The Dog and Duck was in existence as a small inn as early as 1642.[302] In its vicinity were three or four ponds in which, no doubt, the brutal sport of hunting ducks with spaniels was at one time practised,[303] and near the place were mineral springs whose properties were known as early as 1695, though the water does not appear to have been advertised for sale till about 1731,[304] when the Dog and Duck had taken to itself the imposing sub-title of St. George’s Spaw. At this time the water was sold at the pump for fourpence a gallon, and was stated to be recommended by eminent physicians for gout, stone, king’s evil, sore eyes, and inveterate cancers. A dozen bottles could be had at the Spa (_circ._ 1733–1736) for a shilling. From about 1754 till 1770 the water was in considerable repute, and new buildings appear to have been erected for the accommodation of visitors. There was a long room for breakfasting (1754), a bowling-green, and a swimming-bath (1769) two hundred feet long and nearly one hundred feet broad. Tea and coffee were to be had in the afternoon. At this period people of good position seem to have frequented the Spa or to have sent for the water. We find Miss Talbot writing about the place to Mrs. Carter, and Dr. Johnson suggested the use of the water to Mrs. Thrale.[305] The proprietors issued (1760) to subscribers an admission ticket handsomely struck in silver with a portrait of Lazare Rivière, the famous Professor of Medicine, on its obverse.[306] The _St. James’s Chronicle_ ranked the water with that of Tunbridge, Cheltenham, and Buxton. Physicians of repute described its curative properties, and affirmed it to be excellent for cutaneous afflictions and for cancer which it would certainly arrest, even if it did not cure. This water, which was advertised as an aperient (Epsom Salts being also kept on the premises), came at a much later date--1856--under the observation of Dr. Rendle, the historian, and, as it happened, the Officer of Health in that year for the Parish of St. George’s, Southwark. Rendle procured an analysis of water from the superficial well, formerly the spring, on the site of the old Dog and Duck and was forced to describe it as “a decidedly unsafe water” containing impurities, eighty grains per gallon, chiefly alkaline chlorides, sulphates and nitrates, gypsum and carbonate of lime, with a little phosphoric acid.
