Dr. Young, the author of “Night Thoughts,” wrote: “They who have experienced the wonderful effects of tar water reveal its excellences to others. I say reveal, because they are beyond what any can conceive by reason or natural light. But others disbelieve them though the revelation is attested past all scruple, because to them such excellences are incomprehensible. Now give me leave to say that this infidelity may possibly be as fatal to morbid bodies as other infidelity is to morbid souls. I say this in honest zeal for your welfare. I am confident if you persist you’ll be greatly benefited by it. In old obstinate, chronical complaints, it probably will not show its virtue under three months; though secretly it is doing good all the time.” KINGS BUY SECRET REMEDIES. In past times it was not unusual for monarchs to purchase from the inventors of panaceas the secrets of their composition for publication for the benefit of their subjects. Several instances are mentioned in other chapters of this book. Among these may be noted Goddard’s Drops, bought by Charles II., Glauber’s Kermes Mineral or Poudre des Chartres, Talbor’s Tincture of Bark, and Helvetius’s Ipecacuanha, the secrets of which were obtained by Louis XIV for fancy prices. In Louis XIV’s reign the French Government purchased from the Prieur de Cabrier an arcanum to cure rupture without bandages or operations. The recipe, which was made public, was that a few drops of spirit of salt were to be taken in red wine frequently during the day. Mr. Stephens’s Cure for the Stone was transferred to the public by a payment authorised by Act of Parliament. The Emperor Joseph II of Austria paid 1,500 florins somewhere about the year 1785 for the formula for a secret febrifuge which was at that time enjoying extreme popularity. It proved to be simply an alcoholic tincture of box bark (_Buxus sempervirens_). The remedy lost its prestige as soon as the secret was gone. _Nouffer’s Tapeworm Cure._ Louis XVI gave 18,000 livres (about £700) to a Madame Nouffer or Nuffer for a noted cure for tapeworm, which she had inherited from her deceased husband. As the result of the king’s purchase, a little book was published in 1775 explaining fully the treatment.
