Mr. Samuel Welsh says: "I remember one evening I was in the hospital when a poor man who had been dreadfully crushed in a pit was brought in. One of his legs was so fearfully injured that it was thought it would be necessary to amputate it. After examining the patient, the doctor came to me in the committee-room--one door of which opened into the passage leading to the wards and another into the hall in the domestic portion of the building. After telling me about the patient who had just been brought in, he said, 'Do you know Sister Dora is very ill? So ill,' he continued, 'that I question if she will pull through this time.' I naturally inquired what she was suffering from, and in reply the doctor said, 'She will not take care of herself, and is suffering from blood-poison.' He left me, and I was just trying to solve the problem--'What shall be done? or how shall her place be supplied if she be taken from us by death?' when I saw a spectral-like figure gliding gently and almost noiselessly through the room from the domestic entrance to the door leading to the wards. The figure was rather indistinct, for it was nearly dark; and as I gazed at the receding form, I said, 'Sister, is it you?' 'Whist!' she said, and glided through the doorway into the wards. In a short time she returned, and I said to her, 'Sister, the doctor has just been telling me how ill you are--how is it you are here?' 'Ah!' replied, she 'it is true I am very ill; but I heard the surgeons talking about amputating that poor fellow's limb, and I wanted to see whether or not there was a possibility of saving it, and I believe there is; and, knowing that, I shall rest better.' So saying, she glided as noiselessly out of the room as when she entered. "On her recovery--which was retarded by her neglecting herself to attend to others--she called me one day to the hall-door of the hospital, and asked me if I thought it was going to rain. I told her I did not think it would rain for some hours. She then told me to go and order a cab to be ready at the hospital in half an hour. I tried to persuade her not to venture out so soon; but it was no use--she went; and many a time I wondered where she went to.
