BRISTOL Water. Of the four principal warm waters naturally produced in England, this is the least so. As the Bath waters are proper where the secretions are defective, so the Bristol water is of service where they exceed the requirements of health. The Bath water warms; the Bristol cools. Bath water helps the stomach, intestines, and nerves; the Bristol favours the lungs, kidneys, and bladder. Except a jaundice attend, the Bristol water may be of use in dropsies by its drying and diuretic qualities. Dr Winter asserts, that there is no iron in Bristol water: and that its mineral contents are chalk, lapis calcareus and calaminaris. Five gallons of this water, after evaporation, afforded only 3 iiii. and gr. 2. of mineral substances. The diseases in which this water is useful are internal haemorrhages, immoderate menses, internal inflammations, spitting blood, dysentery, purulent ulcers of the viscera, consumption, dropsy, scurvy with heat, stone, gravel, strangury, habitual gout, atrophy, slow fever, scrophula, gleets, and diabetes, in which last it is a specific, and may be drunk as freely as the thirst requires it. The hotter months are the best for using it. The Bristol and Matlock waters are of exactly the same qualities. D. Clors Mead and Lane first established the reputation of Bristol waters in diseases of the kidneys and bladder.
