HISTORY OF THEUSH. 215 



article " Muguet"), the name muguet is derived from the resem- 

 blance in colour and form to the flowers of " Convallaria maialis ;" 

 Heyfelder (1828) ; Guersant and Blache (ibidem, 2d edition, 

 carrying out further Wedekind's views) ; Lelut (1827) ; Billard 

 (1827), " Stomatitis follicularis " = aphthae and stomatite avec 

 alteration de secretion = muguet; Duges (1829) only increases 

 the confusion; Pieper (1831) like Billard, he does not, however, 

 perceive the resemblance to mould, and describes the Stomatitis 

 follicularis, the latter being entirely confounded with thrush by 

 Rau (1831) ; Eisenmann (Stomatopyra Soor and Stomatopyra 

 aphthae, which are exanthems) ; Gordinet (aphthae, a disorder of 

 the mucous glands ; muguet, an exudation) ; Naumann (aphthae = 

 a formation of phlyctenae ; soor = Stomatitis exsudativa, or in the 

 2d edition, Angina aphthosa) ; Bouillaud, de la Berge, and 

 Monneret, who caused great confusion; Schnitzer and Wolff; 

 Bouchut calls aphthae what is, in fact, Stomatitis follicularis, and 

 applies muguet to the real fungus. All the renowned medical 

 authorities of France and Germany, down to Cannstatt, when he 

 wrote his first edition, share the faults spoken off, and it appears 

 to me superfluous to enumerate them all. The exceptions will 

 be mentioned in the last period. 



6th period. Period of the proof that aphtha and muguet are 

 identical. Double (1803), it is no inflammation, but a disease 

 which occurs on red spots, forming white pustules ; O. L. Bang ; 

 Heyfelder thinks that aphthae and muguet are synonymous he 

 confounds, however, aphthae and Stomatitis follicularis. Bark- 

 hausen thinks that Peyer's and Brunner's glands were often mis- 

 taken for aphthae. Frankel (1838), muguet, a variety of aphthae. 



Period of the knowledge of the true fungous nature of aphtha. 



Jahn first observed, in Hufeland's ' Journal/ 1826, that the 

 people had rightly conceived a similarity to exist between this 

 disease and mould, and compared the physical development of 

 both. But as he did not believe the lowest moulds to consist of 

 really organized plants, he also viewed these fungi merely as 

 physico-chemical products. He is of opinion that a peculiar 

 fungous mass exists, and that the fungi are sometimes produced 

 by other species of mould, as, for instance, Merulius destruens.
