There is no record of any objection to the title. In 1778 Bergmann published a treatise on artificial mineral waters, giving analyses of the most popular, and recommending the use of the factitious waters as preferable to the natural ones. About the same time a French pharmacien, named Vanel, introduced a powder with which to make the favourite Eau de Seltz, or Selters water. Apparently the salts for making mineral waters acquired a certain degree of popularity, and it is likely that Seidlitz salt was among them. Nothing would make this palatable, and Mr. Savory’s idea of substituting a pleasant draught for a nauseous one was at least a commercial success. TURNER’S CERATE. Daniel Turner, M.D., the inventor of Turner’s Cerate, which appeared in several Pharmacopœias as Ceratum Calaminæ, was at first a surgeon in London, but was admitted a Licentiate of the College of Physicians in 1711, and practised in Devonshire Square, Bishopsgate. In William Munk’s Roll of the Royal College of Physicians an opinion of him is quoted that he was too fond of displaying his talents upon paper; the result being that he published many volumes which are now forgotten. (A commentary which might be made on most other authors.) It is also said of him that his cases were not stated in the most delicate terms, nor was politeness among his excellences. As several of his works were about syphilis it may be that his style was merely perspicuous. He wrote comments on Dover’s “Ancient Physician” and on Mr. Ward’s Pill and Drop. His biographer, however, quotes from him with approval a pious exhortation to physicians not to be ashamed to avow their religious principles even if they kept their politics to themselves. “It can be no disgrace,” he wrote, “for a physician who owns himself to be no more than Nature’s minister to acknowledge himself also the servant of Nature’s Master.” Turner’s original formula for his Ceratum de Lapide Calaminari was to melt together 3½ lb. of freshly made unsalted butter, 3½ lb. of the best yellow wax, and 4 lb. of pure and newly-prepared olive oil. These when melted to be strained through a linen cloth, and while cooling, 3 lb. 10 oz. of the best calamine stone, “sufficiently triturated and passed through a Sierce,” to be sprinkled into the mixture with constant stirring till it sets. Turner’s comments on this cerate are worth quoting, because they incidentally illustrate the pharmacy of the period. He says:--
