I was by this time suffering the most dreadful agony, my hand and arm were so terribly swollen that they had almost lost all semblance to any portion of the human anatomy, while the two punctures made by the poison fangs were puffed up, almost to bursting, and encircled by two rings of livid grey colour.  The throbbing of the limb, as the blood forced itself through the congested passages, can only be compared to the pulsing of a stream of fire, and I am certain that, had I been within reach of qualified surgical assistance at the moment, I should have insisted upon having the limb removed, as I was convinced that the pain of amputation would have been less acute than that from which I was suffering.  Needless to say, I had no appetite for food when it was offered me a little while afterward; but I felt thirsty enough to drink the river dry, and quaffed several cocoa-nuts with an ecstasy of delight that almost caused me to forget my pain--for the moment.
