But they did submit, and why not? Enthusiasm for Vaccination had passed away. It had been found out; it was everywhere distrusted; and those who held by it had to see it pushed on the same terms as any other quack prescription. What then was there to object to in Walker s procedure? The reason for Ring’s libels lay in Jenner’s jealousy. Walker was Jenner’s abhorrence. He had joined in the conspiracy to oust Walker from the Jennerian Society in 1806, but the operation proved fatal to the Society, whilst Walker conveyed the confidence and subscriptions of the faithful to his new Institution. What wonder, then, that Jenner disliked the eccentric Quaker! Even worse; Walker accurately appraised Jenner’s share in “the vaccine discovery,” which came, he said, from Jenner as a hint, and was developed by Pearson and Woodville in practice--a fact that was as gall and wormwood to Jenner. Moreover, Walker had written a Jenneric Opera in which Jenner was represented as a country apothecary riding up to London on a cow, and going round a-begging among the nobility and gentry. Wherefore says Ring-- As to the calumny and detraction which Dr. Jenner and his friends have received at the hands of that desperate adventurer in his Jenneric Opera and elsewhere, they are content to bear it, provided he will not again use the language of flattery toward them; nor lavish his encomiums on them in that polluted channel, the Medical Journal. His resentment can do very little harm, which is more than can be said of his adulation. “It is the slaver kills, and not the bite!” Ring was an awkward champion. He sneered at Walker’s diplomas certifying fitness to act as vaccinator-- They will have the same authority [he said] and the same virtue as a diploma from the University of St. Andrews; and in all probability will in a short time be sold at the same price-- Forgetful that it was from St. Andrews that Jenner purchased his M.D.! With equal recklessness, he denounced Walker as a vaccinator, saying-- He tells the public in his Address that “Vaccination will shed consolation into the bosom of every family;” but alas! I have known many a family that has had reason to rue the day in which they believed him, when he told them this flattering tale.... It is very necessary that his followers pray that the Lord have mercy on them, if they have no other director than Dr. Walker. Concerning the consequences of Walker’s operations, Ring, no doubt, testified truly. Many continue to rue the day when they listen to the flattering tale of the vaccinator. But the testimony came strangely from a Jennerite, who was ready to swear that any abatement of smallpox in London was due to the vaccinations effected in great part by “that desperate adventurer,” Walker!
