A female patient, M. W—, in this asylum, suffering from dementia, and who had previously been cleanly in her habits, was noticed by the nurse to soil her clothes daily, and that, although this occurred, she never had a proper movement of the bowels. She was sleepless and restless at night, but complained of no pain, and took her food in a satisfactory manner. This state of affairs had been progressing for about ten days, when it was brought under the notice of her medical attendant. Various purgatives were administered by the mouth, and these proving ineffectual, and on purgative enemata being tried and also proving abortive, a rectal examination was made, when it was discovered that the lower bowel was filled with plum-stones, which were caked with the faeces into a hard mass. These were digitally removed, and numbered about fifty. After this treatment the patient's bowels acted normally. The special feature of this case seems to be the facility with which these stones, considering their size and sharp edges, passed through the whole length of the intestine, without giving rise to any serious symptoms.
