Identify the tone in the following passage:
“It was A LOW, DULL, QUICK SOUND. I gasped for breath, and yet the officers heard it not. I talked more quickly, more vehemently but the noise steadily increased. I arose and argued about trifles, in a high key and with violent gesticulations; but the noise steadily increased. Why WOULD they not be gone? I paced the floor to and fro with heavy strides, as if excited to fury by the observations of the men, but the noise steadily increased. O God! What COULD I do? I foamed -- I raved -- I swore! I swung the chair upon which I had been sitting, and grated it upon the boards, but the noise arose over all and continually increased. It grew louder -- louder -- louder!”
