    the names of aphthaphyte and cryptogames du 7nuguet. It is placed under the genus Oidium, and termed Oidium albicans by Robin.* The appearance of this fungus is shown in figs. 413, 422, pis. LIV and LVI. It is also found in vomited matters. 294. Diptheria has been considered by some observers to be intimately connected with the development of a vegetable growth, and thus its contagious character has been accounted for. Where, however, the fungus is found, its presence is probably explained by the view that the false membrane is a nidus very favourable to its development. At any rate it is quite certain that in many cases of diptheria, among which may be reckoned those which came under my own notice, there is no vegetable growth to be detected in the false membrane removed from the fauces.f The microscopical characters of the false membrane are described in page 187. 295. Fungus found in the External Meatus of the Ear. Asper- giUus?—The vegetable growth represented in pi. LVI, fig. 420, was removed by Dr. Grove from the external meatus of a gentleman in good health, who has been suffering from inflammation of the canal. The specimen was given by Mr. Deane to Dr. Sturt', who kindly allowed me to have the accompanying drawing of it made. J A case in which a fungus, of the same kind in all probability, was found in the external meatus of a girl, aged eight, is given by Mayer. She was a scrofulous child, suffering from discharge from the ear. Many filaments contained a receptacle filled with spores.§ Link considers this fungus to be a species of Aspergillus, and Robin places it in the same genus. || A species of Aspergillus has been detected in the human lung by Prof Dr. Carlos May Figueira, of the Medical School of Lisbon, ( Jornal da Sociedade das Sciencias Medicas de Lisboa, No. 10, Outubro de 1862). 296. other Forms of Fungi.—Low forms of cryptogamia have also been found in the lung by Professor Bennett, and have been noticed in the stools by him and other observers.

X The case, accompanied with a drawing, is given in the Transactions of the Microscopical Society, new series, vol. v, page 161. § Miiller's ** Archiv, 1844, page 404. ]1 Ilistoire Naturelle des Vegetaux Parasites, par Ch.
