The overtasked brain translated its own dangerous condition by anxiety, and the anxiety was not about health, but, as often happens in such instances, about that subject which had most occupied the patient's mind before the approaches of disease—namely, money. With all his riches, Jacob Ogden grew more nervously anxious about money matters than the poorest laborer on his estate. His mind ran incessantly upon possible causes of loss; and as in the best-regulated property such causes are always infinitely numerous, he found them only too easily. The thousands of details which, when in health, he had carried in his head as lightly as we carry the words of a thoroughly mastered language, began to torment him with the apprehension that they might escape his memory; and whereas, in his better days, no fact troubled him except just at the moment when he wanted it, they now importunately intruded upon his mind when they could only disturb and confuse it.
At length, as his disease advanced towards its sure and terrible development, the anxiety, which was the form it had taken, and the mental hurry and worry which accompanied it, arrived at such a pitch that the least delicate and acute observers remarked it in Jacob Ogden's face. His mother earnestly entreated him not to torment himself so much about his affairs, but to take a partner, and allow himself more rest. The advice came too late. The tender cells of the cerebrum were in a state of fevered disturbance, which must now inevitably lead to one of the forms of madness.
It broke out one night at Wenderholme. He toiled till three o'clock in the morning, alone, at his accounts. There was nothing in them which he would not have mastered quite easily when in health, but the condition of his brain had led to many errors, and the attempt to correct these had only increased and multiplied them. He toiled and toiled till his brain could no longer stand the confusion, and he went mad.
First there came a sense of strangeness to every thing about him, and then a wild alarm—a terror such as he had never known! For a few minutes Reason fiercely struggled to keep her seat, and would not be dispossessed. Those minutes were the most fearful the man had ever passed through. He sprang from his place, and paced the room from wall to wall in violent agitation. "I'm very ill," he thought; "I cannot tell what's the matter with me. I believe I'm going to have a fit. No, it isn't that—it isn't that; I know what it is—I know now—I'm going mad!"
No visible external foe can ever be so terrible as the mysterious internal avengers. They come upon us we know not when nor where. They come when the doors are locked, the mansion guarded, and all the household sleeps. They come in their terrible invisibility, like devils taking possession. The strokes of mortal disease are dealt mysteriously within; and who would not rather meet a body of armed savages than invisible apoplexy or paralysis?
For five minutes Ogden wrestled with his invisible enemy. "I will not go mad," he cried aloud—"I will not!"
And a minute afterwards the struggle ceased, and he was another being, mad beyond hope of recovery.
A strange smile came over his face, and he pressed his hand upon his forehead. "I'll dodge them yet," he said; "they aren't as sharp as I am. I'm sharper than the best of them!"
He began to count the money in his purse. It was not much—five pounds eighteen exactly. He counted the sum quite correctly, over and over again; then he looked anxiously about for a place to hide it in. Whilst he was doing this, his mother, who had felt anxious about him all night, and had been unable to sleep, came to his room-door and listened. She heard him walking about and muttering to himself. Then she opened the door and went in.
He concealed his purse cunningly, and placed himself between the intruder and its hiding-place.
