In Eulenberg's _Real-Encyclopædie der gesammten Heilkunde_, 1887, page 509, article Hay Fever, we read: "Of general diseases, malaria and gout have been advanced as the basis of hay fever, but without convincing proof." We may conclude, then, that while British and American physicians know nothing about the gout theory, German physicians know about it but do not believe it. Finally, in my wanderings through German encyclopædias, I came to the many-volumed Nothnagel and here, at last, found a modern writer who knew de Mussy and recognized the importance of his observations. At the end of Volume 4 there is a monograph on Hay Fever by Dr. George Sticker, of the University of Giessen, the most thorough and satisfactory book on the subject that I have found. It may be read in English in the American edition of Nothnagel, Philadelphia, 1902. Sticker resists the impulse to begin with Galen, though he notes rather wistfully that John Mackenzie of Baltimore succumbs to it. He gives the most complete statement in any modern book of the gout theory of hay fever, but, alas, Sticker misses the pearl in the oyster. He says nothing of de Mussy's recognition of the urticarial nature of the lesion in hay fever. As this volume of Nothnagel may not be easily available to the gentle reader, I copy a paragraph from Sticker for his or her benefit. Nothnagel's _Specielle Pathologie und Therapie_, Band 4, 1896. Article _Bostock's Catarrh_, by Dr. George Sticker, page 118. "In the last few years convincing proofs are accumulating that there is a certain constitutional disorder on which the individual tendency to hay fever depends. Though further careful proof is desirable, it can scarcely be doubted that the pathogenesis of hay fever is based on that constitution that the English and French describe as arthritic, which expresses itself in a hereditary or family tendency to rheumatism, gout, diabetes, obesity, migraine, furunculosis, bronchitis, asthma, etc. Bostock himself mentioned his gouty tendency. Phoebus found it in many patients. But it was Gueneau de Mussy who first recognized the prevalence and necessary basis of the disease in the arthritism of the hay fever patient; and his teaching has been accepted and enriched with new material by Herbert, Leflaive, Lermoyez, Ruault, de Dreyfus-Brissac, Rendu, Molinie.... And so it is probably no coincidence that, like gout, the _morbus principum_ of Sydenham, so also the aristocratic hay fever is a prerogative of the Anglo-Saxon race." Reading this praise of Englishmen and Frenchmen by a German makes one sad to-day. Hasten the day when the old hearty comradeship in science will return, the day when German and Frenchman and Englishman will again praise one another's achievements ungrudgingly and each learn eagerly as of old what the other had to teach.
