different from that of their mere range or extent. These divisions are founded on certain categories of structure; and were there but one animal of a class in the world, if it had those characters on which a class is founded, it would be as distinct from all other animals as if its kind were counted by thousands. Baer approached the idea of the classes when he discriminated between plan of structure or type and the degree of perfection in the structure. But while he understands the distinction between a plan and its execution, his ideas respecting the different features of structure are not quite so precise. He does not, for instance, distinguish between the complication of a given structure and the mode of execution of a plan, both of which are combined in what he calls degrees of perfection. And yet, without this distinction, the difference between classes and orders cannot be understood; for classes and orders rest upon a just appreciation of these two categories, which are quite distinct from each other, and have by no means the same significance. Again, quite distinct from both of these is the character of form, not to be confounded either with complication of structure, on which orders are based, or with the execution of the plan, on which classes rest. An example will show that form is no guide for the determination of classes or orders. Take, for instance, a Beche-de-Mer, a member of the highest class of Radiates, and compare it with a Worm. They are both long cylindrical bodies; but one has parallel divisions along the length of the body, the other has the body divided by transverse rings. Though in external form they resemble each other, the one is a worm-like Radiate, the other is a worm-like Articulate, each having the structure of its own type; so that they do not even belong to the same great division of the animal kingdom, much less to the same class. We have a similar instance in the Whales and Fishes,—the Whales having been for a long time considered as Fishes, on account of their form, while their structural complication shows them to be a low order of the class of Mammalia, to which we ourselves belong, that class being founded upon a particular mode of execution of the plan characteristic of the Vertebrates, while the order to which the Whales belong depends upon their complication of structure, as compared with other members of the same class. We may therefore say that neither form nor complication of structure distinguishes classes, but simply the mode of execution of a plan. In Vertebrates, for instance, how do we distinguish the class of Mammalia from the other classes of the type? By the peculiar development of the brain, by their breathing through lungs, by their double circulation, by their bringing forth living young and nursing them with milk. In this class the beasts of prey form a distinct order, superior to the Whales or the herbivorous animals, on account of the higher complication of their structure; and for the same reason we place the Monkeys above them all. But among the beasts of prey we distinguish the Bears, as a family, from the family of Dogs, Wolves, and Cats, on account of their different form, which does not imply a difference either in the complication of their structure or in the mode of execution of their plan.
AGNES OF SORRENTO
CHAPTER XVIII.
THE PENANCE
The course of our story requires us to return to the Capuchin convent, and to the struggles and trials of its Superior; for in his hands is the irresistible authority which must direct the future life of Agnes.
From no guilty compliances, no heedless running into temptation, had he come to love her. The temptation had met him in the direct path of duty; the poison had been breathed in with the perfume of sweetest and most life-giving flowers: nor could he shun that temptation, nor cease to inhale that fatal sweetness, without confessing himself vanquished in a point where, in his view, to yield was to be lost. The subtle and deceitful visit of Father Johannes to his cell had the effect of thoroughly rousing him to a complete sense of his position, and making him feel the immediate, absolute necessity of bringing all the energy of his will, all the resources of his nature to bear on its present difficulties. For he felt, by a fine intuition, that already he was watched and suspected;—any faltering step now, any wavering, any change in his mode of treating his female penitents, would be maliciously noted. The military education of his early days had still left in his mind a strong residuum of personal courage and honor, which made him regard it as dastardly to flee when he ought to conquer, and therefore he set his face as a flint for victory.
But reviewing his interior world, and taking a survey of the work before him, he felt that sense of a divided personality which often becomes so vivid in the history of individuals of strong will and passion. It seemed to him that there were two men within him: the one turbulent, passionate, demented; the other vainly endeavoring by authority, reason, and conscience to bring the rebel to subjection. The discipline of conventual life, the extraordinary austerities to which he had condemned himself, the monotonous solitude of his existence, all tended to exalt the vivacity of the nervous system, which, in the Italian constitution, is at all times disproportionately developed; and when those weird harp-strings of the nerves are once thoroughly unstrung, the fury and tempest of the discord sometimes utterly bewilders the most practised self-government.
But he felt that something must be done with himself, and done immediately; for in a few days he must again meet Agnes at the confessional. He must meet her, not with weak tremblings and passionate fears, but calm as Fate, inexorable as the Judgment-Day. He must hear her confession, not as man, but as God; he must pronounce his judgments with a divine dispassionateness. He must dive into the recesses of her secret heart, and, following with subtile analysis all the fine courses of those fibres which were feeling their blind way towards an earthly love, must tear them remorselessly away. Well could he warn her of the insidiousness of earthly affections; better than any one else he could show her how a name that was blended with her prayers and borne before the sacred shrine in her most retired and solemn hours might at last come to fill all her heart with a presence too dangerously dear. He must direct her gaze up those mystical heights where an unearthly marriage awaited her, its sealed and spiritual bride; he must hurry her footsteps onward to the irrevocable issue.
All this was before him. But ere it could be done, he must subdue himself,—he must become calm and pulseless, in deadly resolve; and what prayer, what penance might avail for this? If all that he had already tried had so miserably failed, what hope? He resolved to quit for a season all human society, and enter upon one of those desolate periods of retreat from earthly converse well known in the annals of saintship as most prolific in spiritual victories.
Accordingly, on the day after the conversation with Father Johannes, he startled the monks by announcing to them that he was going to leave them for several days.
“My brothers,” he said, “the weight of a fearful penance is laid upon me, which I must work out alone. I leave you today, and charge you not to seek to follow my footsteps; but, as you hope to escape hell, watch and wrestle for me and yourselves during the time I am gone. Before many days I hope to return to you with renewed spiritual strength.”
That evening, while Agnes and her uncle were sitting together in their orange-garden, mingling their parting prayers and hymns, scenes of a very different description surrounded the Father Francesco.
One who looks on the flowery fields and blue seas of this enchanting region thinks that the Isles of the Blest could scarcely find on earth a more fitting image; nor can he realize, till experience proves it to him, that he is in the immediate vicinity of a weird and dreary region which might represent no less the goblin horrors of the damned.
Around the foot of Vesuvius lie fair villages and villas garlanded with roses and flushing with grapes whose juice gains warmth from the breathing of its subterraneous fires, while just above them rises a region more awful than can be created by the action of any common causes of sterility. There, immense tracts sloping gradually upward show a desolation so peculiar, so utterly unlike every common solitude of Nature, that one enters upon it with the shudder we give at that which is wholly unnatural. On all sides are gigantic
