Medico-Psychological Association of Great Britain and Ireland, Northern and Midland Division.—The spring meeting of this society was held on April 7th, at Scalebor Park, Burley-in Wharfedale, the new asylum erected by the West Riding County Council exclusively for the reception of private patients.—Dr. J. R. Gilmour, the medical superintendent, who was in the chair, read a paper on the Value of Saline Injections in Certain Acute Cases of Mental Disease. His method was first to empty the rectum by an ordinary enema and then to inject 15 ounces of a 0.75 per cent. solution of common salt three or four times daily. Improvement in many cases followed, the mental symptoms quietening and the pulse-rate falling. The injection was rarely returned and no bad effects had been observed. The bladder had to be watched. The treatment was most useful in severe delirious cases where the strength was much reduced.—Dr. Eddison expressed the opinion that the improvement was similar to that occurring in the febrile cases in which restlessness and excitement abated when plenty of fluid was given. In such cases the nervous system shared largely in the benefit produced by the much needed water.
