Injections containing carbonate of soda (1 to 2 dr. in the pint) form a simple and often efficacious remedy in cases of vaginal leucorrhoea with white, alkaline discharge, and in chronic cystitis an injection of borax, glycerin, and warm water is very soothing. The silicate of soda has been lately recommended for the same purpose; it coagulates albuminous material, and is antiseptic (Ranking, i., 1873).
