ACCIDENTAL ADMIXTURES OF EXPECTOEATIOK Before discnssing specially tlie sputum, we will mention acci-dental admixtures. They are principally remains of food, wMclimay even cause diagnostic errors, when, for want of practical ex-perience, muscle-fibers may, e. g., be taken for parts of the lung;small bread-crumbs are frequently found in muco-purulent spu-tum; the amylum grains are then swelled and present a prettyaspect. Generally, however, these admixtures are so characteristicthat they may only confuse an inexperienced examiner. PLATE. Accidental constituents of expectoration. ( Muscular fibres and amylum grams /.

Occasionally we find the follicles of tlie tonsils after acute in-flammation closed by white plugs; or this plugging appears as anindependent chronic disease, which, by a constant irritation, causesa continual desire to cough and hawk. Microscopically, these plugs consist of a granular mass of de-tritus in which are imbedded: Large numbers of different-sized needles of mar gar Ic aoid , Fat-globules from the smallest to the largest size; Pus-corjpuscles in a state of dissolution; Threads of l&ptothrix, partly without any regular arrangement,conglomerated with the detritus, or else in the form of beautifullarge sprays; finally, A colony of micrococci in half-moon shape. These same plugs, only much larger, are found in the sputumof putrid bronchitis and pulmo
