At length I was in Regent Street. I felt safe now; the broad pavement, the stream of traffic, the long line of gas-lamps, and the still open shops, enabled me, without fear, a little to slacken my pace. I required this relief. I had been ill for two days, and was worse. I felt chilly and aguish; I was suffering from one of those stupendous headaches which possibly give the sufferer some idea of the action of that iron "cap of silence" with which, during the reign of good King Bomba, so many Neapolitan citizens were made acquainted. I can afford to speak lightly of it now; but I was very ill. I ought to have been in my bed. Nothing but my tremor about mamma would have given me nerve and strength for this excursion. She had that day had a sudden return of the breathlessness and palpitation from which she had suffered so much, and I had succeeded in getting Sir Jacob Lake to come to see her. It was a hurried visit, as his visits always were. He saw her, gave some general directions, wrote a prescription, spoke cheerfully to her, and his manner seemed to say he apprehended nothing. I came with him to the stairs, which we went down together, and in the drawing-room I heard the astounding words that told me mamma could not live many months, and might be carried off at any moment in one of those attacks. He told me to get her to the country, her native air, if that could be managed, immediately. That might prolong her life a little. It was only a chance, and at best a reprieve. But without it he could not answer for a week. He told me that I must be careful not to let mamma know that he thought her in danger. She was in a critical state, and any agitation might be fatal. He took his leave, and I was alone with his dreadful words in my ears. Now, how was I to carry out his directions? The journey to Golden Friars, as he planned it, would cost us at least twenty pounds, and he ordered claret, then a very expensive wine, for mamma. He did not know that he was carrying away our last guinea in his pocket. I had but half a sovereign and a few shillings in my purse. Mr. Forrester was out of town; and even if he were within reach, it was scarcely likely that he would lend or bestow anything like the sum required. The work was not sufficiently advanced to justify a hope that he would give me, a stranger, a sum of money on account of a task which I might never complete. Poverty had come in its direst shape. In the distraction of that dreadful helplessness my pride broke down. This was the reason of my wild excursion. As I now walked at a more moderate pace, I felt the effect of my unnatural exertion more painfully--every pulse was a throb of torture. It was an effort to keep my mind clear, and to banish perpetually rising confusions, the incipient exhalations of fever. What drowsiness is to the system in health, this tendency to drop into delirium is to the sick.
