The upperlobe contains large patches of caseouspneumonia, some of which have soft-ened, resulting in the formation of cavi-ties. In the lower lobe smaller areas ofcaseation are found, generally with an occluded bronchus in the middle, andaround these miliary tubercles. The in-fection of the lower lobe is secondary tothat of the upper. (X natural size.) filtration as descriptiveof the stage precedingthe caseation. It wasfound by experimentthat this caseous material, when used for the inoculationof guinea-pigs and rabbits, just as surely produced tuber-culosis as when miliary tubercles were used. Moreover,on inoculation with any sort of tuberculous material acaseous pneumonia often appeared along with miliarytubercles. Weigert called attention to another way inwhich the identity of caseous pneumonia with tuberculo-sis could be established,
