"One bottle I found in the medicine chest was a great prize to me. It contained iodine and, with a weak solution of this, I was able to maintain my colour. I did not care so much for my face and hands, for I was so darkened by the sun that my complexion was little fairer than that of many of the Arabs. But I feared that an accidental display, of a portion of my body usually covered by my garments, would at once prove that I was a white man. I had used up the stuff that I had brought with me, when I escaped from the square; and having no means of procuring fresh stain, was getting uneasy; but this discovery of the iodine put it within my power to renew my colouring, whenever it was necessary.

"About a month later. I have been living here quietly, since I last wrote in this journal. The day after I had done so, the Emir sent for me, and said he had heard that I had taken bullets out of wounds, and had shown the two doctors of the town how to do so, by means of instruments found in a chest that was among the loot brought in from the battlefield. I repeated my story to him, as to how I had acquired the knowledge from being in the service of a white hakim, from Cairo, who was travelling in the desert; and that I had no other medical knowledge, except that I had seen, in the chest, a bottle which contained stuff like that the white doctors used in order to put a patient to sleep, so that they could take off a limb without his feeling pain.

"'I have heard of such things being done by the Turkish hakims at Khartoum, but I did not believe them. It is against all reason.'

"'I have seen it done, my lord,' I said. 'I do not say that I could take off a limb, as they did, but I am sure that the stuff would put anyone to sleep.'

"'I wish you to put it to the trial,' the Emir said. 'One of my sons came back, from the battle, with a bullet hole through his hand. The hakim said that two of the bones were broken. He put bandages round, and my son said no more about it. He is a man who does not complain of slight troubles, but yesterday evening the pain became so great that he was forced to mention it; and when I examined his arm, I found that it was greatly swelled. Slaves have been bathing it with cold water, ever since, but the pain has increased rather than diminished.'

"'I will look at it, my lord, but I greatly fear that it is beyond my poor skill to deal with it.'

"The young man was brought in and, on removing the bandage, I saw that the wound was in a terrible state, and the arm greatly inflamed, some distance up the wrist. It was a bad case, and it seemed to me that, unless something was done, mortification would speedily set in.

"'The two doctors saw it an hour ago,' the Emir went on, 'and they greatly fear for his life. They told me that they could do nothing, but that, as you had seen the white hakim do wonderful things, you might be able to do something.'

"'My lord,' I said, 'it is one thing to watch an operation, but quite another to perform it yourself. I think, as the doctors have told you, your son's life is in great danger; and I do believe that, if there were white doctors here to take off his arm, he might be saved. But I could not undertake it. The skill to do so is only acquired by long years of study. How can I, a poor man, know how to do such things? Were I to attempt and fail, what would you say?--that I had killed your son; and that, but for me, he might have recovered.'

"'He will not recover,' the Emir said, moodily.
