After reading de Mussy's argument for the dependence of hay fever on a gouty diathesis, I turned first to the English books. For centuries, England has been famous as the home of gout and, since the Englishman, Bostock's, account of his own case, hay fever, too, like parliamentary government and gout, has been recognized as an inheritance of the Anglo-Saxon race. As British physicians see more gout than any other physicians in the world and as, for many years, they have had the best opportunities for the study of hay fever, I turned first to the English books, thinking that if there was any truth in the gouty theory, the British physicians would have found it out long ago. To my surprise I searched book after book by both British and American authors, but in not one instance did I find hay fever associated with gout. These books included Allbutt's _System of Medicine_, F. T. Robert's _Practice_, Lennox Browne, Morell Mackenzie in England and, in this country, Ballenger, Bosworth, Coakley, Kyle, Solis-Cohen, Ivins and Vehslage and Hallett. No one is more saturated with the traditions of British medicine than Sir William Osler, but, in his _Practice of Medicine_, in discussing the constitutional causes of hay fever, he seems to know nothing of the gouty theory. Besides the article on hay fever in his _Diseases of the Nose and Throat_, Sir Morell Mackenzie wrote a comprehensive work on _Hay Fever and Paroxysmal Sneezing_ that ran through five editions and bears on the flyleaf the admiring comment of the _London Lancet_ that it "must be regarded as one of the most complete expositions of our knowledge of this curious complaint in our language." It is a wicked joy to catch such a scholarly writer as Mackenzie napping. In a footnote he even refers to the de Mussy lecture in the _Gazette hebdomadaire_, Jan. 5, 1872, as calling the disease spasmodic rhinobronchitis, with which name the disease is still known in France. One suspects that the learned Doctor was very busy that day and that the footnotes were looked up by somebody else; for, though he gives "the most complete exposition in our language," as the _Lancet_ puts it, of the constitutional causes underlying hay fever, there is never a word of de Mussy's theory of gout. In Osler and McCrae's _Modern Medicine_ the article on Hay Fever is written by Professor Dunbar, of Hamburg, deviser of pollantin. Here at last we get away from British insularity, for, in spite of his Scotch name, Dunbar is a German. On page 863 he writes: "For a long time it has been believed that the predisposition to hay fever rests on a gouty diathesis. This view is not on the face of it inconsistent with the pollen theory. Inquiries, however, have shown that gouty persons form only a small portion of hay fever patients."
