SIR,

Hackney, at page 215 of your present volume. After trying various means to remove this complaint, and even subjecting the part to the scarifying processes of the Whitworth surgeons, without any good effect, she applied to the late eminent Mr. White, of Manchester, who prescribed a remedy, which proved effectual; it was sea-bathing, long persevered in. To reside at a bathing place was impracticable. "It is not necessary," (said Mr. White) "to go to the sea, because we can produce sea-water at home. Take one pound weight of bay salt, and put it into half a hogshead of common water. In this bathe three times a week, till the obstruction be removed, changing the water when it begins to be putrid." The cure was completed in one year and a half.. Twenty years have passed since that event, and the complaint has not returned. The bathing was commenced in the depth of winter, at first by tepid water, which in a few times was reduced to its natural coldness. G. N. S.
