    origin. Hence, I expressed in that reply the belief, that the disease in question was not peculiar to the Continents of Europe and America, and that if diligently sought for at home the fungus would be found. Determined no longer to lie under the bondage' of opinion in such an important matter, a bondage which, till now, had prevented independent investiga¬ tion, I resolved to examine carefully every case, the symptoms of which gave reasonable grounds for suspecting the presence of an aural fungus, this was the result of my determination in one week thereafter, viz., in May, 1874, I found asper- gillus flavus in three cases; and in June, aspergill us nigricans in both ears in one case, and since then, several cases of the former variety of fungus have been seen by me in my private practice. Ho English observer had hitherto recorded such a case, and, therefore, the discovery was considered sufficiently important to merit publication. This I had the honour of doing in the lii itish Medical Journal in May last. (See ^ Mote on Fungus meatus auditorii externi.”)* Till now, my case of aspergillus nigricans (here for the first time fully reported) remains unique; but I do not hesitate to affirm that further and widespread investigation will show it to be far from rare. The varieties of vegetable fungi, which hitherto have been found in the external auditory meatus, are the follow- ing : Aspergillus flavus, glaucus, and nigricans, and the Otomyces purpurea. This latter seems, from the statement of M reden, its discoverer (see “Arch, fur Ohren und Augen heilkunde ) to be the ascomycete or utricular form of the Aspergillus nigricans. The Penieillium glaucum, Graphium penieilloides, and the Trichothecium roseum have been also found by Steudner and others. Inasmuch as the three first-named fungi are those more commonly met with, and because, as yet, I have only seen the glaucus and nigricans varieties, I limit my remarks to them. Indeed, seeing that the others were developed on slices of town? in ’ a gentleman in one of the lar/m e^e of ear cWe £ the same ™-ty of fungus iffia report of my discoveiy attentl011 havinS been cabed to the subject by the
