I dreamed that I was taking a cold bath, and that while thus engaged a Turk, armed with a pair of long pincers, came into the room and began to pull the hair out of my head. I remonstrated, but was unable to offer any material resistance, for the reason that the water in which I was lying suddenly froze, leaving me imbedded in a solid cake of ice. In order to facilitate his operations, the Turk sponged my head with boiling water, and then, finding the use of the pincers rather slow work, shaved the hair off with a red-hot razor. He then rubbed an ointment on the naked scalp, composed of sulphur, phosphorus, and turpentine, to which he immediately applied fire. Taking me in his arms he rushed down stairs into the street, lighting his way with the flame from my burning head. He had not gone far before he fell down in a fit, and in his struggles gave me a severe blow between the eyes which instantly deprived me of sight. When I awoke in the morning I had a very distinct recollection of this dream. The incidents were in part due to the fact that I had, two or three days previously, been reading an account of the insanity of Mohammed, and of his being subject to attacks of epilepsy. The sense of taste is not, for obvious reasons, so productive of dreams as the other senses, but the experiments of M. Maury and myself, to which fuller reference will presently be made, show that strong excitations made upon it are transmitted to the brain; and the following instance, which has recently come under my immediate observation, is an interesting case in point.
