A text-book on diseases of the ear, nose and throat . ike the tendrils of a running vine. If a bit of deposit be torn ofi, teased in glycerin, and examined witha low power of the microscope, there will be found a mass of epithelia(an accidental circumstance) sur-rounded by irregular granules in Fig. are embedded the sporesof the various species of the lep-tothrix fungus. The general ap-pearance of the microscopic fieldis well illustrated by Fig. spores are arranged inlink-like processes, their endsbeing rounded or latter vary in length, andsometimes curl up at the endinto hair-like filaments. Othersare like colorless rods, but withsharj) dark borders, the centres seeming to be full of dark granular matter. Besides these spores thereare round or oval, highly refractive bodies with dark borders, arrangedin colonies or placed sei3arately between the branching spores. Thewhole forms a net-work composed of spores and refractive granules. Xo one has thus far succeeded in cultivating the fungus outside of the. Buccal secretion.

As lias been intimated, various species of leptotlirixthreads are constantly present in the healthy human mouth ; altered reac-tion of the buccal secretions, gastric disorders, and deposits of tartar onthe teeth all seem to favor their development. Leyden and Jaffe ^ foundthem in fetid bronchitis, tracheal ozaena, pulmonary grangrene, rhino-liths, tonsillar concretions, and vesical calculi; also in the tongue-coatingof low febrile states, in the lachrymal duct, vagina, intestines, and majority of the pharyngeal cases reported have been in youngwomen. In an analysis of a series of cases Semon ^ found age limits oftwelve and sixty two, the majority
