Several years since I collected from the Journals to which I had originally sent them my papers on Fever. I now publish together all the papers I have written on Fever, because many of my medical friends have from time to time urged me to do it, and also because all the facts detailed and analysed were observed and recorded at the bedside and in the dead-house by myself. While collecting some of these facts in 1847 I caught typhus fever, and three or four years later typhoid fever. I mention this because it was said at the time, 'Before typhus and typhoid fevers can be said to be absolutely different diseases some one must be found who has suffered from both,' and I was the first, so far as I know, who at that time could be proved to have suffered from both. Dr. E. A. Parkes attended me in both illnesses, and had no doubt about the diagnosis in each case.
